Our new Large single downfire with amp space fits just like our other boxes for this truck.  What we did is integrate our amp box and dual box into one.  So we have one large chamber for sub volume, along with an amp shelf.  Everything else stays the same as our other boxes.  We still have 1.75" of clearance underneath and the overall width the the same as our dual box.  We trimmed out the amp shelf so that once the seats are folded down, the amp is not visible.  But the openness at the rear leaves airflow for cooling.  We also installed a convenient speaker terminal connection right next to the amp shelf.  If that isn't enough already, we also offer the Silverado logo as an opton.  All these things make Subthump your trusted choice for your new crew cab sub box.

Purchased this box for my 2018 GMC sierra crew cab. First off, the box is very well made. I have had audio installs in every vehicle I have ever owned, so I know quality when I see it. The cuts are precise and clean, all inside seams are sealed very well with silicone, and the carpet job is very nice. Fitment of the box in the truck is spot on. The amp rack space is perfect for my hertz hdp4 amp and audio control lc2i with room to spare. Should be enough room for 2 digital class amps easily. The sub I used is a memphis PR12 with about 5.25" mount depth and a 6" magnet, which fit just fine in the box. Highly recommended!..
