No Amp + Aftermarket Speakers=Crap

That was a clear explanation, thanks. I'm going to take a good look at it tomorrow, sand the ground down again and get it the best I can, I'll let you know the result.

After talking to a few guys at some audio shops, I ended up just paying 15 bucks and getting a ground loop isolator. Went out and plugged it in and BAM the noise is gone. Messed around with the gain a little and everything's just about perfect. The alternator whine can be heard slightly, but really only if the music is almost off or not on at all. Thanks for the help everyone.
