[QUOTE="Zula, post: 8443583, member: 667834"] So recently setup a new system in my car, 2 amp's one 4 channel running 4 speakers and one running my sub. Before I just had head unit running speakers and it worked fine without any alternator whine. Now in the speakers I'm getting really bad alternator whine, I've tried everything regrounding, ground loop isolators, shielded RCA cables, along with grounding them just to be safe, and even trying another head unit. My amp is good the whine goes away after I unhook RCA's from head unit. I've had the alternator tested and it's good. Both amp's are grounded seperately. I'm at my limit I can't figure it out. Not sure if it matters, but if I leave RCA's unhooked but hookup the ground loop isolator, it has alternator whine again as long as it is connected to ground, it gets it. Doesn't matter if its the ground coming through head unit or from loop isolator [/QUOTE]
