Ground Shaker
Dual Chambers, Maximum Punch

Experience tight, punchy bass that fills your ride even in compact spaces. Dual precision-tuned chambers keep each subwoofer’s sound clean, powerful, and distortion-free. Engineered for forward-firing audio projection, it directs every low-end pulse straight into your cabin for maximum impact.

Compact Strength, Full-Bodied Sound

With 1.27 cubic feet of optimized airspace, this enclosure delivers responsive, rich bass that perfectly fills small to mid-size interiors. Crafted from rugged 5/8" MDF, it offers long-lasting strength and durability built for the road. The carpeted trunk-liner finish gives a professional, factory-quality look while protecting the enclosure from wear.

Dual binding post terminals make installation fast, secure, and professional-grade. Designed with a forward-firing layout, it fits neatly behind the rear seat of 2007 old-body style vehicles, accommodating minor adjustments to air ducts, the factory jack, and back panel carpet.
