[QUOTE="wew lad, post: 8429941, member: 665412"] I wouldn't ground to the battery unless you know your car has a body with terrible resistance, and even in that case I'd ground to the engine or frame then run a ground from your frame up front to the battery. If your car has no frame id ground it to the engine then upgrade your engine ground to battery. [I]Start a new thread so we can assist you better[/I], include what amps, headunit, etc you're including. keep it concise but provide as much info as possible and you'll get my help as well as a few others. the short story for what i think your problem is, is that there's a difference in ground impedence between your amps and the excess difference is being transferred through your RCAs when the second piece of equipment is plugged in [/QUOTE]
