Upgrade your truck's bass without sacrificing space with the NVX VE-GM-SLVECG2-D12S, a dual 12-inch sealed down-firing subwoofer enclosure custom built for 2008–2013 Chevrolet Silverado and GMC Sierra Extended Cab trucks. This enclosure is the perfect blend of precision, performance, and durability. It's CNC-cut for exact vehicle fitment and hand-assembled to ensure flawless craftsmanship. Constructed from 3/4" MDF, it's built to withstand the rigors of the road while delivering rock-solid sound reproduction. The down-firing sealed design helps protect your subwoofers from accidental damage while enhancing low-end response by coupling the bass with the cabin floor. Internally, each chamber provides 0.5 cubic feet of air space, making it ideal for compact or shallow-mount subs. Finished in premium carpet, this enclosure looks as good as it performs—blending perfectly into your truck's cabin. With 4.75” mounting depth and 11-1/8” cutouts, it's ready for your next custom audio build.
