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.

 

 

Big Bass in Tight Spaces

The 8W1v3-4 delivers powerful JL Audio bass where traditional subs won’t fit, bringing legendary W7 technologies—advanced cone bonding, precise motor assembly, and optimized suspension—to compact vehicles. Engineered for impressive output and accurate sound at moderate power levels, it’s perfect for small enclosures in trucks, sports cars, and compact vehicles.

 

 

Clean, Powerful Bass

DMA-optimized motor and suspension deliver tight, articulate bass with minimal distortion across all power levels. The mica-filled polypropylene cone with rubber surround and aluminum dust cap ensures strong, crisp lows and features a stylish embossed JL Audio logo.

 

 

Compact, Customizable, Powerful

With a shallow 3-7/8" mounting depth, the 8W1v3-4 fits compact spaces and small enclosures from 0.35cuft. The removable trim ring can be painted for a custom look, and optional grille inserts add style and protection. Compatible with sealed or ported enclosures and 50–100W RMS amplifiers, it delivers flexible, powerful bass for budget-friendly setups.

Compact, Affordable, Reliable

Optimized for small vehicles and tight spaces, the 8W1v3-4 delivers impressive low-end performance without the bulk of larger subs. JL Audio engineering ensures dependable, high-quality sound at an accessible price.
