## Description

Our 01-06 GM HD Crew cab downfire box is designed to fit both the the bench seat rear and the 60/40 split rear seat. You've probably noticed that there aren't a lot of boxes out there for this particular truck. Many of the boxes out there are quite generic-looking or don't fit too good. Not to mention that when their ad says you must remove this bracket or that bracket, they actually mean that you have to "cut" the bracket out of the truck. Not with our box. Our box, on the other hand, requires no modifications to the truck whatsoever. The box fits great and sounds even better. It molds around every part of the under seat area, including all the tricky seat bracing and supports for an authentic-custom look. You don't even have to take out the jack. One of our customers suggested that you can drill another hole in the bass plate of the jack so it can simply be rotated out of the way and re-positioned. Other than that, just drop the box into place and start. thumpin'. This box is a must-have if you like your bass low and loud in your HD crew cab. With out a doubt, this is the loudest best sounding style box you can put in your crew cab, making this box our best selling box for this truck. Don't settle for anything less than a quality crew cab box from Subthump. If some other imitation looks 'cheap', it probably is just that. Our box is the real deal. Note: Will Not fit the Light Duty 1500 series crew. Fits 2500 & 3500HD crew cab only. Please note that due to speaker variability across the industry, Subthump takes no responsibility for subwoofers that do not fit this cabinet.
