yea i'm using a pioneer deh-p930. The older one with the 6.5v pre outs.. The reason i'm using the 4-channel amp is because the mosfet chip is burned up in the HU and because this HU has the 6.5v pre outs.

start at the back of the head unit. make sure you have a secure ground for it. keep your RCAs from power wires (I can move my RCAs 6 sinces and hear an increase in noise... so the people who say that its not the RCAs by power wires are wrong.) make sure your amp has a secure ground. are you, by chance, using a pioneer hu?

What kind of RCA's are you using? I've had my RCA's touching 1/0 and never had that problem.

All of my grounds are now connected at the same point and the noise is actually worse!! I thought for sure it would clear it up a little bit.. I've also tried moving my RCA's away from the power.. And i've tried an inline filter.. Still nothing.. WHAT DO I DO!?
