[QUOTE="fbi90909, post: 3742646, member: 568679"] right now it's rear battery grounded to the chassis with a 12" length cable. [IMG]http://i110.photobucket.com/albums/n104/fbi90909/100_0613.jpg[/IMG] battery sits directly above the ground. sub amp sits right above the battery and is grounded directly onto battery with a 10" cable. the 4 channel sits on the opposite side of the trunk which is being grounded onto the the trunk floor where it meets a frame like area that runs under neath the car. well, after dicking around some and moving the 4 channel onto the location of where the battery is to ground it to the battery the noise still existed, but only from the front speakers and not the rears. at this point i really don't think it's the grounding but it could be the amp itself. i will switch the outputs on the amps on having the 1-2 channel come out on 3-4, and vise versa, to see if the noise is being conducted in the speaker wire or if the actual amp is causing the noise. note: this is with the engine off and no RCA's plugged in. the amp itself is sitting on a thick towel so it does not come in contact with the trunk floor(no carpeting) [/QUOTE]
