Clean Truck Bass Upgrade That Hits Hard

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.

Built Strong for Daily Bass Performance

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.

Clean Install, Factory Look, Serious Output

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.

Enhanced Bass Performance

Superior Durability

Built with Forced-Air Cooling™, a ribbed polyurethane surround, and signature yellow surround stitching, this subwoofer ensures outstanding durability and long-lasting performance.
