We are offering a new line of boxes that can fit those larger deeper 8 subs that wont fit in other boxes. We are talking about JL Audio 8W7s and Sundown SA 8s, Skar ZVX8s and More. We call these "Lift Kit" Boxes because they do require lifting the rear seat by 2.5 inches. But by lifting the seat 2.5" with a custom lift kit from LMI welding, this opens up the under seat area and allows the much needed space for those larger types of 8" subs. This box comes in a sealed quad 8 Front Fire configuration that will absolutely rock in your truck.
Besides being larger than ordinary boxes, our lift kit boxes are built like army tanks. They are built completely from 3/4 MDF and are glued and screwed together, Internally braced and come with a high end push style speaker terminals.
That's what it takes to contain these massive subs and Subthump knows how to deliver. The fit and finish of this box in your truck is excellent and the bass output is intense, making the extra investment is well worth it.
