The Ground Shaker GS-DTOYXL28B is built for truck owners who want real bass without giving up space in the cabin. Designed as an under-rear-seat dual enclosure, it keeps everything tucked away and clean while still delivering deep, controlled low-end output. The upward-firing design helps push bass into the cabin so you feel every note without rattles or muddy sound.
Made from durable 5/8" high-quality MDF wood, this enclosure is designed to handle heavy bass while staying tight and solid over time. It features 1.32 ft³ total air volume with two separate chambers (0.66 ft³ per sub), giving each woofer the right space for balanced performance. Airtight sealing with Titebond silicone and premium wood glue helps lock in clean, accurate bass response even at higher volume levels.


Wrapped in a rugged trunk liner carpet finish, the GS-DTOYXL28B blends nicely with your truck interior while staying protected from daily wear. Dual binding post terminals make wiring simple and secure, and the compact under-seat design keeps your cabin functional and clutter-free. Just note, this enclosure is not compatible with Crew-Max models—but for Double Cab setups, it’s a clean, hard-hitting bass solution that performs way bigger than it looks.

Experience big bass from a slim, all-weather design engineered for tight spaces and tough conditions. Dual 4-Ohm voice coils provide flexible wiring options for easy amplifier matching and optimized system performance.
Built to perform anywhere, the UV-resistant cone and surround deliver lasting durability in any environment. SoloKon cone technology fuses the cone to the vented back brace, creating a rigid, distortion-free structure that enhances cooling and ensures clean, accurate bass.


Red double stitching reinforces the connection between the Santoprene surround and polypropylene cone for superior durability, while the forced-air cooling system keeps the subwoofer up to 20% cooler—ensuring reliable, long-lasting performance even under heavy loads.
