Front-Row Bass Experience

Turn every drive into a live-show experience with powerful low-frequency output powered by 1.40 FT³ of total air space. Each subwoofer operates within its own precision-tuned 0.70 FT³ chamber, delivering tight, balanced, distortion-free bass that stays clean even at high volume. The forward-firing design pushes deep, impactful sound straight into your cabin, creating stronger punch and more even sound distribution throughout your ride.

Full-Length Design. Full-Force Bass.

Stretching a full 58 inches, this extended enclosure maximizes internal air space while fitting cleanly behind your rear seat for a seamless install. Crafted from 5/8" premium MDF, it delivers solid structural strength and consistent acoustic performance you can count on. Professionally sealed with high-grade Titebond silicone, the airtight design enhances bass punch and low-end depth. Wrapped in durable trunk-liner carpet, it offers a rugged, OEM-style finish that looks factory-installed right out of the box.
