How To Fix Car Speakers Crackling

By: Editorial Team

Imagine enjoying your favorite music while driving in pleasant weather when suddenly your speakers begin to make a bothersome cracking noise.

Many people question why and how to prevent vehicle speakers from cracking since it occurs so often.

The primary cause of car speaker cracking is a faulty connection between the speaker and the amplifier. Damaged voice coils that touch the magnet may also cause the speakers to crackle. Additionally, speakers powered by a solid amplifier may crackle when the voice coils attempt to pull the cone beyond its breaking point.

The best advice is to avoid having your car’s speakers start to crackle. You may need to start the repair by changing wires and connections since a faulty connection is a frequent source of this problem. You may find these essential components of any automobile audio by clicking the links on

We will go over these reasons in more depth in the following article, as well as how to fix speakers that are cracking and how to stop automobile speakers from cracking.

4 Causes Of Car Speakers Crackling Or Popping

Before considering the remedy, you first understand why your vehicle speakers are popping or crackling. This problem has several causes, including the following:

  • Torn wires might be one cause of cracking automobile speakers. If the cables are exposed and lying about in your automobile, it’s pretty easy to see. However, the wires often rip in constricted areas like the door’s corner. Additionally, the included wiring for the speakers isn’t of the highest quality. Consequently, they are readily prone to rip, which results in the speakers cracking.
  • The speakers’ connections may sometimes come free. The speaker cables wrapped around the door and the car’s continual movement are potential causes of this. The crackling sound you hear results from the noises being unable to properly transfer due to the unsecured connections.
  • A broken voice coil is the most significant cause of a crackling speaker. It doesn’t have to be constantly damaged; simply voice coil displacement might result in this problem. There are various causes for displacement. It’s possible that the new voice coil you installed didn’t get put in the right spot if you replaced the old one. So, when this occurs, a spark between the magnet and the speaker’s voice coil may result in a cracking noise.
  • When you connect your automobile speakers to a malfunctioning pre-amp or amp, they may start to crackle. Typically, a broken amp can’t even power the speakers, but sometimes, you get this type of problem when it can. By turning up the volume, you can verify it. Your automobile speakers may have a faulty amp if turning up the volume causes them to crackle.

There aren’t many things that might cause your automobile speakers to crackle other than these causes. The actual question at this point is: Can you resolve this problem? Yes, is the response.

Even though cracked speakers are already an indication of speaker damage, many techniques exist to repair them. That will, however, mainly rely on what is causing the crackling problem. Let’s examine the remedies you ought to attempt in each circumstance.

How Can Crackling Sound Damage The Car Speakers?

The speaker can already be damaged if it is making a crackling noise. If not, it could result in an interrupted current that overstresses the voice coil and finally harms the mechanical or electrical component of the speaker.

  • Broken or fractured cones with unpredictable voice coil motions that have been overstretched are linked to mechanical defaults.
  • In contrast, the voice coil is broken or blown is what causes the electrical harm.

As a result, try to avoid using your speakers if they start to make a cracking noise until the problem has been resolved. If not, you risk damaging the speaker and other automobile audio system components.

How Do You Fix Crackling Car Speakers?

You must seek a remedy to the issue after identifying its root cause.


1. Fix The Connection Between The Amplifier Or Radio And The Speakers

If the wire connections between the amplifier and speaker are what’s making the noise, the first thing to do to stop crackling from vehicle speakers is to repair them.

It’s possible that a youngster or animal moved the wire around a lot in the past.

Turn off the system and unplug the speaker cables from the amplifiers to test this.

Try now to start the vehicle.

If the noise is still there, it may be radiating into the cables.

Reposition the wires or protect them with the TitanRF Faraday Fabric Kit.

2.  Use High Pass Filters For All Your Speakers.

Set filters correctly to reduce excess bass that would otherwise cause distortion when it reached the door speakers.

However, many automobile speakers are not designed for powerful and deep bass. Because of this, pushing low frequencies on these speakers might cause harm.

Install a subwoofer if you want bass from your speakers, and isolate only frequencies over 80 Hz for the door speakers.

3. Decrease The Bass When The Volume Is High and Increase It When The Volume Is Low

Distortion will be audible if the bass goes beyond what the speaker can handle when playing loud music.

Therefore, you should set the head unit’s bass and treble to the appropriate levels. This lowers the likelihood of hearing cracking noises.

4.   Keep Loud Music Off.

If you don’t compete, too much bass will ruin the sound quality of your recording.

Even if your speakers are excellent, too much bass strains them at any volume level.

Additionally, playing high bass for an extended period harms your speakers in the long run.

So, refrain from playing bass-heavy music or sounds.

5. Inspect The Car’s Battery And Alternator.

If you have attempted to repair the wire connection, but the noise persists, there may be a problem with the automobile’s electrical system.

You will have to charge the vehicle’s battery in this circumstance.

Visit a professional to check the alternator and battery if the problem persists.

Additionally, there is a potential that the ignition is the source of the crackling noises if your automobile is old and hasn’t been started in a while.

How can you tell whether the ignition caused the crackles? Keep an ear out for a ticklish sound that changes speed with acceleration.

If the noise is excessive, the ignition system’s weak grounding may be to blame. Ticks are transmitted by inadequate grounding to other components such as the air conditioner, hood, and exhaust system.

Try grounding the underwood components to check if the sounds will go away.

6. Add A Noise Filter.

Whining or clicking noises will emanate from the speakers if the problem is related to engine noise.

Additionally, if the noise only occurs while the engine is running and the pitch of the noise varies with the engine’s RPM, your alternator is likely to be the source of the problem.

Average differences between this pitch and engine speed exist.

You may sometimes install a noise filter to get rid of this noise.

Additionally, you can mount the car amplifier on the dashboard using your feet or add rubber grommets to separate it from the vehicle’s structure.

If it doesn’t work, try utilizing several patch cable kinds.

If the noise persists, whether the engine is running or not, you should search for any other audio sources contributing to the issue.

Installing sound-deadening materials in the automobile might also aid in getting rid of this issue.


1. What Causes High Volume Distortion In My Speakers?

There are two basic causes of speaker distortion at high levels. The most frequent is that the audio source is distorted in and of itself. Speakers may also create distorted sound if their drivers are forced beyond the limits of their intended motion, reacting non-linearly.

2. How Is A Blown Speaker Repaired?

You must replace one or more components to repair blown speakers. A charred or melted voice coil in a blown-out speaker requires replacement and rewiring. Alternatively, a blown-out speaker can need the replacement of its cone and casing.

3. Where Is the Crackling In Your Speaker Come From?

A connectivity issue is nearly often to blame for speaker crackling. A faulty connection between your amplifier and speaker driver is causing the driver to move erratically and generating interference. The problem—the defective link—could be located in a variety of locations, some of which are simpler to fix than others.

First, one should examine the wires between the amplifier and the speaker’s terminals. Something may have come free if the wire has a propensity to move, possibly by a cat or dog. Check the connections even if there is no valid reason for them to have changed. Jumping forward will make you feel incredibly foolish once you find that the problem was simple to solve.

4. What If A Speaker Connection Problem Is Not Immediately Visible?

Examine the speaker’s internal connections. A solder likely needed to be repaired since it broke down after some use. It could be something you can address, depending on your skill set. Hopefully, fixing the problematic connection will be as easy as rejoining a loose wire once it has been identified.


Playing fantastic music in your automobile is one of the finest accomplishments to improve your driving experience.

However, individuals may make several straightforward errors that cause high- or low-frequency speaker distortion. Others may install elaborate and expensive sound systems, but they will still not obtain a clear output.

The issue could also be related to the design of the car’s systems or the vehicle itself.

Therefore, using the advice mentioned earlier should enable you to stop the cracking noise and lower its likelihood of returning.
