Well 4 reason! 1 This box is sicko, it has a black light and a mirror. This will look so sweet with the W3's since they have JL in white on them! 2 pluss then my subs are protected from all kinds of stuff hitting them. 3 It will hit alot harder! 4 its alot lighter... I also would like to go fast! The current box is heavier than sh1t!
