Subwoofer Stopped Working But Amp Is On: Why & What To Do?
If your subwoofer stopped working while the amp is on, you are not alone. We know it cannot be very clear when something like this happens. That is why we have put together this guide to help you troubleshoot and fix the issue as quickly as possible.
Some possible causes of this problem are failed driver magnet, magnets close to the speaker, inadequate power, failure of the cone seal, and short circuits.
You can easily fix this problem with a little knowledge and the right tools. By following our guide, you can avoid any potential damage from trying to fix things yourself without knowing what you are doing.
Why Are My Subs Not Working
There could be several reasons why your subwoofer stopped working but amp is on. It is important to troubleshoot the issue to get your subs up and running as soon as possible. The following are some potential causes for why your subs are not working:
Failed Driver Magnet
A failed driver magnet can cause problems with a car’s sound system, from making it difficult or impossible to turn the volume up or down to distorting the sound. If you are experiencing problems with your car’s audio system, it is worth checking to see if the driver magnet is functioning properly. If it is not, replacing it should solve the issue.
Magnets Close To The Speaker
If you are experiencing problems with your car’s audio system, one possible culprit is the proximity of magnets to the speaker. Magnets can distort the audio signal, resulting in lower-quality audio. If this is the issue, you may be able to fix it by moving the magnets away from the speaker.
Inadequate Power
There are a few things that can happen when it comes to inadequate power. In the case of car subs, one of the most common issues is that they simply will not work at all. It is because the power requirements of a car subwoofer are much greater than those of most other speakers in a car.
To properly power a car sub, you need an amplifier, a battery vs. capacitor car audio specifically designed to do so. Most factory-installed amplifiers are not up to the task, so if you are using one of those, your woofer will likely not work very well.
Failure Of The Cone Seal
The cone seal’s failure is the most common reason that a car’s subs might not work. This problem occurs when the seal between the cone and the speaker housing fails, resulting in a sound loss.
In most cases, this is caused by age or wear and tear, but it can also be due to damage. If it fails, the speaker’s sound will escape from around the cone rather than being directed towards the listener.
It can cause problems, including reduced sound quality and volume, and even make the subs completely inoperative. If you are experiencing any of these issues, you must change the cone seal.
Short Circuit
A short circuit is an electrical problem when something causes a wire to touch another. This problem can create a fire hazard, and it can also damage the electrical equipment.
In the case of a car sub, a short circuit can cause the woofer to stop working. However, the amp may still be on, creating a fire hazard.
If you experience this problem, it is important to take your car to a mechanic to have it fixed. Short circuits can be dangerous, and you should not ignore them.

How To Fix A Car Subwoofer With No Sound
There are some ways to fix a car subwoofer with no sound. We will walk you through the process step-by-step, so even if you have never worked on a car sub before, you can get the job done in no time.
Check If The Subwoofer Is Properly Plugged In
If your sub is not producing any sound, you should first check to make sure it is properly plugged in. Ensure the power cord is securely plugged into the outlet and the cable from subwoofer is connected to the appropriate port on the receiver or amplifier.
If everything is plugged in correctly and you’re still not getting any sound, your equipment might have a problem.
Check To See If The Wires Are Frayed Or Broken
A frayed or broken wire can cause many problems, including sound loss. If you find that one or more of the wires are frayed or broken, you’ll need to replace them.
You can purchase replacement wires at most auto parts stores. Be sure to get the right size and type of wire for your particular car and subwoofer system. Once you have replaced the wires, test the woofer again to ensure it’s working properly.
Check The Fuse Box For A Blown Fuse
If the fuse is blown, you will need to replace it. To do so, remove the cover of the fuse box and locate the fuse for subs. It should be a large, fat fuse. If blown, replace it with a new fuse of the same rating.

Try To Reset The Subwoofer
If your subwoofer is not producing any sound, you may be able to fix the issue by resetting the subwoofer. First, ensure that the woofer is powered on and that the correct input source is selected. Next, locate the power button on the sub and press it for five seconds. The woofer should now be reset and should start producing sound.
Check The Settings On The Amplifier Or Head Unit
If your subs aren’t producing sound, you should check your amplifier or head unit settings. Ensure that the woofer is turned on and the volume is turned up. You may also need to adjust the crossover frequency or equalization settings to get the best possible sound.
Take It To A Professional Car Audio Specialist
If the above methods don’t work, you should take it to a professional car audio specialist. Car audio specialists have the knowledge and experience necessary to get your car’s audio system working properly again. They will be able to diagnose and fix the problem quickly and efficiently.
How To Check If Subwoofer Is Working
If you’re unsure whether your subwoofer is working, there are a few ways to check.
Check The Subwoofer’s Visual Indicators
The first way to check if your sub is working is by checking the visual indicators. Most subs will have a power indicator light that will let you know if the woofer is receiving power. If the power indicator light is not lit, then the subwoofer is not receiving power and is not working.
Listen for Sound
Another way to check if your woofer is working is by listening to the sound. If the subwoofer is connected to a stereo receiver, turn on the receiver and play some music. If you don’t hear any sound from the subwoofer, it is not working.
Check the Subwoofer’s Inputs and Outputs
If you’re still unsure whether your subwoofer is working, you can check the subwoofer’s inputs and outputs. Most subs have a line-level input and output. You can use a test meter to check for continuity between the subwoofer’s input and output. If there is no continuity, then the subwoofer is not working.
If you have followed all of these steps and your car sub still isn’t working, it may be time to contact a professional for help.
Frequently Asked Questions (FAQs)
Why Isn’t My Amp Getting Power?
There are a few things you can check to try to diagnose the problem:
- Check the fuse: The first thing you should check is whether or not the fuse has blown. If it has, then replaces it with a new one.
- Check the wiring: Another possibility is something wrong with the wiring. Inspect it for any loose connections or breaks.
- Check the ground connection: It’s also possible that the ground connection is loose or not connected properly. Inspect it to make sure it’s secure.
- Check the power supply: Finally, make sure that the power supply is working properly. If it’s not, then you’ll need to replace it.
If you’ve checked all of these things and the problem persists, then you may need to take your car to a mechanic to have it looked at.
How To Repair Car Amplifier No Sound?
If your car amplifier is not producing any sound, there are a few things you can do to try to fix the problem.
The first thing you should do is check the fuse and make sure it is still in working order. If the fuse is blown, replace it with a new one.
You should also check to ensure all cables are properly connected and that no debris or obstruction is blocking the sound from coming out of the amplifier.
If everything appears in order, you may need to take your amplifier to a professional for repair.
How To Check If My Amplifier Works?
First and foremost, it is important to determine if the amplifier is the source of the problem. To do this, temporarily connect the speakers to another amplifier or powered speaker and see if the same issue persists. If it does not, the amplifier will likely malfunction and should be serviced.
You will likely need to have your receiver serviced if it does not. If it does, one or more of your speakers may be at fault. In this case, try replacing them one at a time to see if that fixes the issue.
