First off this sub sounds good but do not play rap with it. Thing bottoms out like crazy with the bass boost off and gain of my amp at 1/4. powered it with a Kicker ZX.300 so it defenantly couldnt handle 300rms due to the fact that it blew in one month and for that entire month all that could be smelled was voice coils burning. Dont waste the money and go with something else. I would recommend Kicker or rockford fosgate. Got so sick of the shallow mounts I just said forget it and threw two twelves with 2,000 watts in the back seat. Now thats what i call bass. These shallow mounts sounded like little 6x9s beside what I have now
