Driver-Side Bass, Perfected for Your Truck

Designed specifically for the driver’s side, this enclosure slides snugly under the rear seat, giving your truck a seamless, factory-finished appearance. Dual 0.63 ft³ chambers optimize airflow for each subwoofer, delivering punchy, balanced bass that fills the cabin with precision. Its down-firing design sends deep, powerful lows directly toward the floor, creating an immersive audio experience that turns every drive into a concert on wheels.

Built Tough, Looks Factory-Perfect

Wrapped in rugged trunk-liner carpet, this enclosure not only shields your subwoofers but blends seamlessly with your truck’s interior for a clean, factory-style finish. Constructed from 5/8" premium MDF and reinforced with professional-grade Titebond glue, it stays rock-solid to eliminate vibration, delivering long-lasting durability and precise, distortion-free bass.
