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.

In Flat Design

MUSWAY is known for its small and at the same time very powerful products. The two new flat subwoofers also join this tradition. Due to their design, they also suitable for installation locations that have little space in depth when shallow installation dimensions are a must. With an installation depth of 78 mm for the 8" (20 cm) and a sensationally low 87 mm for the 10" (25 cm) subwoofer, they are the ideal problem solvers for special installations.

High Quality Materials

A particularly flat subwoofer should of course sound good and must be robust. That is why MUSWAY uses special and very hard cones made of the composite materials glass fiber and carbon . No savings were made on the drives either: the woofers have 40 or 45 ounce magnets and are driven by 50 mm dual voice coils, which are also very long wound. With Xmax values ??of +/- 15 mm, both woofers ensure a decent stroke. With 250 or 300 watts RMS, they are also very resilient, so that no compromises have to be made.
