GS-DTOY210B Sub Box
Under-Seat Sub Box – Clean Factory Look with Hard-Hitting Bass

The Ground Shaker GS-DTOY210B is designed for truck owners who want deep, punchy bass without losing cabin space. Built to fit neatly under the rear seat, it keeps your install clean and hidden while still delivering strong in-cabin bass thanks to its upward-firing design. Perfect for daily driving, it gives you that low-end punch you can feel without cluttering your truck interior.

Built Tough for Real-World Bass Performance

Constructed from 5/8" high-quality MDF wood, this enclosure is made to stay solid even under heavy bass pressure. It’s carefully assembled using premium Titebond wood glue and sealed with Titebond silicone to keep the box airtight, helping produce tighter and more accurate low-frequency response. The durable trunk liner carpet finish also protects the box while giving it a clean, factory-style look.

GS-DTOY210B Sub Box
GS-DTOY210B Sub Box
Simple Install, Clean Wiring, Strong Output

With dual binding post terminals, wiring your subs is quick, secure, and hassle-free. The compact under-seat layout keeps your truck functional while still upgrading your entire sound system with real bass impact. Just note—this enclosure will not fit Crew-Max models, but for compatible trucks, it’s a solid upgrade that brings clean design and serious low-end performance together.

 

 

Big Bass, Small Footprint

The TW3’s 10" shallow-mount design (3.25" depth) delivers deep, powerful, and articulate bass in tight spaces. Its mica-filled polypropylene cone ensures durability and minimal distortion, while a satin black aluminum-alloy dust cap with JL Audio logo adds heat dissipation and a premium look.

Clean, Powerful Bass in a Compact Design

DMA-optimized motor, suspension, and cone deliver tight, linear bass at all power levels. The cast-alloy frame with tab-ear mounting maximizes cone area while maintaining strength. Dual 8-ohm voice coils provide flexible wiring, and the sub works seamlessly in sealed or ported enclosures with 200–400W RMS amplifiers.

Slim Design, Big Bass

The heavy-duty rubber surround supports large cone excursions for maximum airflow and deep, powerful bass. JL Audio’s engineering ensures a slim, shallow-mount design that delivers impressive sound and reliability, ideal for tight spaces without sacrificing cargo or passenger room.
