i figured it out...i cut back that black stuff holding the mass of wires togeather, which btw makes a sticy mess...anyway there are sets of 2 wires twisted in ther so i figured that those must be the ones going to diffrent channels...choose a set i thought to be for lower speakers, spliced in and it works...but i was bad and i used the 12v that was back there, and unplugged the stock sub so i should be ok as far as overloading goes...it makes such an improvement...i can crank the bass on the head unit to 0 and still have great bass...if youre in detroit i would say check out car toons!(place where i purchased mine)
