There is so much wrong with this. A Type R will get loud and sound nice in a small enclosure. And Ive heard some really nice sounding Kickers. It all depends on your set-up.kicker is for spl, but they are very expensive compared to subs that would be a lot louder and cleaner..alpine is a great subwoofer, but needs a decent size box as well too be loud, but better all around than the kicker...just my opinion
