So I've tried connecting the amp directly to the battery. Same thing. Alternator noise and a low static sound. And then I tried a different amp. Same thing. I definitely think it's the RCAs now. They aren't, however, shitty RCAs. But I do think they are the problem.

What kind of replacement RCAs should I get? I don't know what good brands are for RCAs. I need them to be about 17 feet long and 4 channel. I think the Stinger 8000 series look promising.
