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.
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.


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.

Experience powerful, high-performance sound with the 12-inch woofer, featuring a versatile 2 or 4 SVC impedance, handling up to 900 watts of peak power. Designed for ultimate clarity and punch, it delivers an impressive frequency response of 25-500 Hz and a sensitivity of 87.1 dB @ 1W, 1m, making it the perfect choice for those seeking deep, distortion-free bass and exceptional amplifier compatibility (225-450 watts RMS).
Achieve superior sound quality with this subwoofer, optimized for both sealed and ported enclosures, and delivering a powerful 450 watts RMS. Featuring individual voice coils for precise audio control and a unique red wrap stitching that seamlessly connects the surround to the modified radius cone, this subwoofer ensures distortion-free bass. The innovative SoloKon design merges the woofer and rear mount into one unified system, providing unmatched performance and reliability.


Unleash powerful, deep bass with advanced features like the optimized motor design and KICKER forced air cooling system, ensuring both strong performance and efficient cooling. The slim, shallow-mount design offers easy installation, while the heavy-duty stamped steel basket reduces vibration for clearer sound. Enjoy distortion-free bass with the high-temperature voice coil, and experience enhanced audio performance thanks to the injection-molded woofer cone, which moves hundreds of times per second for crisp, dynamic sound.
