Description
Dual 12″ Speaker Capacity for Serious Low End. This Dual 12-Inch Down Firing Subwoofer Box; Carpeted is purpose-built to house two 12-inch subwoofers in a down-firing configuration, delivering powerful bass response that resonates throughout the cabin. The down-firing orientation enhances acoustic coupling with the floor, allowing low frequencies to reflect and fill the interior space. This setup produces a deep, immersive bass experience that’s felt as much as heard-perfect for audio enthusiasts who want serious low-end performance in their Silverado.
Quality Construction & Carpeted Finish. Constructed from 5/8-inch medium-density fiberboard (MDF), the Dual 12-Inch Down Firing Subwoofer Box; Carpeted offers excellent rigidity and acoustic stability, minimizing unwanted vibrations and resonance. The exterior is wrapped in automotive-grade carpet that blends seamlessly with the factory interior of your 2001–2006 Silverado 3500 HD Crew Cab. The down-fire design keeps the subwoofers protected while allowing bass to radiate effectively into the cabin-without requiring bulky enclosures or sacrificing rear-seat space.
Optimized Air‑Volume & Depth. Each chamber of the Dual 12-Inch Down Firing Subwoofer Box; Carpeted provides approximately 0.77 cubic feet of internal air volume, which is ideal for many sealed-box subwoofer designs. With a mounting depth of about 6.25 inches, the box accommodates a wide range of performance 12-inch subwoofers while maintaining a low-profile footprint. This makes it easy to tuck under the rear seat or integrate into the Silverado 3500 HD Crew Cab’s interior without interfering with passenger comfort or cargo space.
Installation. Putting this Dual 12-Inch Down Firing Subwoofer Box; Carpeted on your Silverado 3500 HD Crew Cab takes 1 hour to install.
Warranty. There is a 1-year limited warranty on this product.
