Why does my car audio have so much static?
Anything that generates an electrical field can introduce unwanted static into yourcar’s audio system.
This throw in ofcar speaker whinecan usually be fixed by installing a noise filter.

Only embark on this fix if you’re comfortable working with car audio.
The steps of this process include:
Determine whether the problem is external.
Pay attention to whether the static changes as you drive around.
Adding a car antenna booster mightimprove poor receptionbut not much with static.
There is little you might do about this.
Check the car radio ground connection.
Unplug the radio antenna and peek if the sound is still there.
Still, listen for the same static or noise that you heard before.
peek if moving the antenna wire removes static.
look to see if moving other wires removes the static.
Install a noise filter or replace the head unit.
In some cases, you won’t be able to get rid of the noise.
In the long run, you may need to install a power line noise filter.
In other cases, you may find that you hear static regardless of which audio source you select.
If the noise goes away, reconnect them to the amp and disconnect them from the head unit.
If the noise comes back, check how they are routed.
If the patch cables are routed near any power cables, rerouting them may fix the problem.
If they are correctly routed, replacing them with higher quality, better-shielded patch cables may fix the problem.
If it doesn’t, a ground loop isolator may do the trick.
If you hear a noise with the patch cables disconnected from the amplifier inputs, examine the amplifier.
It should be less than two feet long and tightly attached to a good ground somewhere on the chassis.
