Rockford Fosgate T215D2 Car Subwoofer

This is a POUNDING subwoofer. People Think that sine it is 1000RMS they can find other subs that are cheaper that have the same power rating, but in my opinion RF under rates their stuff compared to other companys that say "3200W max" but its really only about 1800max and 900RMS or something. But the sound quality is unbeleiveable and this is one bad @$$ sub! I meen the subwoofer alone weighs 70lbs!
