What subwoofer should I choose and why?

personally i think they are all junk. I have 7 ISACA awards. 5 are from db drag. Ive hit 159.9 db with two 10" Planet Audios in a center fire vented box and that still hasn't been beat. buy where the worked records are comin from. fosgate USE TO be amazing, not its just the OEM CRAP that comes stock in a friggin mazda
