I got a BL 15 fully loaded, daily, and got it in my car. Its in a 3 cuft @ 37hz box with 54sq. in. port. I think something may be wrong with the sub because almost all high notes not only sound horrible, but they arent that loud either. The low notes are loud enough to shake the wipers and steering wheel..around 143 - 145db legal. The sub is a little louder on lows than my old sx 15, but the sx kills it on sq and can actually play everything. Had a rockford t2 in this box awhile back and with the same power is was far beyond my sx...so idk whats wrong with the BL. This sub is definantly not what i was looking for.... Anyone else got a BL or know anything about this??
