I fixed it!! I went to Shitty-O Rack (Radio Shack) and bought 2 of those noise suppressors. I put those on my RCA's and made sure to move them farther away from my power cables. I was amazed that it worked. No alternator whine and, more importantly, NO POWER THUMP. And Circuit Shitty said it wouldn't work. Jeez
