What Causes Car Speakers Crackling, and How to Fix it.

Where could this crackling sound be coming from?

Most of the time, a speaker’s crackling sound is caused by a problem with its connections.

Here are the two main reasons why speakers don’t connect well:

  • Worn out speaker wires

Most old car audio systems have this problem because the cables have been damaged. For the best sound, I’d recommend 14AWG speaker wire, which you can get on Amazon. It’s also worth upgrading factory speakers to high-quality OFC wires.

  • Damaged connectors

Most broken connectors are at the speakers, because when the speaker wires move, the connectors get loose. For example, this is more likely to happen with speakers in the back decks.

On the radio side, the harness is usually in good shape, unless it is packed tightly in the dashboard.

If you have these issues, try replacing the broken connectors with strong FIXITOK spade connectors.

When the wires and connections have been checked and found to be fine, the crackling sound could also be caused by a broken voice coil.

Inside the magnet is where the voice coil is made.

There is a small space between the voice coil and the magnet. If the voice coil moves out of place, it could touch the magnet and make a crackling sound.

When this contact happens, it makes a short cut. Even if shortcuts don’t last long, this is a good reason for the speaker to crackle.

What would cause a voice coil to go out of position?

  • The speaker could have been made with the problem.
  • The cone or suspension of the speaker was fixed and put back together, but the voice coil was put against the magnet in the wrong place.
  • If you changed the voice coil but put the new one in the wrong way.

The crackling sound can also come from a speaker that is connected to a broken amplifier or pre-outs.

If the amplifier is broken, the speakers usually won’t work, but this isn’t always the case.

Also, if the problem is with the pre-outs, you will need to fix the amplifier or buy a new one, depending on how bad the damage is. If the amplifier is broken and you need to buy a new one, I would recommend the BOSS Audio Systems R1100M Monoblock Car Amplifier. It is powerful and has good sound quality.

How can a sound that cracks hurt the car speakers?

If the speaker makes a crackling sound, it might already be broken. If you don’t, a broken current could cause the voice coil to be overworked, which could damage a mechanical or electrical part of the speaker.

  • Broken or cracked cones and voice coils that move erratically because they have been overstretched cause mechanical failures.
  • The electrical damage, on the other hand, is caused by the voice coil being broken or blown.

So, if your speakers make a crackling sound, try not to use them until you figure out what’s wrong. If you don’t, you could damage the speaker and other parts of the car stereo.

How do you fix car speakers that pop and crackle?

After you figure out what caused the problem, you need to find a way to fix it.

Steps:

  • Fix the connection between the amplifier or radio and the speakers

If your car speakers are making a crackling sound, the first thing to do is fix the wire connections between the amplifier and the speaker.

A child or pet may have moved the wire around a lot in the past.

To test this, turn off the system and unplug the speaker wires from the amplifiers.

Now, give it a try to start.

If the noise is still there, it could be that it is getting into the wires.

So, move the wires or protect them with the TitanRF Faraday Fabric Kit.

  • Use high pass filters for all your speakers

Set filters in the right way so that too much bass doesn’t hit the door speakers and cause distortion.

But many car speakers are not made for bass that is strong and deep. So, forcing low frequencies through these speakers can cause them to strain and break.

If you want bass from your speakers, you can install a subwoofer and set the door speakers to only play frequencies above 80Hz.

  • Decrease the bass when the volume is high and increase it when the volume is low

If the bass is too strong for the speaker, you will hear distortion when you play loud music.

So, you should set the head unit’s bass and treble to how they should be. This makes it less likely that you’ll hear crackling sounds.

  • Avoid bass boosted music

If you’re not in a competition, too much bass will ruin the sound quality of your music.

No matter how good your speakers are, extra bass puts a strain on them at any volume level.

Also, if you play very high bass for a long time, it will damage your speakers in a way that can’t be fixed.

So, don’t play or listen to music or audio that has too much bass.

  • Check the alternator and car battery

If you’ve tried to fix the wire connection and the noise is still there, the problem could be with the car’s electrical system.

In this case, you will need to charge the car’s battery.

If the noise still happens, have a mechanic check the battery and the alternator.

Also, if your car is old and hasn’t been turned on in a while, the sounds could be coming from the ignition.

How can you tell if the crackles are coming from the ignition or something else? Listen for a tickling sound that changes speed as the car speeds up.

To fix this, you will need to tune it with JDMSPEED New 10.5mm Spark Plug Wire Set resistor-type spark plugs coil and distributor cap.

If the noise is too loud, it could be because the car’s ignition system is not well grounded. When there isn’t enough grounding, ticks can spread to other parts of the car, like the air conditioner, hood, and exhaust system.

So, try grounding the parts under the wood to see if that stops the noises.

  • Install a noise filter

If the problem is related to the sound of the engine, you will hear whining or clicking from the speakers.

Also, if you hear the noise when the engine is running and the pitch of the noise changes with the engine’s RPM, it’s likely that your alternator is broken.

Most of the time, this pitch is not the same as the speed of the engine.

So, putting in a noise filter can sometimes stop this kind of noise.

You can also put the car amplifier on the dashboard or use feet or rubber grommets to keep it from touching the car’s chassis.

If that doesn’t work, try different kinds of patch cables.

If the noise stays the same whether the engine is on or off, you need to look for other noise sources that are making it.

Putting things in the car that block out noise can also help get rid of this noise.

Conclusion

One of the best things you can do to change the way you drive is to get good music for your car.

But people can make some simple mistakes that can cause speakers to distort at high or low frequencies. Others may put together expensive and complicated sound systems, but they won’t be able to hear anything clear.

The problem could also come from the car itself or from how the car system is set up.

So, the above tips should help you fix the noise and make it less likely to happen again.
