JL Audio Stealthbox fits Chevy Silverado GMC Sierra beige

Doesn’t not come with JL W3v3 12" 2-ohm subwoofer. This Stealthbox® enclosure fits under the driver side rear seat of 99 2000 2001 2002 Chevrolet Silverado and GMC Sierra Extended Cab pickups. JL Audio Stealthboxes are hand-crafted from fiberglass and/or Advanced Molded Composite (AMC) materials. Fiberglass delivers a level of enclosure rigidity and dimensional stability not possible with other enclosure materials, allowing wall thickness to be reduced compared to a typical wood enclosure. This gives you more interior box volume for a given external volume. Fiberglass and AMC materials are very strong and can be molded into very complex shapes; giving JL Audio the ability to design your Stealthbox to fit perfectly into tight spots and minimize intrusion into your vehicle's useful space. Each Stealthbox is laminated, ground, joined, and finished by hand in the USA. Proprietary techniques and materials developed by JL Audio through years of fiberglass manufacturing experience ensure consistent quality and performance.
