Im not new to the world of car audio but far from a pro. Ive researched subs and amps and the like but need other peoples opinions, mainly people who know what they are talking about. Anyway, i was wonder what is the BEST subwoofer availble for SPL period. Ive got a 10 channel Bose home theater so its time for bass! Strickley MASSIVE SPL. Please give me your opinions regardless of how much the sub may cost.
