I have finished mounting my processer, equalizer, amp, cap and distribution blocks on a piece of ply-wood on the back of my seat. Today I am installing my 4 channel amp under the passenger seat, it will be easy. (except for running the new wires through the doors)

A quick question my RCA splice cables between the EQ and crossover are behind the ply wood with the power wires. Will the 3 foot RCA's pick up a power signal? I noticed a little noise comming from my sub between tracks, but it might be that until I have the 4 channel amp in I had to run the gain pretty high. What do you think?
