Stupid Question
 

If I were to wire my sub from the rear speaker wire, to the high level inputs on the amp, would sub volume adjust with stereo volume? Or does it adjust no matter wether I hook up through RCA or high level input?

Well the input, being that its the same as the rear speakers, will vary with the volume, thus the output (sub volume) will as well. The RCAs will do the same but with better control and quality. I have have bad experiences with high level inputs. Clipping that I couldnt tune out, it was awful. Just run RCAs

Ok just wanted clarification before I pulled trim to run wires. Thanks.
