I had my car audio system output distorted sound, and it turned out it was just a loose connection between the amplifier and subwoofer. However, this is not always the case, and sometimes the problem may not be resolved so easily.

However, you are advised to always go through these steps before anything else. Now we will move towards other possible fixes:

Replace The Subwoofer

Try testing a different subwoofer; if that fixes the problem, it indicates a faulty subwoofer. So, replace it with a quality subwoofer to fix it.

Check The Cables

Look for any damage in the cable connector, such as corrosion or torn-out cables. If there are any such cables, you need to replace them immediately.

Adjust Bass As Per Volume

You need to increase the bass when you are playing music on a low volume and decrease it when you’re playing it on a higher volume to get a richer experience from your speaker driver. Keeping both the bass and the volume high is known to cause audio crackling issues.

Make Use Of High Pass Filters

Filters properly configured will prevent excessive bass from reaching the door speakers, which might cause distortion. Most vehicle audio setups are not designed for deep and strong bass; introducing low-frequency signals into them can damage and eventually destroy them.

The Speaker’s Voice Coil is Incorrectly Positioned    

The magnet contains the voice coil. A small gap occurs between the voice coil and a magnet, and when the voice coil is oriented off-centre, a crackling noise is produced.

This contact creates a current shortcut. Although shortcuts last only a fraction of a second, they cause the audio system to crackle and generate noise.

To resolve the issue, disassemble and accurately position the voice coil.

Avoid Playing Bass-Boosted Loud Music

Excessive bass is bad for sound quality and must be avoided unless you’re contesting. Too much bass stresses the sound system at any sound level, regardless of how good it is. Bass-heavy music creates irreparable speaker damage if played over a lengthy period.

Use a Ground Loop Isolator

A ground loop might be to blame for a whining noise from your car’s sound system. It’s tough to determine for certain without inspecting your exact automobile audio setup; however, your audio system might suffer from a common ground loop issue.

Ground loops arise when two components are grounded at distinct ground potential locations. This can result in an undesired current, which causes interference, which is sometimes described as a hum or a whine.

Does Crackling Sound Mean my Car Speakers are Damaged?

Cracking can harm automobile sound systems, although this depends on several circumstances, including the loudness of the crackling and the type of speaker.

Speakers are built up of numerous little components, and if any of them is broken, the entire sound quality of the speaker will suffer.

A little crackling may not be harmful in some instances, but if the crackling becomes excessively loud, it may damage or even destroy the sound system.

For example, when my car speakers were crackling, they were crackling loudly, and I tried everything to fix them, but nothing helped. In the end, I had to replace them.

In summary, if the cracking is loud enough, it might harm the automobile sound system. So it is advised that you fix the speakers even if you hear a little crackling, or it will not be good in the long run.
