Chevy Silverado & GMC Sierra Crew Cab "Quad 8" Ported Front-Fire Enclosure (2019-2024) | Armor Coated

Turn your Crew Cab into a bass machine with this custom-engineered Quad 8-inch Ported Enclosure. Designed specifically for the 2019-2024 Chevrolet Silverado and GMC Sierra Crew Cab, this box maximizes the under-seat area to house FOUR 8-inch subwoofers, delivering a level of output and punch that standard dual setups just can't match.

Featuring a high-output ported design and a Front-Firing configuration, this enclosure projects bass directly into the cabin for a visceral, hard-hitting audio experience.

Key Features

• Quad 8" Performance: Running four 8-inch subwoofers gives you the best of both worlds: the tight, fast transient response of smaller drivers, combined with massive total cone area (more than two 12s!) for high volume levels.

• Front-Firing Impact: Unlike down-firing boxes that push sound into the carpet, this enclosure fires the subwoofers forward from under the seat. This direct path results in cleaner, louder bass that you can feel in your chest.

• Ported for Power: The ported (vented) design maximizes the efficiency of the four drivers, allowing them to play deeper and louder than sealed alternatives.

• "Armor" Spray Liner Finish: Coated in a premium Polyurethane Bed-Liner Spray. This finish is rugged, water-resistant, and scratch-proof. It creates a seamless, professional look that matches the utility of your truck and won't peel like carpet.
