Powerful Dual Subwoofer Performance

This dual subwoofer enclosure features an 11 1/8" cutout diameter, engineered for a precise and professional fit in your vehicle. With a total air volume of 1.80 ft³ (0.90 ft³ per sub) and a solid 52 lbs design, it delivers deep, rich bass that fills your cabin. The 5" mounting depth (with a 5 1/2” magnet diameter) allows for easy installation while maximizing sound performance.

Spacious Design for Maximum Bass

Measuring 13 5/8" in height and 57 1/4" in length, this dual subwoofer enclosure fits neatly under your vehicle’s rear seat while providing ample internal space. Its tapered design—12 1/2" top depth and 18 3/4" bottom depth—optimizes airflow for richer, deeper bass. Built for both performance and convenience, it delivers powerful sound without compromising interior space.
