Alternator whining

ok here's my problem, I have an alternator whinging in my car. Somedays it's louder than others. Sometimes when I juss tap the gas it goes away for a second. I have my power wire ran on the driver side back to my 2nd battery. thna I have my RCA's and my speaker wires on my passanger side. in my trunk I have a power wire that juss crosses my rca's but even before they used to be crossed it still whined. I've also change all of my grounds, on my battery, amps, and CD player. What else could I do to stop whining.

are you sure your grounds are good? try grounding everything to the same location. try grounding your deck to the battery. try different rca's, borrow an amp to test, and a deck.

Ground the RCA's. That solved my noise problem. Yeah, it sounds weird, but its worth a shot. Just pull out your head unit, take a piece of remote wire, and attach it to all the RCA's, and connect the other end to the chassis of the deck.

well when i was fiddling around in my box of car stuff I found that I had some 4 awg wire, so I upgraded some enging grounds. I did my battery and egnine grounds and it took 95% of it out. now u can only hear a lil bit of it when my stereo is turned off. It's ok for tonight, but I want this eliminated.
