[QUOTE="stereo jock, post: 5029923, member: 602068"] It sounds like you have a bad ground. Usually they are hard to find, but I would guess that they used the factory ground behind your head unit. That's a good enough ground for an oem and most cd player only type headunits. When you add anything else like satellite radio or an amp, you really should get a better ground then that. Check out this article it may help you. I would just go back to the shop and say, "my stereo has a bad ground, so now I have a ground loop that's giving me noise and feedback". I guarantee they check it out and then change the ground; if to do nothing else but to rule that out. Read the one about Engine Noise.
