Chevy Silverado & GMC Sierra Single Cab Dual 12" Sealed Enclosure (1999-2006) | Armor Coated

Pack massive sound into your Regular Cab without losing your seating. Designed specifically for the 1999-2006 Chevrolet Silverado and GMC Sierra Single Cab (Standard Cab), this custom-fit enclosure slides perfectly behind your seats to house two 12-inch subwoofers.

Utilizing a space-saving wedge design and finished in our rugged "Armor" Spray Liner, this box transforms the often-wasted space behind the driver and passenger into a high-output bass zone.

Vehicle Fitment

• Make: Chevrolet Silverado & GMC Sierra (1500, 2500, 3500)

• Years: 1999 - 2006 (Classic Body Style / GMT800)

• Cab Style: Single Cab / Regular Cab (2-Door)

Key Features

• Dual 12" Capacity: Most single cab boxes only fit 10s. We engineered this enclosure to accommodate Dual 12-inch subwoofers, giving you significantly more cone area and deeper bass output.

• Angled Wedge Design: The box features a slanted face to match the angle of your seats. This allows you to push the seats back further than with a standard square box, maximizing legroom while keeping the subwoofers secure.

• Sealed for Accuracy: The sealed design provides tight, punchy, and accurate bass. In a small cabin like a Single Cab, a sealed Dual 12 setup produces incredible "Cabin Gain," making the bass feel even louder and more physical.

• "Armor" Spray Liner Finish: Coated in a premium Polyurethane Bed-Liner Spray. This finish is water-resistant, scratch-proof, and adds structural rigidity to the MDF, ensuring clean sound without box resonance.

Installation Note

⚠️ Space & Depth: Single Cabs are tight!
