Car stereo <span title="noise..........................?">noise.......................</span>

Question

I never had a problem with my car's factory stereo system, but I installed an aftermarket one yesterday and there is noise--high-pitched sound that increases as the engine RPM increases! This new radio comes with an in-line filter; a little box with components and fuses attached to the power cables which is supposed to filter out noise, but apparently it's not doing it's job. How can I get rid of this noise? Do all after-market stereos do this? My car is a Toyota Camry.

Answer 1

you need to install a noise filter

Answer 2

I have the same problem. I think it&#039;s because of the way the wires are run..

Answer 3

You have what&#039;s called alternator whine. Try grounding the cd player in a different location other than on the factory harness. This wire usually makes a very poor ground due to it&#039;s length, small wire gauge, close proximity to other power wires, and unknown termination point. Instead, ground the source unit directly to the chassis or firewall.

Answer 4

this might sound stupid but it works.

try cutting the head unit ground wire totally. the antena wire would be the ground of your HU.
