Both are good subs, but with your power, I would suggest the LVL 4 12", they will be quite impressive off 1200w each. I had a LVL 4 18" off a Kicker 1200.1 and it was quite loud and low.
The AQ are nice subs, but honestly they will want more power than that. Is not that they need it, its just the DCs would make better use of that power range.
