This is a very common problem with all subwoofers but most of the time people don’t know how to solve it. I found a simple solution that works well and does not require a big expense.

Many times subwoofers produce a loud buzzing sound when they are turned on and off because there is a ground loop between the amplifier output jack and the subwoofer itself. This is usually caused by either poor construction or a bad connection between the subwoofer’s amplifier and the speaker terminals.

It’s easy to solve this problem. Simply run an audio cable from the subwoofer’s input to your main amplifier. In this way, you will prevent ground loops in your system and eliminate the annoying sound.

But if the Subwoofer has other problems then do not worry. We will tell you how to resolve it in this article. So let’s start the discussion.

What Causes This?

Following are some common reasons due to which the subwoofer creates noise.

Poor Construction:

Subwoofers are usually connected to the amplifier using RCA connectors. Usually when there is a connection error between the subwoofer and the amplifier the two things are not perfectly in line. This can result in a buzzing sound.

The Amplifier Output Jack is Damaged or Dirty:

If you notice that your amplifier’s output jack is damaged or dirty this could cause buzzing sounds in the system.

Low-quality Speaker Terminals:

Subwoofers have poor speaker terminals because of low-cost manufacturing standards. You need to replace the speaker terminals with good-quality ones.

Ground Loop:

A ground loop occurs when there is a direct connection between the amplifier output and its speaker terminals without an audio cable. This can happen due to either the amplifier being installed backward or when the cable is too long or loose. This is one of the most common reasons for buzz in subwoofer systems.

Poorly Installed Subwoofer:

The reason for buzzing sound in the subwoofer is usually something that was not considered while installing the subwoofer. Therefore, it will take a little time to figure out what the problem is. It is also possible that it is caused by something else which was overlooked at the same time. The buzzing noise could be caused by a damaged output jack or a bad connection between the amplifier and the subwoofer.

Do You Need A New Subwoofer?

I’m sure many of you have been experiencing sound issues with your subwoofer. Maybe it makes a weird buzzing or buzzing noise when turned on. The problem is caused by the fact that there is a ground loop between your subwoofer’s amplifier output jack and the speaker terminals.

If you haven’t seen this issue before, it’s probably because you’ve never had a subwoofer connected to your amplifier before. The simple solution to this problem is to run an audio cable from the subwoofer’s input to your main amplifier. In this way, you will prevent ground loops in your system and eliminate the annoying sound.

 It means you do not have to buy a new subwoofer when the old one makes noise. But still, if you can not resolve the issue you can see the easy tips that we will discuss in this article.

What To Do When Subwoofer Make Noise:

This article will provide some tips on how to deal with this problem and help your subwoofer perform to its full potential.

STEP 1: Make Sure the Subwoofer Is Unplugged First

The first step to dealing with the clicking sound is to make sure your subwoofer isn’t plugged in. Sometimes people turn their speakers on while they are still plugged in, so they might be playing through their car or home audio system instead of their external speakers.

Turning the subwoofer off and on again should usually fix the problem.

STEP 2: Look for Clogged Ports

The second way to fix the issue is to look for any connections between the port and the speaker that could cause it to stick. This can include things such as dust or buildup that could clog the connection.

STEP 3: Try to Disconnect the Speaker Port

If the problem persists, you will need to unplug the port. Unfortunately, it can be quite difficult to remove the connectors, so this step might take some time.

STEP 4: Clean the Port with a Q-Tip

One final tip is to use some compressed air to clean the port. A high-quality shop vac would probably be most efficient, but you could use a compressed air canister as well.

Step 5: Reinstall the Subwoofer

After you have completed the steps above, you should be able to start using the subwoofer again. If it still doesn’t work, then the problem is likely at the speaker level. This means that your new speakers are faulty. To fix the problem, take your speaker back to the manufacturer for repair.

Wrapping It All Up!!! 

There may be an issue with your woofer. If you turn your subwoofer on and you hear a loud clanking sound, this is usually a sign of loose connections or a faulty unit. You can check to make sure the subwoofer is connected correctly using a subwoofer connection diagram if you have one.

If it’s not the case, you can make sure the amplifier is working correctly by switching off and on the power supply, and then testing again.

You may also want to disconnect the power supply for a couple of minutes and reconnect it, and then try again. If it is still making noise, you may have to replace the power supply.
