Big Bass for Your Tundra Without Losing Space

The Ground Shaker GS-DTOYP112B is built for Toyota Tundra Double-Cab owners who want powerful bass while keeping their truck interior clean and functional. Designed to fit perfectly under the rear seat of 2007–2021 Toyota Tundra Double-Cab models, this enclosure delivers strong low-end performance without taking up valuable cabin space. Its upward-firing design helps spread bass evenly throughout the truck, giving your music a fuller and harder-hitting sound every time you turn up the volume.

Tuned for Deep, Clean Low-End Performance

With a tuned frequency of 35 Hz and 0.72 ft³ of internal air volume, this ported enclosure is designed to produce deep, punchy bass with excellent low-frequency extension. The precision-engineered slot port improves airflow for cleaner output and reduced port noise, while the 11 1/8" cutout and 4 3/4" mounting depth make it compatible with many popular 12-inch subwoofers. Whether you’re listening to hip-hop, rock, EDM, or country, this box delivers tight and responsive bass that makes every drive more enjoyable.

Built Tough for Daily Use

Constructed from durable 5/8" high-quality MDF wood, the GS-DTOYP112B is made to stay solid even during heavy bass sessions. Premium Titebond wood glue and airtight silicone sealing help reduce unwanted vibrations and air leaks for cleaner sound performance. The rugged trunk liner carpet finish gives the enclosure a factory-style appearance while protecting it from daily wear and tear. A sturdy binding post terminal provides secure speaker connections for an easier and more reliable install. Just note, this enclosure is not compatible with Crew-Max models.

 

 

Big Bass, Small Package

Perfect for tight spaces, this subwoofer features a compact 4-3/8" shallow-mount design that allows near-full forward cone excursion with minimal clearance. Engineered for small enclosures, it delivers smooth, deep, and powerful bass without compromising on sound quality—proving that great things do come in small packages.

Durable, High-Performance Bass

Built to last, this subwoofer features an injection-molded, mica-filled polypropylene cone with a rubber surround for low distortion and moisture resistance. DMA-optimized motor and suspension design ensures linear excursion, tight, clean bass, and consistent output at all power levels—delivering reliable, high-quality performance every time.

Compact Frame, Powerful Flexibility

Maximize installation options with a cast-alloy, space-saving frame featuring flat edges for tight side-by-side mounting. Designed for versatility, this subwoofer pairs seamlessly with amplifiers ranging from 75–300 W RMS, delivering powerful, clean bass no matter your setup.
