You'd better be serious about bass, cause we've now moved into sizes that separate the lovers of great bass performance from the truly psychotic. Install a couple of DXi124 SVC's, and right after you get your hearing examined, get your head examined. At least that's what anyone who doesn't understand a true bassophile's desire will think. With a heart pounding 360 Watt continuous/720 watt peak power handling capacity, the DXi124 SVC does more than sound great. It will make permits to carry these things mandatory.
