Do you enjoy the deep, thumping bass of your favorite music? Do you feel like it is missing something lately? 

If so, there could be a chance that your subwoofer has blown. Don’t worry! We’ll show you how to tell if your subwoofer is blown and what to do about it.

Do You Have A Subwoofer That Is Not Working?

If your subwoofer sounds like it is blown, there are some simple ways to tell if the problem is with your amplifier or speaker. 

This article will give you step by step instructions on how to diagnose and fix this common issue.

You can save money by diagnosing the problem yourself instead of having to replace both components at once. 

Once you know what’s wrong, we recommend replacing the speaker first because it’s cheaper than buying an entire new amp! 

It doesn’t matter whether you have a home theater system or car audio system – these steps apply to all systems where bass frequencies are amplified through speakers. 

So let’s get started!

Signs of a Blown Subwoofer 

There are three main signs that indicate your subwoofer is blown: 

- crackling sound coming from the speakers. This could be a sign of a loose wire or damage to part of the speaker system itself.

- if you turn up the bass and it sounds like static, this means that your amp has been overloaded by too much electricity going through it at one time - which can cause permanent damage to both parts of the system! 

Don’t try turning down lower frequencies on your equalizer because you’ll still overload everything else. 

Turn off all electrical devices in your house before playing music again so you don’t send more power into them than they can handle! 

- If either one of these things happens while you’re listening to music with a lot of bass in it, you can be sure that your subwoofer is blown.

How to Tell if Your Subwoofer is Broken?

Some people say that the best way to tell if your subwoofer is blown is when you don’t feel any bass coming from it. 

But what about when you can hear the bass? If your sound system has a lot of bass, but there’s no deep rumble or vibrations, then something might be wrong. 

A blown woofer will often make noises like buzzing, humming, squealing, and rattling. This means that it’s time for an upgrade! 

The sign of a bad woofer isn’t always easy to spot until it’s too late. 

For example: every once in a while have this one friend who goes out and buys expensive speakers or electronics. About a month later, he comes back and tells that the speakers are blown. 

The reason why it’s so hard to tell if your subwoofer is broken or not is because there might be some things you aren’t aware of. 

There could also be some signs that you just haven’t noticed yet! 

For example: if you have a speaker that doesn’t produce any bass, then it could be because your subwoofers are blown. 

This is just one of the signs that there’s something wrong with your woofer! Keep reading to learn more about how to tell if a subwoofer is broken or not. 

How do I Know My Woofer isn’t Working Properly?

The first step in figuring out why your speakers aren’t hitting as hard as they should is checking for damage on the outside. 

If you see anything weird like dents or pockmarks along either side of the cone, those could indicate an internal problem within the speaker. 

Another thing to look at would be where wires plug into the woofer. If that connection is loose, then it’s going to affect how well your subwoofer works!

How Can You Fix a Blown Subwoofer?

If you have come across the above-listed signs of a blown subwoofer, then there is no need to worry about your subwoofer anymore. You can fix it easily by following some simple steps, here are they:

Unplugging the Amp:

Unplug the Amp from the wall and unplug all cables from both ends of the speaker. 

Removing the screws:

Remove any screws securing the grille or front baffle to the cabinet and remove them if possible (if not possible then just be careful). 

Searching for damage:

Inspect for signs of damage such as broken parts, cracks in wood or plastic parts and other things that might indicate an electrical problem like frayed wires or scorch marks on wiring insulation. 

Thumbing sound:

Place your hand over one end of each cone and gently push down while doing so with your ears pressed against the cabinet to listen for any rattling or rubbing noise.

If your subwoofer is blown then you will hear a “thumping” sound when applying pressure (this can occur even without touching it). 

Checking the bolts and screws:

Check that all screws and bolts are tightened securely, if not tighten them up by hand first before replacing them with an adjustable wrench.


Reconnect all cables and power back on, turn volume down low and test out speaker again. 

Final Thoughts:

After going through the above details, you are now able to find out if your subwoofers are blown or not. Furthermore, now you can also fix them following the above-given simple steps as well.

If these steps don’t fix your problem, consider taking apart and reassembling the woofer housing in order to make sure nothing was loose during shipping; however, keep in mind this may void any warranty so proceed at your own risk!
