[QUOTE="maylar, post: 86941, member: 541144"] I had an alternator whine that defies explanation. I had two pair of 17' RCA cables comming from the rear HU channels. One set went through a dash-mounted volume control for my subs, the other was for the rear speakers. Front / rear channels were a USX 4065, the subs were on a RF 2 ch amp. The alternator whine came out the ~front~ speakers, really nasty. I rewired the system to use the USX amp for the subs (still with volume control) and the fronts off the RF. Noise went away. No change in grounds. Only thing I can figure is that 2 long cables are too much load on the HU preouts, and somehow made it susceptable to alt noise. Really dunno.
