Ground Shaker
Double the Bass, Double the Impact

Turn your truck cabin into a concert-like experience with two independent chambers delivering deep, booming bass that hits every drive with power. Each subwoofer enjoys a precision-tuned 0.89 cubic-foot chamber for clean, distortion-free lows, while the total 1.78 cubic-foot design provides massive, room-filling sound without taking up extra space.

Under-Seat Bass, Built to Last

Slide this compact enclosure neatly under your rear seat for a clean, factory-style look without sacrificing sound quality. Built from 5/8" high-quality MDF and wrapped in rugged trunk-liner carpet, it’s designed to withstand the wear and tear of daily truck life. High-quality Titebond silicone creates a fully sealed chamber, delivering pure, deep bass that transforms every drive into a powerful audio experience.
