View Full Version : Weird sound on new stero when accelerating

03-12-2008, 04:06 AM
I have just installed a new radio in my car, I took out the factory one and put a new one in. Pretty sweet unit, sounds better than my old one. Once I got all done I was driving and when I am accelerating, I can hear this noise that does not belong... It high pitch like. Its very low, and only happens when I am accelerating... Any clue why its doing this?

its called alt whine, make sure that your grounds are secured and making a good connection and that should fix your problem. also is it a pioneer cd player?

Alternator whine...Fix your grounds and it will go away magically.(Well most of the time.)

as he also said with that head unit you dont need to have a amp on it , if it has a crapy ground you wont ever see if fixed untell the headunit is replaced(you can replace the grounnd yourself in the wire harness if you want to but 9 out of 10 its a prob inside the head unit)
