Handy Tips & Tricks to help you set up your system

Getting a soundbar for your TV can take the entertainment experience in your home to a whole new level. It is a legitimate way of enjoying your music or watching the latest blockbuster movies with a true surround sound.

Now, if you’ve just bought a soundbar, you might be wondering what the best way to connect it to your TV is.

You’ll be glad to know that there several ways to go about, and depending on your TV design or personal preferences, your television will have the sound quality you desire.

In this post, we will consider some of the options you have; particularly how to connect the soundbar with an optical cable and without one.

How to Connect Soundbar to TV using Optical Cable

Soundbar Back ports

First off, we will look at how you can improve the quality of sound on your TV set by connecting it to a soundbar. Follow the steps below:

  1. Check the optical cable to see if there are any protective plastic caps fitted at the ends; if any, remove them to ensure that the cable will plug into the various ports/

  2. Locate ports on your TV marked for Digital Audio Out. This port releases an optical signal that can be passed on to a soundbar, speakers, or any other compatible device.

  3. Plug in your optical cable into the Digital Audio

  4. Out port on your television.

  5. Plug the other end of the optical cable into the Digital Audio In port of the soundbar you want to connect. 

  6. Ensure that you are connecting from the Optical Output port on your TV to the Optical In on your soundbar so that data flows from the TV to the soundbar to produce sound. Doing the opposite won’t work!
  7. Switch on the power on both the TV and soundbar.

  8. Press the source button on the soundbar’s remote control and set it to digital IN. “D-IN” will be displayed on the front panel of the soundbar to show that it is ready to go.

There are various reasons you’d want to connect your soundbar to your TV without an optical cable. Maybe your television is just too old or perhaps you just like doing things your way. Whatever the reason, you’ll be glad to know that there are several ways to achieve this:

Connecting Wirelessly via (Bluetooth)

If you are looking to ditch all that clutter and tangle of cables in your living room, connecting with wireless technology is the best solution you have. The process is generally easy, especially if you are working with Bluetooth soundbars under $200.

  1. Firstly, you’ll need to enable the Bluetooth on your soundbar so that the device is discoverable. This will allow you to establish the connections; soundbar and the TV.

  2. Enabling Bluetooth is fairly intuitive, but will vary from one device to another, depending on the soundbar model you are using. In most cases, you will find a dedicated Bluetooth button, either on the soundbar or remote control, that you’ll need to press and hold until the LED indicator lights up.

  3. Once your soundbar is in discoverable mode, you can now move to your TV. Usually, this will require navigating through the settings with your remote control. For some Tv models, simply press the home button and scroll your way to the Add Accessory menu; here the TV will automatically start to search for Bluetooth devices.

  4. If your TV is not Bluetooth enabled, there are several adaptors you can use to connect a sound signal source to a Bluetooth signal. This should enable you to establish a Bluetooth connection.

Once you have connected the two devices, you can press play to start enjoying your music or movie.

How to Connect with Aux Cables

In case your TV doesn’t come with wireless capabilities, you can opt for aux cables to connect your soundbar. Some TV models have a 3.5mm output jack that you can use for this.

The connections involved are quite straightforward; the same kind that is used in headphones. Just plug one end of the cable into the TV and the opposite end into the soundbar.

If your soundbar lacks a 3.5mm input, you can buy an AUX to RCA cable on Amazon. The cables are relatively cheap and serve to divide the stereo signal between two RCA cables.

The problem with this method is that you only get right and left sound. This means if you have a 3.0 soundbar or anything higher, you might not get the best sound quality. 

How to Connect with RCA Cables​

Most TV models with wireless capabilities or a 3.5mm output also come with HDMI or optical ports. But older TVs only have RCA and coaxial inputs, and in this case, the soundbar will usually cope with a two-channel RCA configuration.

Ensure that you have RCA output ports on your TV and not input ports. If not, you might have to split the signal before it reaches the TV. You can do this by connecting the yellow video cable to the TV and the red and white radio cables to the soundbar. 

Just like with the 3.5mm cables, RCA cables mostly have left and right output. Therefore, you’ll need to improvise with the center channel of a 3.1 or 3.0 soundbar.

In some situations, there will be a 5-channel RCA output that you can hook up the right, front left, and center jacks to your soundbar. However, most soundbars with three speaker channels or more will only connect with optical and HDMI cables or wirelessly.

How to Connect with HDMI Cable

This is a fairly simple process, but before you start, ensure that your TV supports HDMI-ARC, which enables sound to travel along a cable on both sides. ARC or Audio Return Channel allows you to use HDMI as an audio input, as well as audio output.

HDMI Connector

Most HDMI ports on TVs are only input, meaning they won’t send any data from the TV. They strictly receive data. If your TV supports ARC, you can connect all your kits (like set-top box) to the soundbar and use the HDMI cable to connect your soundbar to your TV. 

Follow the steps below to connect a soundbar to your TV:

  1. Turn on both the TV and soundbar

  2. Find the HDMI OUT port on the soundbar and plug in the HDMI cable.

  3. Locate the HDMI ARC port on the TV and plug in the free end of the HDMI cable then you can start enjoying the surround sound.

With the latest of quality soundbars under $300, you’ll need to select the HDMI option to enable the audio output. The benefit of using HDMI cable is that you’re able to transmit huge amounts of audio data. 


The easiest way you can connect a soundbar to your TV is by using an optical cable. However, many TV models don’t come with an optical cable input, which may force you to experiment with alternative methods of getting these connections without the optical cable. 

Luckily, the other methods available to you have been discussed in the article. So, if you have a TV model that doesn't support an optical cable, you can rest assured that it won’t stop you from reveling in the quality surround sound that even a cheap soundbar can offer.


Do you need an optical cable for a soundbar?

An optical cable will help you to connect a soundbar to your TV. However, you don’t always need it to connect the two devices; there are alternative ways of doing this. For instance, you can connect them wirelessly via WiFi or Bluetooth technology if both devices are compatible or use an HDMI cable. You can as well opt for RCA or AUX cables to connect your TV with soundbar. 

Is Optical Audio as Good as HDMI?

Both optical and HDMI cables help to transmit digital audio between devices. They both deliver a better sound profile than the red and white analog cables. The main difference between them is that HDMI can transfer higher-resolution audio, such as formats found on Blu-ray- DTS HD MASTER Audio and Dolby TrueHD

What is Optical Cable for Soundbar?

An optical cable for soundbar is an optical digital-audio cable that is used to connect the soundbar to a TV to improve sound quality. It is usually included in the package when you buy a soundbar for TV and features a relatively easy installation process.

How do bluetooth speakers work: Wireless Speaker Guide

How do bluetooth speakers work: Wireless Speaker Guide

Handy Tips, Tricks & Useful information

Entertainment, in general, has come a long way ever since the introduction of Bluetooth technology. Gone are the days when speakers needed loads of wires connected from an audio system to function. 

Considering its extensive application; from car audio systems, home audio systems, and outdoor speakers to Bluetooth speakers you can use in the shower, we can conclude that Bluetooth is the new normal!

Even though the speakers have been in the market for a while now, most people still don’t understand the technology behind these relevant entertainment devices. So, just how does a Bluetooth speaker work?

What is Bluetooth?

For you to understand how wireless Bluetooth speakers work, you must start by understanding how we use a phone to talk to each other. Cell phones make use of radio waves to communicate to cell towers, which can be located as far as a couple of miles away.

Bluetooth technology, on the other hand, uses considerably weaker radio waves. This means that the range will not exceed 10 meters. As such a Bluetooth speaker should be placed a few feet from the audio streaming source for it to work.

While the most advanced devices (mostly for industrial use) will give a range of about 100 meters, you will rarely find the same range in consumer appliances.

Essentially, Bluetooth speakers are a kind of speaker that improves the convenience of listening to music or watching movies. Unlike traditional speakers, they eliminate the need to connect a cable or wires from the audio source.

This allows you to remotely use speakers on stereo systems, tablets, iPods, and even a smartphone without having to connect any wires to a specified jack port. You also get to move around with the speaker without having to carry the entertainment source.

​How Bluetooth Speakers Work

There is normally a level of confusion when it comes to Bluetooth vs WiFi speakers. The thing is both are a type of wireless speakers that don’t require wires to be connected to the sound system.

However, you need to know that the two function quite differently.

Bluetooth speakers use the same technology and protocol found in phones and car speaker systems. Sound is transmitted wirelessly from the source through airwaves to the receiver, in this case, the earpiece.

This is unlike WiFi speakers that require a bridge between the speaker and the audio source.

Synchronizing Bluetooth devices together is quite easy! The connection between them is established automatically as soon as you activate the devices when they are within range.

The communication occurs over a piconet- short-range network and can include multiple Bluetooth devices.

Once you have your Bluetooth speaker and the relevant audio source within a single piconet, the two connect automatically and are able to communicate. One will act as a control center while the other acts as a discoverable device.

This is the same way your Bluetooth keyboard automatically connects to your mouse as soon as you start your PC and you can also change the settings and properties.

We can conclude that Bluetooth is, in essence, not only a communication technology. The same way other wireless technologies work, Bluetooth also offers data transfer capabilities. This is why your portable speaker is able to play the audio from your stereo system.

What are the Benefits of Using Bluetooth Speakers?

A Bluetooth speaker offers you various benefits; one being that you don’t need any tech skills to operate or set up. You simply switch on the Bluetooth speaker and once your audio system discovers the speaker, the two devices automatically sync with each other and the music is played.

Generally, these wireless speakers are more compact compared to other types of speakers but produce a high-quality and clear sound, which makes them the perfect appliance to have at home.

Their compact design also makes them quite portable and you won't believe how handy a blackweb speaker comes in when you want to move around while listening to your favorite playlist.

Furthermore, the absence of connecting wires ensures there is minimal clutter in the home or studio.

The Bluetooth speakers are highly versatile and compatible with a range of entertainment devices, including tablets, laptops, smartwatches, smartphones, just to mention a few.

Finally, the limited range of these speakers can also be an advantage in that it prevents the transmission of large amounts of data over large distances and areas, which may interfere with the operation of other connected devices or networks.

The Downside of Bluetooth Speakers

Bluetooth speakers are great when it comes to affordability and convenience. However, they have a security concern that you should always watch out for. Hackers can easily intercept the signal from your phone and hack into it using software. 

Connecting to an unsecured connection makes your phone vulnerable to hackers who may access photos, videos, texts, and whichever information you have on your phone and mess up the whole experience.

It is always wise to take the relevant precautions, in a world where multiple devices are continually getting wirelessly connected and hackers lurking in the background. 

Another limitation is that your speaker will only be able to function over a short distance. It needs to be a few feet away from the audio source for the two devices to sync and communicate. 

​Selecting the Right Bluetooth Speaker

The rapid growth in audio streaming technology and the explosion of online music-streaming services are making Bluetooth speakers one of the hottest properties in the Bluetooth devices market.

With this comes an increased rivalry between brands that has led to all size and manner of Bluetooth speakers.

It is easy to get overwhelmed by the immense number of options available to you. You simply need to visit your neighborhood store or go online to find the best Bluetooth speakers for less than 100 bucks.

However, these speakers are built differently and not all will offer you the sound listening pleasure you are looking for. 

If you are trying to get the best deal, you should always pay close attention to the brand reputation, product reviews, dealer experience, as well as your personal preferences.

No need to panic if you are wondering how to buy on a tight budget too, you can find the best Bluetooth speakers under $50 that will still offer you the quality you deserve.


Bluetooth devices such as car audio speakers and home speaker systems are getting more and more popular thanks to their convenience and overall benefits that they provide.


That’s why it not surprising that you’ll find at least one Bluetooth device in the average home that you visit today.

Understanding the principles behind the functioning of Bluetooth technology , knowing the overall advantages of using these speakers, and choosing the appropriate product is essential if you want to improve the experience of listening to music in your home.  

It is advisable to search for the appropriate models in the market by comparing competing brands and liaising with trustworthy dealers to have a fulfilling experience. In addition to the satisfaction, you won’t have to keep on asking questions such as “what is a Bluetooth speaker?”. 


How Can I connect to a Bluetooth speaker?

Before you can pair any audio devices to your wireless speaker, you must first ensure that the speaker is in pairing mode for it to be discovered by the phones or tablets you are using for the initial setup.

Although each speaker enters into pairing mode using a different method, these two tips should allow you to get your Bluetooth speaker to work quickly:

Hold Down Power

Most Bluetooth speakers will get into pairing mode when you turn off the speaker then power it back on while holding your finger down on the power button. The speaker will then notify you that it is in pairing mode by either producing a sound or rapidly flashing its light indicator. 

Hold Down Pairing Button

In some cases, the Bluetooth speakers have a dedicated button that will place the speaker into pairing mode. Try to locate the button on the speaker (usually with the Bluetooth icon next to it) and press on it until you hear the sound notification or see the light indicator.

With the Bluetooth speaker now discoverable, enable Bluetooth on your cellphone to pair the two devices and turn up the volume to start enjoying your favorite playlist. However, if the methods above don’t apply to the speaker you are using, check the manufacturer’s user manual for proper guidance.

Do you need an Internet connection to use Bluetooth?

No! Bluetooth does not require the internet to transmit data. The same way a Bluetooth speaker won’t need to be connected to the internet to play music coming from a paired audio source. 

This is because Bluetooth devices communicate with one another regardless of an internet connection.  

For instance, when you are using a Bluetooth keyboard, the keystrokes don't get transmitted to the internet and back to your computer.

On the contrary, the transmission goes directly from the keyboard to the tablet or computer. 

In short, your Bluetooth speaker will function perfectly without connecting to WiFi connection. In fact, Bluetooth is already a wireless transmission technology so the internet doesn’t enable or improve its functionality.

What Speakers Fit My Car?

Handy Tips & Tricks to help you make the right choice

So, your automobile’s audio system has been acting up lately and you can’t wait to upgrade it with a set of fresh and booming speakers.

One problem though, you just can’t seem to decide which type of stereo system is best suited for your vehicle.

The best speakers to fit in your car will ultimately depend on the kind of music you listen to. Normally, different types of music will require different speaker setups to deliver the needed quality of music.

And the most expensive option doesn’t always reflect the highest quality you can get!

Choose Quality When Shopping for a Car Speaker

Selecting the best auto speakers is not a routine activity that anyone can perform. However, it will go a long way to save you the cost of constantly replacing your automobile speakers.


If the pre-installed factory speakers you find in the car do not measure up to your preferred sound quality, you might want to look for a relevant upgrade.

But before you embark on a project to soup up your new ride, you want to make sure that you are getting the best fit of speakers for your car, especially if you’re thinking of replacing the factory speakers.

There is no point in spending a fortune on a new set of speakers only to come and realize later on that they are not suitable for your ride.

To save yourself all the trouble and disappointment, you will have to pay keen attention to the speaker's size and type. 

After all, one crucial feature in the most sought-after vehicles today is the existence of the best fit of speakers. And this is exactly what you’ll learn as you go deeper into this article. 

Speaker Sizes

What are the Different Categories of Car Size Speakers Available?

The first thing to consider here is the type of speaker products that will complement your vehicle’s stereo system. This will also be determined by the kind of audio system that your vehicle is compatible with. Let us look at some of the different sizes of speakers you’ll find in the market:

Woofers and Subwoofers

If you are interested in the kind of music that will boom at every inch of the car, woofers and subwoofers will be the best choice for you.

These come in different sizes, from 8-ich subwoofers to 15-inch subwoofers and deliver a high bass and range of sound as the products increase in size. These are also the biggest car speakers you can get.

6 by 9-inch Speakers

If you are looking for a decent sound-range with less bass power than what a woofer or subwoofer offers, then try a 6 by 9-inch speaker. These have a relatively more compact size, but will still require a decent amount of space to be installed.

5 by 7-inch Speakers

One thing you’ll love about the 5 by 7” speakers is the high level of sound clarity it offers alongside a wide sound-range. These come in a reasonable size, so space shouldn’t be an issue for you. A 5 by 7” can handle more power while distorting less than smaller speakers. 

Another advantage is that it can fit in a large variety of car models. The only limitation is that it can only use specific ports.


5-inch Speakers

These speakers are what you’ll find in most vehicles and offers a good range of sound. Its versatility ensures that it fits in almost any car model you can think of and they play low, as well as high-frequency music with equal efficiency. 

These speakers come with stiff yet lightweight cones to handle harder kicks and deliver a more efficient response thanks to a higher handling capacity.


This speaker type falls within the 1 by 2-inch range of car speakers. Tweeters provide amazing sound support to the existing audio systems. They help to improve the quality in your car stereo system. 

Choosing the Right Speakers for your Vehicle

When in search of the appropriate speakers for your car, be sure to follow the tips below:

Decide on the kind of speakers you want: This is the first thing you should have in mind.

Determine your price range: Choose a price range that you’ll be comfortable with when buying the products.

Check the speaker configuration: Ensure that the speaker you choose is compatible with your automobile’s audio system.

Match the speakers with the automobile’s stereo: This will require you to

  • Measure the speaker size 

  • Check the sensitivity 

  • And determine the power-handling


Important Features of a Speaker that will Determine the Right Size for your Auto Speaker

Establishing the size of a car speaker can be a tough ask, but this is a puzzle that has already been solved for you. Sometimes, it's more essential to consider the size of the speaker as a category rather than taking it as an individual size. 

In essence, being aware of the measurements determining you’re the size of your speaker may at times go beyond considering it as a mere category.

These determining parameters include speaker diameter, mounting height, and mounting depth. 

Let us take a deeper look at each parameter.

Speaker Diameter

This refers to the distance between the outside frames or the diameter of non-circular frames. In case you are considering a change to the arrangement of your mounting to create more space for an extra speaker, you will need to know the speaker's diameter. 

In such an instance, you’ll need to know the speaker's diameter to accommodate the new set up configurations. The mounting ports for speakers with a similar diameter size are usually the same and standardized. 

Some speaker ports come with adjustment devices that allow you to drill any new holes you want to when installing speakers.  This is a crucial feature worth considering and may come in handy depending on how you want your new car speakers installed. 

Another important parameter is the cut-out diameter; usually associated with the speaker's diameter. This is determined by measuring the distance from the mounting holes to the center of the cone surround. 

Mounting Depth

The mounting depth refers to the distance from the mounting plane to the back of the speaker. This parameter comes in handy when you want to replace or improve the speakers in your car.

Although most automobile speakers are usually installed on the vehicle’s doors, there are some instances when the car door clearance may not be deep enough for the new speakers to fit. 

This means you need to determine the car door clearance available by either measuring the clearance or your car speakers and use this information to ensure that the shallow mount subwoofers you are getting do not go deeper than the available door clearance. 

Mounting Height

This is the distance from the outer extension of the speaker’s front part to the mounting plane. The majority of the coaxial speakers have tweeters protruding from the front plane.

This implies you’ll need to prevent the tweeter from constantly hitting the grille with the help of a spacer.

Other Ways You Can Determine Your Automobile’s Speaker Size

There are several methods of determining your car speaker size, and this will help you choose the right fit for a new speaker system you intend to install on your car.

It is something that you should always consider if you appreciate great music listening experience whenever you are driving vehicle. As such, consider the following ways of determining car speaker sizes:

Measure the Speaker Brackets

This involves reading the marker on the speaker slots. Note that this method has a limitation in that some cars lack speaker boards and/or speaker size markers. The method may, therefore, not apply to some vehicle models.

Online Tools

You can also find online databases with good information concerning every automobile model and the sizes of speakers it can accommodate. All you have to do is input your vehicle model and the searcher will provide a list of speaker sizes that will fit the model. 

These online tools assist you to figure out the correct fit of car speakers by analyzing the features and model of the car. They will further test for clarity, balance, and other aspects associated with the car model.

A good online tool you can use is "online car stereo".

Car Manual

Another way you can determine your car speaker size is by referring to the car manual. There is information provided under the audio system action that contains accurate and absolute speaker sizes for your car.

This will be important in case you want to improve the stereo system with speakers that are the same size as the factory speakers. 

The manual will as well guide you in knowing whether your speaker system is expandable.

Trial and Error Method

This method involves randomly experimenting with different size speakers to see which one among them will fit into the mounting hole. You should be warned, however, that this method can be tedious and frustrating.

Other Considerations to Make Before Buying Car Speakers

Woofer Quality

Before you look at the speakers, be sure to check the woofer quality. A good woofer has stiff and light materials to deliver a quality bass. Manufacturers tend to pair polypropylene with other materials to give off a more accurate bass response. 


The sensitivity of a speaker is how much sound it can yield. Every speaker needs power which determines the level of sound being produced.


Normally, factory stereos feature low power of around 15W RMS per channel or less, which will ideally require a speaker with high sensitivity- over 90dB. 

On the other hand, if the car comes with a high-power stereo system, get a speaker with low sensitivity. 


This parameter is usually indicated by the RMS rating. It refers to the total amount of power that a speaker can handle continuously.

For a low-powered system, you don’t need to get a speaker with a high RMS rating while for a high-powered system, the RMS rating should be near the output of the power source. 

It is recommended that you get speakers with an RMS rating matching the power source output to get the best speaker experience. 


The next time you are wondering “what speakers fit my car?” the above post will help you find the appropriate answer.

Ultimately, the right answer will depend on the car model you’re driving and there are various ways you can figure out the speaker size as discussed above. 

We believe the information provided will help you find the best speakers to effortlessly fit in your car and greatly improve your listening experience while driving.



What are the best speakers for a car?

Depending on the car model you’re driving and the kind of music you want to play in your car, the following are some of the best car speakers you can get:


How much does it cost to get speakers installed in your car?

The cost of installing new speakers will vary depending on the type of speakers you want to be installed and the scope of work to be done.

A simple upgrade may cost you around $100 while some practitioners will charge you as low as $40.

However, some speakers may require complicated installation work that may last a whole day and push the cost to $300 or more. This could also include installing the amplifier and its enclosure. 

Still, some customers will pay more. It is not unheard of that a customer will pay $800 to $1000 for a high-level upgrade of their car stereo system.

To be on the safe side, I suggest purchasing all the sound system components from a dealer where the installation cost is included in the purchase price. 



How many speakers does a car have?

This is something that will also depend on the type of car. Some vehicles will have as few as two (on the front doors only) while others can have as many as 9 (3 at the front, 1 on each door, and 2 in the rear).

Others like the Bose panaray system in a caddy will have as many as 32…you heard me right!

However, a good car audio system will need just five speakers; a speaker on each door and maybe a 12-inch subwoofer in the trunk to provide the needed bass and a quality overall sound experience.

How do I Know if my Speaker is Blown?

how do I know if my speaker is blown?

How do I Know if my Speaker is Blown?

Handy Tips & Tricks to determine and solve this problem

Among the most frustrating things that can happen to your speaker is for it to blow out. Whether it’s a car speaker or the audio system in your home, a blown speaker produces an irritating sound that can suck the mood out of your living space.

If you suspect one of your speakers is blown, it is important to know how to diagnose the problem to find a viable solution. This is especially necessary before resorting to taking it for repairs or buying a new speaker.

But how can you tell that your speaker is blown? Below, I'll show you various things you can do to determine whether your speakers are blown or not.

There are numerous factors that should concern you about the state of your speakers. One of the easiest diagnoses is to simply listen to the sound output coming from your speakers. 

Signs of a blown Blown Speaker

Below are some notable causes for concern:

Sound Distortion

You should easily be in a position to distinguish if a speaker has got an issue from the sound it produces. Turn up the volume on your radio or audio system and listen for possible distortions in the sound quality, including a hissing sound.

For a blown speaker, the distortion tends to increase as you continue turning up the volume. The unmistakable fuzz” or “hiss” from a blown speaker will be hard to miss if you know what you are listening for.

It will be quite obvious that something should be done to remedy the state of your speakers. Fuzzy speakers are more often than not the consequence of loose or damaged voice coils.

Incomplete System Range

Another way to check your speaker system is to test its range. For this, you want to select one of your CDs or MP3 players with a full range of sounds, more so a strong bass. The next thing to do is play the CD at different sound frequencies and listen to the output from your speakers. 

If your speakers are whole, you should be able to properly hear the sound output from the highest to the lowest frequency. On the contrary, a blown speaker may not be able to produce any sound at high frequencies or a bass. 

This is a simple process that will take about five minutes to decipher the problem. 

Lack of Vibration

Vibration is a common thing that you can experience by placing your hand on the surface of a fully functional speaker. This is quite true for woofers and subwoofers. As a result, turning up the volume of your radio results in stronger vibrations on your speaker. 

One thing which indicates that your speakers might have blown out is that there are no vibrations, especially at higher volumes. The downside to this test is that it is only effective on larger speakers.  If you have a relatively smaller speaker setup, testing for vibrations with your palm may not work accurately. 

So, in such a case, you might want to experiment with the other methods mentioned earlier on. 

Also, when a speaker blows out, you are likely to notice the cone coming loose from its moorings. Eventually, when the speaker is completely broken, it may fail to produce the sound it once did when it was still brand new. 

Generally, bass speakers are the ones which usually blow out, although they may control other ranges. In such a situation, the thudding sound of the bass is replaced by a “rattling” noise or no sound completely.

Testing with a 9-volt Battery

testing a blowout speaker with 9v battery

This is another simple trick that will allow you to know the fate of your speakers in a matter of minutes. Simply disconnect your speaker by unscrewing it from its mount. Proceed to remove the wires from your audio system, and while still connected to the speaker, attach the wires to a 9-volt battery. 

You should be able to hear a “popping” noise coming from the speaker. This is an indication that the speaker is working just fine. However, if you don’t hear any sound, the speaker has probably blown out.

While conducting this test, be sure to practice safety when dealing with electrical equipment to prevent any possibility of injury. Don’t insert any tools into a speaker when it’s still connected to a power source. 

Resistance is Infinite

Another easy way of diagnosing your speaker’s performance problems is by checking its electrical response with the help of a standard multimeter. This way, you’ll be able to quickly determine whether your speaker’s voice coil or cone are busted. 

For a speaker that is functioning normally, its ohm reading on the device should be what it was rated at. But for a blown-out speaker, the observed resistance will essentially be infinite. Your speaker will also be blown if it has a reading of 2 ohms as opposed to the 4 ohms it is rated at.

Isolating the Affected Speaker

Finally, if you are having trouble figuring out which one among your speakers has issues, you can harness the fader system to isolate the various speakers. This will make it easy for you to detect the troubled speaker. 

You’ll also be able to tell whether it’s partly blown or completely blown. In both cases, you might have to consider replacing the speaker. If you don’t have a fader system you may need to have the speakers physically disconnected to test them. 

For this, you should seek the services of an auto service expert to handle the disconnection and reconnection of wires. 

How do I Know if my Speaker is Blown - Final Thoughts

The next time you suspect that your speakers might have blown out, the above tests provide an easy approach to diagnosing the fault in your stereo system. Remember that the sooner you realize what the problem is, the sooner you’ll arrive at a viable solution. 

The problem with continuing to use a faulty speaker for a long time is that it may end up degrading the performance of the whole audio system altogether. So use the above methods to know if it’s necessary to replace the faulty speaker.
