[QUOTE="DarkFox, post: 3532472, member: 567531"] Thanks for some good info helotaxi, but what your saying is sort of what the dealer was getting at, thats why I am trying to get someone with alot of knowledge about the difference in inputs to post. I cleaned up a piece of the frame under the dash and ran a fresh ground from the radio to this point, as to bypass the noisy factory grounds. What your saying about the path being created inside the amp between front and rear channels and causing a feedback loop, is exactly what the dealer was talking about, and per what I gathered with our conversation and my understanding of it, the differential inputs almost acts like 2 separate amps inside the one, and does not allow the amp to create any circuit between the two pairs of RCAs. Thats why he was saying something like a JL, that has the differential inputs, would allow me to plug all the channels into the same amp, with out having a feedback loop, or any bleed through created inside the amp. He also said with amps that have non-differential inputs radios like kenwoods work good cause of diffrent grounding. Just to add to what else I have done to prevent this: RCAs run opposite side of vehicle All cables run away from drive train High quality shielded RCAs Radio grounded to frame in dash I pretty much did everything I could to keep noise out, and I am not inexperienced in car stereo, AND I added isolators after all appropriate measures were taken, I still get noise. Thats why I think it may be something with the equipment not liking each other. But everything you guys had to say was good advice for a place to start, but I am posting this thread cause I have done it all already. [/QUOTE]
