Your cart is empty.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.

Threw this box in today with a pair of kicker compR10s box fits in the truck flawlessly. Sounds pretty good but doesn’t hit the lows as good as I was hoping maybe needs more airspace could be my sub combo idk I’m not an engineer😂 But you can’t really get anything bigger in there so it is what it is. Love it, highly recommend.

Box that I received sounds like crap. Leaks air through the seams and sound very bad. Bass response is very poor unless you're a techno listener. Does not reproduce the lows you want in most music and if you like rap, forget about it. Horrible.... biggest flaw is that they put a divider between the 2 subs making them individual boxes. This would be fine if running a 2 channel and running left and right bass tones. With most amps these days and how people run mono amps the signal is combined so the box should be an open design so the subs work together plus it would add more air space with is very much needed. This box would be great for an 8" sub but .55cuft for a 10 is way too small. There are other options and cheaper that work better. I bought this one base on the reviews. Well Here's mine.... I hated this box. But for all those who ask YES IT WILL FIT A 2002 1500HD crew cab.

Tight fit but Sub Thump sure made it work! Only downside to this box but I expected was that you will not be able to get the back of the seat all the way down like in my last picture. Loaded up with a pair of T1S2-10s ran at 1ohm. Material seems solid but I will update if I run across wood separating
