first off. most people believe the birth sheets are bs.i would personally take the kx1200 over the bxi1606d. im not saying the hifonics amp is weak but as stated earlier, Kicker has a much better build quality. Also take note that Kicker amps are underrated. I've seen birth sheets by Kicker that produce 100-200 more watts than what the amp is rated.
correct. at least. it "shouldn't". I dont know if it really can or not.what impedence? Kicker wont go down to 1 ohm IIRC.
