Yep that was it I took and old set of RCAs and stripped the wire back for the out shield and grounded on another set of the RCA outputs(I have three) and it worked like a charm. Thanks for all the help guys!

alaskanzx5 if you messed with the rca's at all without disconnecting the power to the hu then i would put money on the hu being the issue.

drifterboyE3 It's a deh3900mp I believe. And yes I had that problem before wires touched and blew the ground. So I got a new deck(same one) and that solved the problem. It's just now that I put them in the focus. They were in an escort

sleepyboy I dunno, I actually grounded mine in the same spot as y'all now that I think about it. You may want to check all your grounds underneath the hood and make sure the battery and the motor are properly grounded and getting a good connection. Also depending on what car you have some have little resistors or noise isolators that are supposed to the do the same thing. I've replaced mine on my focus before though the noise it let through was very small and almost unnoticeable.
