Late to the party here, as the others stated check your ground. I know audio control recommends that you ground their unit to the same ground as your amp, on top of that they also recommend running the ground of the amp directly to the battery which I have never had to do. Unplug the RCA's from the amp and see if the noise is still there, this will help track down what is causing the problem. And as stated X2 on the LCi2
