This is probably the best JL product for the money. This sub is suprisingly loud and conservativly rated at 150 wrms. I have this sub in a 2.2 ft2 box behind the seat of my single cab truck and it is pretty loud. I have about 250 wrms going into it, which is more then reccomended but it doesnt distort at all. I can just imagine what it would be like in the rated box. Good spl and sq if you have a slim space to work with and on a tight budget. Looks pretty sweet too.
