I get some kind of ground noise from my speakers when i turn the gain on my amp anywhere past the minimum which does no good since I cant hear anything there. I currently have my amp grounded on a bolt next to the clip that holds down the rear seat, what is a better grounding point for my car as I have heard that the noise is related to having a bad ground. *also, I have my power,ground, remote turn-on and left side speaker wires running on one side and the rcas and right side speaker wires on the other side, is this setup correct?
