I have Some old amps that I bridged one is a kenwood that pushes 800W @14.5v 4ohms, the other is a Denon pro. that pushes 500w @14.5v 4ohms they are both 2 channel. I want to hook up all 4 channels to two 12" kenwoods for max power/watts how can i do this? If i can't I also have 2 Alpine 6x9 (250w)3way and 2 pioneer 6 1/2 (150-200w)4way how should I hook them up? Right now I have the Highs runnin off the head that is (50Wx4channel) and i have my subs runnin off of the bridged Denon but there is still two channels loose from the kenwood. What would you do? and What could I do? P.S. i want this to hit hard!!! and loud as possible
