Are those dual voice coil subs? I'm fairly certain that all Kicker squares are DVC so assuming they are, yes a final impedance of 2ohms is attainable and should be very loud with that amp. I installed 1 L5 12" in my girls Cherokee and it's loud. Very loud for one sub.
Heres what you need to do for a 2ohm final load:
Wire the subs with the voice coils in SERIES. This will give you 4ohm impedance for each speaker. Then, run the subs together in parallel and there is your 2ohm final impedance.
