My freind is hooking me up with a prety sweet deal, a Kenwood KAC-X811D 1600 monoblock class d amplifier, 1600 watts max 1000 rms *2 Ohms 516 *14. He wantd 250 for the amp brand new, seems sweet enough but wat i want to know is will this amp power my subs well ( Audiobahn 450 watt rms 800 peak, wired at 4 ohms each)
