Custom-Fit Dual 12-Inch Toyota Subwoofer Enclosure

The Ground Shaker GS-DTOY212B dual 12-inch subwoofer enclosure is engineered specifically for select Toyota trucks, providing a vehicle-specific solution that delivers powerful bass without sacrificing valuable cabin space.

This combination minimizes unwanted vibrations and air leaks, resulting in tighter bass, improved sound quality, and enhanced subwoofer efficiency. The durable carpeted trunk-liner finish also adds protection while blending seamlessly with your vehicle's interior.

Upgrade Your Toyota Truck Audio System with the GS-DTOY212B

Whether you're upgrading your daily driver or building a high-performance car audio system, the Ground Shaker GS-DTOY212B provides an ideal foundation for dual 12-inch subwoofers. Its custom-fit design, rugged construction, and optimized sealed enclosure configuration make it a top choice for drivers looking to achieve powerful bass, improved audio clarity, and reliable long-term performance from their Toyota truck sound system upgrade.

 

 

Compact Design, Powerful Bass

Maximize bass performance in tight spaces with a recessed suspension that allows full cone excursion within the frame, needing just 0.87" of frontal clearance. Engineered for small enclosures, its shallow mounting depth and high excursion capability deliver smooth, powerful bass from compact boxes. The injection-molded, mica-filled polypropylene cone with rubber surround ensures long-lasting durability, moisture resistance, and minimal distortion for crisp, clean sound.

Precision Bass in a Space-Saving Design

Enjoy tight, clean, and powerful bass at any volume with DMA-optimized design—featuring proprietary motor, suspension, and cone modeling for perfectly linear excursion. The cast-alloy, space-saving frame with flat edges allows multiple subwoofers to be installed side by side, maximizing performance without taking up extra space.

Compact, Versatile, and Built for Performance

Engineered for adaptability, this subwoofer delivers powerful bass in both sealed and ported enclosures, supporting amplifiers from 75–300 W RMS. Its compact 4-5/8" mounting depth makes installation in tight spaces effortless, while the innovative concentric tube suspension design minimizes profile without sacrificing performance—bringing big, clean bass from a small package.
