perfect thanks, now for the input sensitivity, what am i looking for specifically so i can set it......or could i just keep adding bit by bit to get it to where it needs to be?

Just as extra info: i have a pioneer DEH-3800MP, it has different settings for low med and high bass.

and you said i should get a better precise amp, would a JBL GTO140001 be perfect? Its 1200w at 4ohms. but im not sure if its a bit over rated, now if it like 50w over does it matter when my subs are 600rms max?
