Your subwoofer has stopped working! You have no idea why, and after checking everything, you are left with no sound at all.
Unfortunately, there are a lot of reasons why your subwoofer suddenly stops producing sound, and fixing the problem can take some serious work.
This guide will help you identify the problem, and how to fix it. A subwoofer can make a speaker system sound deeper and richer. However, if your subwoofer isn’t working, you should learn how to fix it!
What Causes a Subwoofer With No Sound?
If you have a subwoofer that does not provide any sound, it is likely that one of the speakers in your stereo system or TV is not set up to use it.
To ensure that the subwoofer is able to provide sound, increase the volume level on the subwoofer and make sure that the speaker settings on the stereo system or TV are set up properly.
How To Fix A Subwoofer With No Sound?
A Subwoofer, also known as a woofer, is a speaker that is designed to produce very low frequencies. Subwoofers are essentially small drivers that are capable of producing frequencies up to 20 Hz, which is the lower limit of the human ear.
By producing lower frequencies, the sub-woofer provides the lower frequencies that are otherwise missing in most music recordings.
A subwoofer is an integral part of any sound system, but occasionally they may stop working. This is usually due to the subwoofer running out of power. Fortunately, there are several things that you can do to fix the problem:
Reset the subwoofer:
The simplest method to use when trying to fix a subwoofer with no sound is to unplug it and plug it back in. This usually solves any issue associated with the subwoofer.
Check all connections:
Another method to use when trying to fix a subwoofer with no sound is to disconnect it from the amp or receiver and connect it to a different amplifier or receiver. If the subwoofer works fine with a different amp or receiver, then the problem is with the amp or receiver.
Check the volume or power:
If the subwoofer is working but has no sound, then the volume may be set too low. To fix this problem, ensure that the volume of the amp or receiver
Try to Increase the volume Of Subwoofer:
Another method to use when trying to fix a subwoofer with no sound is to disconnect the subwoofer from the amp or receiver and try to increase the volume of the subwoofer. If the subwoofer volume is turned up high, then the problem may be with the amp or receiver.
Check the equalizer settings:
If the subwoofer has a remote control, then you can use the remote control to adjust the equalizer settings on the amp or receiver. If the subwoofer volume is turned up high, then the problem may be with the amp or receiver.
What are the symptoms of a bad subwoofer?
There are many reasons why your subwoofer might not be working. Maybe it was out of juice, but after a while, it should start working again. However, sometimes, the subwoofer is defective or did sustain damage.
The solution to this problem is buying a new one or hiring a trusted professional to repair it.
Bad wiring and connections are common causes of a faulty subwoofer, with some of the most common ones being loose connections, open fuses or blown fuses, or bad capacitors.
A subwoofer that is not receiving power or has no sound because the connections are loose, or if it has blown the fuses or capacitors on its circuit board, the most common solution is to disassemble the subwoofer further and repair or replace the damaged parts.
Causes of a bad subwoofer:
If you are having problems with the sound quality of your subwoofer, there are a few different things that you should look at.
You should start by making sure that the subwoofer is connected correctly to the amp. Your amp should have a mini jack or RCA connections, and you will want to make sure that both the subwoofer and amp are plugged into the same outlet.
Next you should check the volume level on your amp. If you’ve set it to maximum, it is probably not loud enough for the room. In most cases, the amp, subwoofer and speakers should be set to the same volume level.
If both of these seem fine, there could be a problem with the wiring between the amp and subwoofer
How to test subwoofers before you start replacing them?
Sometimes your subwoofer may be defective and not even producing any sound but still showing some power.
- You can try checking for stuffed cones, corrosion or internal terminals but many times they are just bad, and need to be replaced.
- Check and make sure there is no blown fuses, then disconnect all cables and unscrew the woofer plate from the crossover.
- Check the capacitance to see if you have power or not. If not, check the fuse for continuity.
- Turn the amp on and dial all your controls to the maximum setting.
- Then, connect all cables and turn on the amp or receiver. When your sub starts making some noise, slowly adjust the knobs back and forth until you hear your sub stop making any sound. If you find this, then that is your crossover setting.
- If not, then try adjusting your crossover some more until you find your sub stop bass and stop making any noise. Then, place your sub back on the stand.
What to expect when fixing a subwoofer?
Imagine this scenario: you turn your subwoofer on, and it doesn’t even make a sound. This is not uncommon, as there are several possible causes.
The most obvious cause is a blown speaker. This happens when the speaker is damaged physically or magnetically. Other causes include blown capacitors, blown fuse, dirty subwoofer, and defective wiring.
If the subwoofer has an internal speaker or a satellite speaker, then you only need to replace the speaker. If the subwoofer speaker is external, then you can remove the entire subwoofer and replace it.
To determine if a speaker has blown, you simply turn on your subwoofer; if the speaker is working, then that means that it’s blown. If, however, the speaker is blown, then you should either replace it or fix it.
What to look for when fixing a subwoofer?
Fixing a subwoofer with no sound is easy. But if you’re not sure how to, here’s a few pointers.
Tip #1: Check the user’s manual.
The user’s manual will tell you what and how to change.
Tip #2: Know what to replace.
Subwoofers are complex mechanisms that have many different parts inside of them, but two of the main parts that may need replacing are the subwoofer itself and the amplifier.
Tip #3: Ensure that you have the right part number.
Sometimes, the subwoofer and its components can have different names, and this can confuse things. If the manual doesn’t have the right part number, you can call the manufacturer or consult online to get some additional information.
Tip #4: Test it after you’ve fixed it.
Yes, this means you will have to unplug the subwoofer again. But then you need to test it again to make sure that everything is working properly.
