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.
To create great bass, you need the best in materials and engineering. Alpine's S-Series subwoofers apply technology from their higher end subs to bring you the depth and punch that'll make your tunes come alive.
And to make things even better, these subs are about an inch shallower than their predecessors, making them great candidates for locations where regular high-power subs won't fit.
The S-W8D4 8" subwoofer can handle up to 300 watts RMS, so you can drive it hard without any worries. The tough Kevlar® treated cone stays rigid under pressure, while its rubber High Amplitude Multi-Roll (HAMR) surround enables maximum excursion for impressive performance.
Its dual 4-ohm voice coils allow for extra wiring flexibility, which helps if you plan on adding another subwoofer down the line. Also, it rocks in both sealed and ported boxes, so you can choose an enclosure that suits your tastes.
