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.

 

 

Produce Heart-pounding Bass

A car subwoofer with a shallow-mount design and many impressive features, the JL Audio 12TW3-D4 is the perfect upgrade for your car's factory subs. This 12-inch subwoofer can put in some heart-pounding bass and would not need too much space to be installed inside your vehicle.

Mica-filled Polypropylene Cone

The JL Audio 12TW3-D4 has a mica-filled polypropylene cone and a rubber surround, which gives the subwoofer the needed rigidity and durability to withstand the effects of extended usage at high volume levels while being able to produce an accurate bass response with only minimal distortion.

 

Clean Bass With Reduced Distortion

It uses JL Audio's DMA-optimized motor design, which helps reduce distortion while producing a clean and punchy low-frequency performance. The JL Audio 12TW3-D4 also has the company's famous Concentric Tube Suspension, which significantly improves the subwoofer's excursion, allowing for more air pressure and resulting in louder and better bass performance.
