I have a 12 inch ROCKFORD FOSGATE POWER HX2, dual 2 ohm, 1000 watt @ 1 ohm and 2000 watt max. Very beefy sub. I got acouple of pics, Check em out. I think this hit harder then my FOSGATE T2 i use to own.
Its a pure SPL sub no SQ..Needs ALOT of power to bacc it up..Not made to be a daily driver..i use to have 2 of them and the box spec was 12.0 cubic feet just for 1 sub..I sold them cause i dont really need them so i got a Fosgat POWER HX2 instead..
