The subs are wired to the factory amp so you don't need to do anything there.
oops my bad... of course its only 2 channels... we only run left and right out of the head unit... I believe the amp has a built-in crossover for the subs so it looks like it has 4 channels or rather 4 outputs.
damn it... still can't post the schematic... oh well I will eventually...
