2002 Z28: When accelerating, I hear engine feedback in my stereo speakers. Any ideas? It goes higher in pitch as I go faster.

 

this is an engine tech forum...


maybe the boys in audio could help you out more

 

Could be a bad diode in the alternator, or more likely a ground loop problem in the stereo system.Frmula1 is right, put it in the audio section. Also give more details: Factory or aftermarket, amp(s)- number and type, etc...

 

check grounds, RCAs on stereos, and make sure your power wire isnt touching your RCA cable.
