DB Audio sub 500 watt sub woofer NO BOX. !

DB Audio 500 watt sub woofer NO BOX. Sounds really nice but will sound even better in a box, nice and bassie very similar to the 10" pioneer. Has push spring terminals which makes a much better connection and you wont have any snapped screw terminals like other subs can get when over tightened. 30 O.V.N O
