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
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

Maximize your sound without sacrificing space. The low-profile recessed suspension lets the cone reach full excursion with just 0.87" of frontal clearance—even with the grille installed—making it ideal for tight installations. Engineered for big sound from compact enclosures, the shallow mounting depth and exceptional excursion capability deliver smooth, powerful bass. Built to last, the injection-molded, mica-filled polypropylene cone with rubber surround provides durability, moisture resistance, and minimal distortion for crisp, clean audio every time.

Precision Bass, Engineered for Every Space

Experience tight, clean, and articulate bass at any power level with Dynamic Motor Analysis (DMA) optimized design—where proprietary motor, suspension, and cone modeling deliver perfectly linear excursion. The cast-alloy, space-saving frame with flat edges lets you install multiple subwoofers side by side, making it ideal for compact setups without sacrificing performance.

Compact Design, Big American Bass

Engineered for maximum versatility, the 10TW1-2 delivers powerful performance in both sealed and ported enclosures with amplifiers ranging from 75–300 W RMS. Its seriously shallow 4-3/8" mounting depth makes installation in tight spaces effortless. Built in the USA with a cast-alloy frame and innovative “concentric tube” motor structure, this subwoofer minimizes profile without compromising performance—bringing big, clean bass to any setup.
