Causes of Speaker crackling at high volume

Speaker crackling at high volume happens when turning on and when turning off. It is a typical sound since they occur due to the expansion of power cables when the speaker is starting and contraction of the power cables when the speaker is shutting down.  Sometimes, the speaker makes crackling noise due to changes in the house’s temperature, which makes noticing the noises hard as the noise changes when the temperatures change.

Even though the noises do not harm an individual and cannot damage the rest of the machine, it is good to get rid of them if they are loud. However, since the noises are primarily normal, you can still prevent them by turning on the speaker gently but not switching all the power cables on for once or shutting them down for once since they can cause a louder crackling noise.

The article below discusses the possible ways of reducing crackling noise in the speaker, even if they are normal, and the causes of the speaker crackling at high volume.  Later are the frequently asked question and the conclusion at the end. Follow the guide to know the reasons why your television makes a popping noise.

Why is the speaker crackling at high volume

Causes of Speaker crackling at high volume

Interrupted current.

The primary cause of the speakers to make the crackling volume is the interrupted current. Speakers are in a design that their current moves in a linear motion depending on the audio signals. When there is an interrupted current, the signals move so that they will not be smooth, producing the crackling sound in the speaker when playing music. The interrupted current is in a form where the speaker’s signal is alternating. When the audio passes through the analog to digital signals, the amplitude reduces, causing the crackling at a high volume.

Faulty wires in the speakers

The speakers can have no problem with them, but if you check the wires, they can be having some issues that affect the whole working process of the system. The broken cables produce vibrations in the speaker, or sometimes the wires that come in contact with the other are of opposite charges that can cause a short circuit or shut down of the system.

To check if the wires are faulty, try playing music by disconnecting all the speakers and playing them one by one. If one has issues with music, replace the cables immediately.

Differences in temperature and humidity.

When the temperatures are high, the internal parts of the speaker get the warmth that continuous warmth causes them to expand. They make the crackling noise in the other way when the temperatures are low, the cables drastically contract due to change in their temperatures. The temperature changes affect the humidity level at that device such that when the temperatures rise, the humidity level lowers, while when the temperatures are low, the humidity level increases.

Starting the television.

The leading cause of crackling noise in the speaker is the starting process where the user is turning on the speaker, and then the power cables receive power which warms them. After heating the power cables, the power cables try to stretch due to their expansion which causes the crackling noise to occur.

Therefore you must not start the speaker at once when you want to use it to reduce the crackling sound but instead put on one point at a time like you can put on the power source from the wall then switch on the extension of which you will give the television cables to get warmer slowly then switch the speaker on after some time.

Resting speaker on uneven surfaces.

When using the speaker, some people place them on uneven surfaces to listen to what they want. However, putting the speaker on such surfaces makes the speaker be in a tilt position that increases the rate of crackling noise when using the speaker since most of its parts are not in their proper places.

It is advisable to use speakers on flat surfaces with rubber rather than on hard glass surfaces that can cause other noises apart from the crackling noise.

Dirty particles in the speaker surfaces

The speaker has vinyl that holds the static electricity when transmitting current. Therefore, when transferring the current and there is rust on the surfaces transmitting the rust, there will be crackling noise when the volume is high. Therefore, ensure you clean the parts in the speakers.

How to fix speaker crackling at high volume

Why is the speaker crackling at high volume

In some cases, crackling noise in a speaker is a source of worry to the speaker users, even though the noises do not affect the speaker and its parts. However, you can still find a way to reduce the cracking noise in your speaker to enhance comfortability in the house. Below are the ways of reducing the crackling noise.

1. Provide proper ventilators that enhance the room’s ventilation by opening windows and spaces to allow adequate air circulation in the house. High temperatures in a room cause expansion of most speaker parts since most regions have a plastic material that can quickly expand, making the crackling noise in the process.

2. Ensure the air vents in the air conditioner face a different direction sciencedirect facing provides much cool air into the speaker, causing them to contract or sometimes provide heating around the speaker, making the plastic cables expand, causing the crackling noise.

3. Place the speaker on a flat surface with rubber material that is spongy such that when the speaker vibrates when starting, you cannot hear crackling noise inside since placing the speaker in places that lack balance can increase the rate of crackling noise in the speaker as most of its parts displace their location. They keep fixing themselves when turning on the speaker.

4. After placing everything with the ventilations but the speaker still produces the crackling noise on high volume, consider switching off the speaker and opening the internal parts. Check the amplifier in the speaker; remember the amplifiers, in most cases, have the protection circuit that shuts the amplifier down when the power is getting in excess. Therefore, if the system speaker is cutting in and out on a high volume, check the amplifier’s issues with the protection circuit. Always test the speaker after every step before moving on to the following steps to confirm if the area is the cause of the problem.

5. Check the grounding wire that enhances the flow of electricity from the electrical devices. Remember, the electricity travels from the battery to the amplifier as the volume increases since the amplifier needs excess power. Therefore ensure the wires are well-grounded for proper flow of current in the circuit.

6. Ensure you clean the parts of the speaker by picking the debris in the surfaces and wiping the dust using specific detergents, and give them time to dry.  Maintain the practices responsible for the speakers to increase the durability of the product.

7. Consider testing the speaker to see if the steps you are trying are working with it. If the speaker still fails to work, check other parts that can cause the issues and rectify them. Ensure you work with all components and that they are okay to function in the speaker.

8. If the speaker is still crackling at high volume, consider consulting a technician to help you fix the problems since they have explicit knowledge of the speakers and how to work with them.

Frequently asked questions

A. Can a speaker make a popping noise?

Cracking noise is the same as popping noise since they occur due to similar reasons. When a speaker crackles, it means you are switching off the speaker to remove power from the devices. The crackling noise in the television is typical when starting or shutting down the speaker, just like the popping noise.  When you hear the popping noise in the speaker, check the parts of the speaker if they are all good and clean them properly. You can also avoid some practices that you know can cause damages to the speaker.


Speaker crackling at high volume is typical when switching on the speaker, switching off, or in the middle of the music. All this is because the speaker has metallic and plastic parts that, when they work together, make a crackling noise since there is expansion and contraction of the details. The parts contract sometimes and expand due to climate changes in temperatures and humidity. The article above shows the causes of crackling noise in the speakers when the volume is high.  There are also steps you can follow to solve the issue with the speaker.

Therefore, follow the guide on how to fix the crackling of the speaker and remember to read the manual book to identify the precautions to take while handling the speakers.  You can also ask a technician to help diagnose some other issues with the speaker if you fail to recognize them correctly. It is good to maintain the practices of keeping the speaker like cleaning it and keeping it in a good position to reduce some of its effects.
