So here's the deal. I've got a 500w RMS max sub w/ dual 4ohm VCs and a monoblock that puts out 600rms at 2ohms and 400rms at 4ohms. Right now I have the sub wired in series for 8ohms. I'm just wondering, how do you audio freaks suggest wiring the sub, for maximum bass, while not losing ALL of the bass quality????
