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 unmatched audio performance with a powerful 450W RMS output, delivering deep, clean bass that elevates any sound system. The space-saving shallow mount design allows for flexible installation in tight or custom-fit locations—perfect for trucks, boats, or compact vehicles. Built to last, the rugged die-cast aluminum basket not only enhances structural integrity but also helps dissipate heat for consistent, reliable performance even at high volumes.
Built for performance and reliability, this subwoofer features a high-strength foam surround for clean bass, a 2″ 4-layer voice coil for high power handling, and a FEA-optimized motor for efficient output. Tinsel woven leads on a Nomex spider enhance durability, while Dual 4-Ohm or Dual 2-Ohm impedance options offer flexible wiring setups.
