Why Does My Subwoofer Pop? (Causes & Solutions!)

When things get really loud, it can really push the limits of the human hearing threshold. Just because it pushes these limits doesn’t mean it’s necessarily great for your ears, however.

Over-blown music, particularly bass, can get annoying over time, and subwoofers can make the experience even worse. In this blog post, we’ll explore some of the reasons why your subwoofer may be popping and show you how to address these problems.

Why Does My Subwoofer Pop?

The most common reason for a subwoofer to sound unpleasant occurs when it is not powered with sufficient current.

When a cable is plugged into a powered subwoofer and plugged into a powered amplifier, the amplifier automatically powers both components.

However, if the cable is not long enough, the amplifier will not power the subwoofer. In this case, the subwoofer will not sound pleasant because there is not enough power to reproduce the low frequencies in music and movies.

In order to avoid this problem, look for an amplifier that automatically powers the subwoofer as well as any other connected components. This will happen when the cable is plugged into the amplifier.

What causes a subwoofer to “pop”, and how to avoid it?

Subwoofers are key to getting a powerful bass sound out of your system, but can become problematic if they begin to “pop”.

A subwoofer is a box-shaped component that sits below your TV or integrated home theater system.

The subwoofer plays a crucial role in reproducing low frequencies in movies, music, and sports broadcasts. However, if it becomes distorted, it can create a low-quality audio experience.

The most common causes of a subwoofer popping are miswiring and the buildup of heat inside the box.


Improper wiring can cause a subwoofer to pop. A subwoofer should have its negative (-) cable connected to its negative terminal and its positive (+) cable connected to its positive terminal.

Heat buildup:

If a subwoofer isn’t well-ventilated, it can produce excessive heat. When this happens, dust can settle on the components of the subwoofer and this dust can block airflow and cause it to pop.

What you should do:

If you notice that one of your subwoofers is beginning to pop, the first step is to identify where the popping is coming from.

If the popping is coming from one or multiple components inside the Subwoofer placement: If placed too close to walls or other structures, the subwoofer may rattle or vibrate.

1. Low ohm wiring

If loud bass responses require higher ohm wiring, then it can be very difficult to work with.

If subwoofer wiring is crossed or shorted to terminals, it can burn the subwoofer and create dangerous levels of heat.

Subwoofers require a certain amount of power in order to produce loud bass sounds. If the subwoofer is not connected to a receiver or amplifier with sufficient power,

Possible causes and solutions for subwoofer popping problems:

Subwoofer popping can be really annoying. It usually happens when you are listening to a song with a lot of bass or when you are watching a movie.

The sound that pops out can be so loud that it even scares you. Here are possible causes and solutions to help fix the problem:

1. Use too much bass

If you turn on your music with too much bass, then the subwoofer is pushed beyond its limit and it pops out.

2. Poor amplifier design

If the amplifier is poorly designed, it can cause the subwoofer to overwork and cause it to pop.

3. Poor subwoofer placement

If you place the subwoofer too close to a wall, then it can react more violently to the sound coming through. Your subwoofer may struggle to reach the intended sound level, causing it to overwork and cause it to pop.

Common subwoofer problems outside, inside, and in between:

Subwoofers have become an integral part of most home theater systems. They process bass frequencies, which make you feel the “boom” from heavy bass instruments.

While subwoofers are useful, they can also introduce some common issues. If you’re experiencing any of these problems, you might need to adjust the settings on your subwoofer.

How to keep your subwoofer from popping?

The subwoofer is an integral component of any sound system, and even the smallest of rumbles can cause the whole thing to vibrate.

If, however, the subwoofer is out of alignment or improperly supported, it could cause some strange rattling or popping sounds.

Common subwoofer problems include:

Low ohm wiring: Louder bass responses require higher ohm wiring, which can be difficult to work with. If subwoofer wiring is crossed or shorted to terminals, it can burn the subwoofer and create dangerous levels of heat.

Insufficient power: If the subwoofer is not connected to a receiver or amplifier with sufficient power, it will not perform as designed. This means it will not generate the appropriate bass levels or may be blown by too much power.

Inadequate cooling: Depending on the power source, the subwoofer may overheat if inadequate cooling is not provided.

Subwoofer placement:

If placed too close to walls or other structures, the subwoofer may rattle or vibrate.

Keeping Your Subwoofer From Popping:

1. Keep subwoofer wiring straight and away from metal objects

Subwoofer wiring should be straight, and away from metal objects.

2. Use a subwoofer amp

Many subwoofers come pre-amplified, but for more powerful bass, use a subwoofer amp.

3. Use high-quality speakers for low bass

For lower bass, use high-quality speakers. They generate lower frequencies and have less distortion.

Why does my subwoofer pop at high volume?

When you crank up the volume on your subwoofer, you might notice a loud popping noise. This is caused by the subwoofer’s voice coil rubbing against the magnet.

The voice coil is what produces the sound waves, so when it rubs against the magnet, it creates a vibration that can be heard as a pop. There are a few things you can do to prevent this from happening. 

First, make sure that the subwoofer is properly mounted. If it’s not mounted securely, it can vibrate and cause the popping noise.

Second, try using a lower frequency setting on your subwoofer. This will allow the voice coil to move more freely and prevent it from rubbing against the magnet.

Finally, if you’re still having trouble, you can try using a smaller amplifier power supply.

Why Does My Subwoofer Pop When I Turn It Off?

It’s a common problem: you’re enjoying your music, and then you turn off your subwoofer and suddenly there’s a loud pop. Why does this happen?

There are a few possible explanations. One is that the audio signal before the amp is shutting off before the amplifier(s) turn off. This can cause a brief moment of distortion that can sound like a pop.

Another possibility is that the speakers are still trying to produce bass frequencies even after the power has been turned off. This can cause them to vibrate, which can create a popping sound.

Finally, it’s possible that there’s simply a buildup of dust or other debris inside the subwoofer that’s being dislodged when you turn it off. This is usually not a serious problem, but it can be annoying nonetheless.

Why Does My Wireless Subwoofer Pop?

There are a few reasons why your wireless subwoofer may be popping. One reason is that the pre-out jack is not being muted.

This can be easily fixed by going into your settings and muting the pre-out jack. Another reason for the popping sound could be that the subwoofer is not receiving a signal from the receiver.

This can be fixed by making sure that all of the cables are properly plugged in and that the receiver is turned on. If you are still having problems, you may need to contact your manufacturer for further assistance.
