Versatility meets amazing bass when you combine Chevrolet’s cross-over vehicle with this intelligently integrated Stealthbox®.

This is a brand-new model that takes advantage of our amazing TW3 thinline 12-inch subwoofer drivers to maintain a much lower profile than our previous Stealthbox® for this vehicle.

Using the vehicle’s factory mid-gate attachment hardware, the Stealthbox® seamlessly replaces the mid-gate while maintaining its folding functionality. When folded, the Stealthbox® allows you to carry long items in the bed. To make sure your truck remains a useful truck, the 100% fiberglass Stealthbox® enclosure is coated with a durable material that is textured to match the bed.

The Hard Data: Contains dual 12TW3-D4 subwoofers in a sealed enclosure. 800 watt power handling. Wired for 4 ohm mono. Replaces factory mid-gate and maintains folding function to allow access between cabin and bed. Black texture coated finish. Black steel mesh woofer grilles are included. Rear glass storage is lost. Will not fit Hummer H2 SUT.
