[QUOTE="lpm, post: 8728896, member: 645421"] Hi - I am chasing an alternator whine on my newly installed system. If I unplug my RCAs, the whine goes away, but touching the outer RCA directly to a jumper cable on the negative battery post brings back the whine with RPM. I have replicated the issue with 3 sets of shielded RCAs and my amp is also grounded directly to the negative battery post as well. Should directly grounding an RCA cause whine, or is there a problem with my amp? Thanks! [/QUOTE]
