1x1600watts RMS @ 1ohm
1x1100watts RMS @ 2ohms
depending on how much you are willing to spend on subs, you might not need both of those amps...
to be honest with you, if i were on a serious budget and had room, i would buy 2 05CVR Dual 2ohm kicker 15's, build the box myself (slot vented) to kickers compact ported enclosure specs, and wire them in series so i could send 1100watts RMS @ 2ohms to them...
but if i WASNT on a budget, (2) 15" ____________ would be sitting in the trunk...
