2002 Z06 factory stereo. While driving down the highway my stereo lost almost all of it's power and the sound became muffled and scratchy front and rear.
I bought and replaced the head unit with another factory unit from a forum member and it fixed the problem with the exception of the rear speakers. The rear speaker now screech and have a ton of static. It's sounds like a record that is badly scratched. Front speakers are fine with no problems.
Any ideas what is going on??

Did you check the ground for the radio? Does the same problem exist with CD and radio?
