    usualy 2 subs on one 4 channel u would bridge 2 channels to each sub. your gonna hook 1 sub to ch1 (+) and ch 2 (-). other sub ch 3(+) and ch. 4 (-). what is amps power rating (rms)?(important, if amp puts out 1800w, which it doesn't, you might blow them subs . but would still like to know rms power per channel and bridged(4ohm)

    sounds like pretty serious 4 shannel. owners manual should say, but using wiring mentioned above they would c 900 each but since SVC, only 450 each, which sounds fine, just watch gains
