right now i've got a hdc318 running off of a hifonics brutus 2000wt....in 5.9cubes at 37hz, and it's really loud, but it just looks like the sub is begging for more power...btw i only set the amp (with dmm) for 1700wrms, i figured that was bout all i could get out of it anyways.....but would it be worth selling the brutus for the AQ2200, i would have the big 3 done with 1/0ga, and 2 dump truck batts....(those batteries are a size 31, and put out 1000cca's, so i figure they do pretty good)
