Trust me, its your amp. If RCAs are disconnected, there is nothing else in the signal chain other than the amp, speaker wires, and speakers themselves.
There is always the slim chance your speaker wires are picking up noise, but I mean SLIM chance, unless they are the cheapest wire you could find.
Lets discuss how you set your gains.
My experience over the years has been to move ground first, then examine gain structure.
Southark370z mentioned using a filter on the power lead. I have tried several of them the past on other installs, and never had luck with them in an Amplified setup. They have worked for me on systems just off head unit power, though.
