Are you wondering how to fix car speakers crackling? Well, you have come to the right place, because we understand how annoying this issue can be when you’re just trying to listen to your favorite tunes. This is a pretty common issue, which is not only exactly why I wrote this article, but it means that you can have this fixed in no-time.

What is causing the issue?

The crackling, popping or static noise of a speaker is almost always caused by a simple connectivity issue.

What this means is that somewhere between your amplifier and speaker drive there is a bad wire. This bad wire then causes the driver to move more abruptly, thus causing that interference with your music. Whilst this seems easy to combat on paper, it might not be.

Due to you not knowing where this faulty wire is, a challenge posed when attempting to find out where it is. Another issue that could be causing this crackling noise is a possible ground loop from your mobile device, as explained quite well in the following video.

What this means is that an individual will take their mobile phone and connect it with a 3.5mm AUX cable to the cars AUX input, After playing music for a while everything will seem fine, but when you go to plug it into the cigarette lighter (obviously doubling up as a charger) some crackling and popping noises start to occur. As mentioned, you have created a ground loop which is when two points of an electrical circuit have different potential between them. So, the first step is to identify which of the two problems is causing the crackling sound in your vehicle, and once you have done that you can head on over to the next paragraph to see how to fix this issue.

How to fix the crackling noise

So, if you have done some research and identified the issue to be the first one mentioned, the first step is to check the wire connections between the amplifier and the actual terminals on the speaker.

If the wire has possibly been moved around a lot in the past, by maybe a small child or pet, it is likely that something has come loose. Due to this, even if there isn’t a real reason for the connections to change, you should check on them anyway.

If you have checked and everything seems to be in order, a solder may have broken down and may now be in need of repair. If this is the case, depending on your skillset, you should probably call a professional in to have a look at it as it is a pretty complex job from there onwards.

If you identified the crackling to have been caused by the second issue, the simplest way to solve this is to purchase a ground loop isolator.

The ground loop isolator simply adds into the single path, is really easy to use and is relatively cheap. It will work to break the DC circuit path for the audio shield ground circuit, with then allows for the connection to flow and your cigarette charger to not interfere with the AUX cord.

This will then guarantee that your music will not be a static or crackling noise as a result of its previously mentioned abilities, and if you did incorrectly identify the cause of the crackling noise and the ground loop isolator has no effect, you can easily return it and claim your money back.

Conclusion

Remember to follow the previously mentioned vital steps if you wish to get rid of that annoying crackling noise and back to your music, those steps being:

  • Correctly identify the cause of the crackling noise
  • Follow the steps on how to combat the crackling noise
  • If need be, purchase a ground loop isolator at the following link
  • Get back to enjoying your high clarity music
