THEY ARE FREAKIN AWESOME! I love them forreals! And they look tight at night when I drop my seats back oweeee. Sweet. Right now I'm running one p3000.1 at 2 channels. one channel per sub at 2ohms, so the subs are seeing about 1k or a little more. And right now they pound. I can't wait till I get my comps in and get some music going. Right now its just subs because I actually ran out of wire for the comps and comps are going to take awhile to hook up, but hopefully not. Anyways, these massive amps are good for the price no doubt.
box is 44inches lenght, 40inches width, and 20inches tall. tuned to 40hz. It was like 17cuft before sub and port displacement, and now its about 14cuft. And I gotta say, this box is nice! Can't wait to drive home this morning :D.
audioque hd3's and dd subwoofers love big boxes just to let you know! and their theory or style of boxes works. how do I know? because my subs bang, and they bang good.
