Thank Matt.

I have my power cable running through the center cousel (along the transmision hump) and my RCA's along the passanger side. I'm wondering if my RCA's are picking up some noise from a component under the glove box or something.

I've grounded my amp and sub to a bolt under the rear seat. I've eliminated the amps as the source of noise by doing a few troubleshooting techniques. It is either coming from the RCAs or the empeg itself...
