How To Fix Crackling Car Speakers? Step By Step Guide

Car speakers can become crackly for different reasons. One of the main reasons for a speaker to crackle is when it’s plugged into an amp with a poor connection. Another reason why car speakers will often sound crackly is that they could have been damaged and this would mean that small pieces can get bent or broken and these would shift around inside the speaker, which would then cause a crackling noise you might hear through your car’s audio system if you’re listening to audio at high volumes. Also, speakers will sometimes become crackly when they’re plugged into too powerful an amp and the cone within the speaker can’t handle it. This causes damage to the voice coils which will then produce cracks in the sound output of your car’s speakers.

One of the most common problems faced by car owners is crackling car speakers. This blog looks at the causes of crackling car speakers and the different methods to fix them.

What causes Crackling car speakers?

One of the major causes of crackling car speakers are loose connections and damaged speakers. Wires that have been damaged due to misuse, time, or corrosion can crackle your speakers. The wire, terminals, and speakers all need to be in good working order to remove the crackling sound.

Imagine you are driving through the suburbs, listening to your favorite music, when from the speakers you hear a horrendous screeching sound.

You’re not alone, many people are wondering what causes their car speakers to crackle and how to fix it.

Why are my car speakers crackling?

The ‘cracking sound’ our speaker gets is effectively the sound of resistance running through the wire connections. There are two main causes for speakers’ connection to be bad:

  • Torn speaker wires. Old car audio installations tend to feature cables that are tightly wound around the places in a vehicle where doors are to be opened, or closed. This can over time damage the wiring beyond repair, since it gets such a heavy workout daily. What is worth mentioning here is that when repairing older car entertainment systems of this kind, there are high-quality OFC cables available on Amazon.
  • Damaged connectors. Radio harnesses are usually in good condition and rarely damaged since they’re packed away and protected. On the other hand, common connector problems occur with speakers because they tend to shift when the speaker wire rubs against them. For example, car speakers mounted on rear decks (traditionally called a kick panel) are subject to lots of movement over time, which causes wear on the twist-lock connectors that secure the wires to an amplifier or radio chassis. It’s best if you use strong FLIX technology spade connectors.

If both wires of the speaker and the connectors are in good condition, and if the speaker is not covered in the dust then another reason for this issue is that the voice coil may be damaged.

Putting the coil on top of the magnet generally tends to reduce the crackling noise. Various other tactics have also been proposed by experts in order to arrive at a satisfactory outcome.

This lightning contact creates a shortcut that lasts for no more than a fraction of a second — but it is enough for the expression “to crackle” to come about.

Here are some common reasons why the voice coil can be out of the position

  • When the speaker’s cone or suspension was repaired, and then was put back together along with the voice coil being placed in a position that rubs against the magnet.
  • If the voice coil was replaced, and the new one was placed incorrectly.
  • Speaker may be faulty by the manufacturer.

Speakers will also crackle if they are in need of a clean-up. If we do not properly clean our speakers, it is common for them to emit electrical noise or static. This is due to the buildup of dust, which causes a short circuit which in turn plays havoc on whatever audio device you’re using. Just make sure you keep your speakers and any audio devices free from dust and grime to prevent this from occurring!

Amplifiers can produce signals at a low volume without experiencing problems, but when many car speakers crackle at high volumes, it can be a sign of damage to the amplifier.

If you have an issue with pre-outs, it may need to be repaired or even in the worst case replaced depending on the damage.

Can crackling damage car speakers?

The speaker crackled and it’s the worst thing that can happen, you ask? The answer is no. You see, when a speaker crackles its first reaction is to put off electrical pulses called “spikes” which overload your system or even break your speaker permanently. The first step to take in this situation is to replace the damaged piece of equipment and try to figure out what caused excessive current through the system. You see, one of the causes as we already mentioned above, is an interrupted current – but there are many more such malfunctions that might be located in different places.

Mechanical damages are often something that comes along with unstable voice coil movements.

An electrical malfunction with the speaker could mean that the voice coil has been damaged or blown.

If you hear popping or crackling sounds coming from your speakers, stop using them until you can find the source of the problem. You could cause serious damage not only to your speaker but to the car’s entire audio system too.

How to fix crackling car speakers?

Most car speakers are not worth repairing because the expense of having professionals repair them is too high for their age and the amount of time they’ve lasted. Repairs by professional companies can exceed the cost of what you paid for your car, sometimes even more.

We regularly fix either unique or expensive speakers that are irreplaceable. Unfortunately, some of our clients prefer to go with a replacement that is difficult to find.

Repairing the voice coil is pretty complicated due to all of the things that come into play during this process. If you’re not an expert or have no experience with electricity and audio systems, then I’d definitely steer clear of this job altogether because it’s one that could turn out to be more difficult than anticipated if you’ve never worked on a speaker before. While repairing this component may look easy in some respects, there are so many things involved that you might want to try buying a new speaker from your local store instead of going through all the trouble of trying to repair it by yourself.

It really irks me when there are issues with my home speakers – mainly because I know that I bought a new component, gave it a full cleaning, and tested my repair job by hooking it up to an MP3 player. But even after all that, it still sounds murky or distorted and I wonder why this…

Cracked speakers can be a huge nuisance, especially if you feel as though the music is an essential part of your day-to-day life. How can you fix them without having to replace your entire speaker set? Although cracking open your speaker and repairing it yourself may sound tricky, it’s actually quite easy and doesn’t require expensive tools or any particular skills.

Listening to music while driving is an excellent way to relax and escape the vehicle’s surroundings when we have nothing else to distract ourselves with. However, nothing can replace good old relaxation and one should not allow their mind to wander completely at any given moment. Without focus, there is a risk of making mistakes. That is why it is recommended that one keeps a handle on any potential dangers ahead by taking simple precautionary measures like wearing seat belts etc.

If one is to listen to music on their car speakers, they’re likely to experience something called speaker crackling. If a person has this problem while playing the music loud, turning it down may serve as an initial remedy, but if one continues to hear popping or cracking noise at moderate volumes, there may be an issue with other factors such as the volume level of the recording or even the type of system setup depending on whether it’s factory-installed or added-on later.

Check the Speaker Wires streaming from the amplifier or radio to the speaker

There are many places you need to check for signs of damage when it comes to speaker wires, not just at the ends. You have to look for mechanical damage in the shielding, or corrosion along the wire’s surface which can affect signal quality. Of course, the proper enclosure is important as well, and making sure all connections are stable will prevent any harm from coming to your valuable loudspeakers.

For all cars, speakers take and Use High-quality Pass filters

Turning on the correct filters will stop too much bass from hitting the car speakers which might cause them to be damaged. Speakers in cars are usually not designed to produce strong low frequencies and forcing too many lows can put a strain on them. If you want bass, then one of the simplest solutions would be installing a subwoofer, or adjusting the frequencies going to door speakers so that they don’t put out any significant bass to avoid stressing them.

To Fix Crackling Car Speakers Increase the Bass at Low Volume and Reduce the bass at High Volume.

When you listen to loud music, it’s important to pay attention not just to the bass but also to the treble. Our ears hear a lot of frequencies simultaneously, so if we turn up the bass on our music then it’s advisable that we slightly lessen the treble, otherwise our ears will be hurt from listening to too much bass as well as having that crackling sound.

Avoid Bass Boosted Music

Too much bass can be harmful to the quality of your music. If you’re giving a concert it can quickly become overpowering, but otherwise, this isn’t something that should be an issue. Music with a lot of basses will particularly stress your speakers and other sound systems far more than usual, and unless they’re made from high-quality materials (like those from Lanzar), it could even lead to permanent damage!


If you’ve ever noticed a crackling sound coming from your car speakers, you’re certainly not alone. This issue can be caused by a number of different factors, but it’s typically an issue with the car stereo. If you notice this crackling sound, it’s very important that you contact your local car speaker repair technician as soon as possible.
