Hi everybody, I know that i have alternator whining because when i turn on the engine, my speakers start to whine and when i rev my engine or use any of the electronics in my car, the speakers will make noises or get louder. I'm pretty sure i've narrowed it down to the RCA's grounding out somewhere, but i have no idea whether it's on the 4 channel 800W amp im using or if its the Alpine CDA-9856 HU im using. I've seen simple fixes like grounding each RCA cable on the HU but that doesn't seem to work for me. Does that mean it would be a problem with the amp? Either way does anyone know a fix that wont weaken my speaker quality?
