Dual Subwoofer Power, Perfect Fit

This dual subwoofer enclosure features a 7 1/8" cutout diameter and two individual chambers, each with 0.89 ft³ of air volume, delivering deep, punchy bass. With a total air volume of 1.78 ft³ and a sturdy 40 lbs build, it provides powerful sound without taking up extra space. The 6 3/4" mounting depth allows for easy installation while maximizing bass performance for every ride.

Spacious Design, Big Bass

Measuring 8 1/4" in height, 54 1/4" in length, and 13 1/2" in depth, this dual subwoofer enclosure fits neatly under your vehicle’s rear seat for a sleek, factory-style look. Its generous internal space maximizes airflow, producing richer and deeper bass. Designed for both performance and convenience, it delivers powerful sound without compromising cabin space.

Built Tough, Sound Perfect

Constructed from 5/8" high-quality MDF wood, this dual subwoofer enclosure ensures long-lasting durability and stability. Its rugged trunk liner carpet finish, sealed with premium Titebond silicone and glued with Titebond wood glue, creates an airtight design for deep, distortion-free bass. Equipped with 2 binding post terminals, it delivers reliable connections and consistently powerful, crystal-clear sound.
