We Told Ya They Were Worth Waiting For!!

Our boxes for the New GM Crew Cabs are simply Awesome and our customers have told us so repeatedly.  We've seen a few other boxes on the market, but nothing compares to these.  Instead of rushing a piece of cheap ugly junk onto the marketplace, we took our time and perfected one heck of a box and we know you will love it (which ever one you decide on).  You can stop searching all over the net because you've just found what you've been looking for.  Yes, we are the manufacturer of this box, not some re-seller who knows nothing about the product.

 So if you're looking for a true custom box that real subs actually fit into, then you've come to the right place.  Because with our box, you are not limited to slim woofers because everybody knows the slim woofers just don't pound like normal woofers do.  Check out the photos below and to the left and you will see the kinds of woofers that will fit into this box.  If that's not enough, the styling of this box is just unbeatable how it blends under the seat.

You don't have to go back too far to know that Subthump makes great boxes for GM trucks.  These boxes may be the new kids on the block, but we have a  feeling that they'll be making a name for themselves pretty soon. 

News Flash: Subthump's NBS Silverado Sub Box Goes Hollywood!
If you happen to make it to SEMA last year, our NBS Chevy Crew Cab box was featured at the 'Truckin' Magazine" Booth.  
Our dual box with Silverado Logo (CRB07-210) was on display in that truck as well as showcased in that month's magazine.  Be sure to pick one up.  You can see the highlights here

Dual 10 or Dual 12 Downfire Box 







Our dual 10/12 box is great-looking and fits incredible.  Plus, we can fit much larger subs than anything out there so far--or at least until our design is copied--which we've caught a few places doing in the past. (yes, we know who you are).

Our box fits 10's, 12s, even 10L7s. And with more sub to floor clearance than anything out there.  1.75" of clearance is standard on these boxes.  Enough for some of the hardest hitting 12s you can fit in there.  This box is the heavy hitter so if you like lots of bass from two 12s, then this is the one for you.  

And if that isn't enough already, we also have the New Style Silverado Logo as an option for most carpet colors.  All these things is what makes Subthump your trusted choice for your new crew cab box.

Dual 10 or Dual 12 With Amp Space Box 






If you've been wonderin' where in the heck you can mount an amp in this truck and still have room for a pair of subs, then you're not alone. At Subthump, we are always thinking about the end user and how they will use our product.  We try to come up with ways to make installs go much easier.  Most places don't care.  They just want to keep cranking out their one generic design without regard to the person installing it.

Our amp space box makes installing your amp and subs simple, fast, and easy.  Almost downright enjoyable.  Just mount your amp on the shelf, run you're wires and call it a day.  The amp space is 14" wide by 17" long.  Longer amps can actually run off the box in the back if needed.  You can also drill thru the shelf to help hide some of the wires as shown to the left.  

This amp space box can fit two 10s OR two 12s.  Please note that the amp area takes a little away from the enclosure's total volume, so if you're using 12s, then we recommend the subs to be suited for that amount of air space.  There are a few out there that will work, but for the most part, we recommend sticking with 10s.  

Not only does this box look and fit great, but it adds a whole new dimension of functionality and usability.  We can already tell that this box is gonna be a hot commodity for these crew cab trucks.

Single 10 or Single 12 Downfire Box 




If you're looking to add some decent bass to your truck without going overboard or don't want the extra cost of a big box and another woofer, then our single box is just what you need.  A sealed downfire box that fits on the driver's side and will save almost half the space under the back seat.
