99 - 06 GMC/Chevy CREW CAB Rear seat box

This is a Custom-Fit Dual 12-Inch Sealed Enclosure, specifically engineered for Chevrolet Silverado and GMC Sierra Crew Cab pickups. Designed to utilize the often-wasted space behind the rear seat, this enclosure delivers massive bass without sacrificing an inch of your legroom or under-seat storage.

The Ultimate Stealth Upgrade

Finding space for a high-performance audio system in a truck can be a challenge. This enclosure is precision-contoured to fit the specific cab geometry of your Chevy or GMC, allowing you to hide two full-sized 12" subwoofers directly behind the bench seat. It’s the perfect solution for a "stealth" install that keeps your interior looking factory-clean.

Key Performance Features

• Vehicle-Specific Geometry: Engineered to fit the narrow clearance behind the rear seat of Silverado/Sierra Crew Cabs, ensuring the seat still clicks into place securely.

• Sealed "Punchy" Bass: The sealed chamber design provides the tight, accurate bass response needed for rock, country, and hip-hop, ensuring your subs don't sound "muddy" in the small cabin of a truck.

• Industrial Bedliner Armor: Forget about thin carpet that peels or holds dust. This box is fully coated in a rugged, textured bedliner that is moisture-resistant, scratch-proof, and easy to clean.

• CNC-Cut MDF Construction: Built from high-grade Medium Density Fiberboard (MDF) for maximum structural integrity and zero cabinet resonance.

Technical Specifications

Built for the Long Haul

Trucks are work vehicles, and your gear should be able to keep up. By using a bedlined finish instead of traditional carpet, this box is protected against the humidity and temperature swings common in vehicle cabins. The front-firing configuration ensures that the sound energy is directed right into the back of the seat, creating a tactile bass experience you can feel through the upholstery.

Installation Note: Due to the slim profile behind the seat, this enclosure is typically optimized for shallow-mount 12" subwoofers. Please check your subwoofer's mounting depth to ensure a perfect fit.
