Under-Seat Bass Beast: Compact Design, Massive Impact

This compact powerhouse delivers deep, impactful bass in a low-profile, space-saving enclosure designed to fit neatly under your rear seat. With an optimized 0.88 ft³ air volume, it maximizes low-frequency output for tight, distortion-free sound. The precision 7 1/8" cutout ensures a secure, vibration-free fit, giving your subwoofer consistent, professional-grade performance every drive.

Shallow Fit, Big Bass Performance

Designed with a shallow 6" depth and 5 1/2” magnet clearance, this enclosure fits perfectly in tight under-seat spaces without compromising sound. Crafted from premium 5/8" MDF and sealed with Titebond silicone, then reinforced with Titebond wood glue, it delivers long-lasting strength and durability. Wrapped in a professional trunk-liner carpet, it not only protects against wear and tear but also adds a sleek, factory-style finish to your vehicle’s interior.
