      Description

      Robust Poly‑Coated Construction. Constructed from heavy-gauge 5/8″ Medium Density Fiberboard (MDF), the Dual 8-Inch Down Firing Subwoofer Box; Poly Coated is finished with a high-pressure polyurethane bed liner coating. This poly-coated layer enhances durability by resisting moisture, scuffs, and vibration fatigue, common challenges in environments. According to product listings, this armor coating stiffens the wood and eliminates air leaks, resulting in improved bass response and long-term structural integrity.

      Optimized Acoustics via Down‑Firing Design. The Dual 8-Inch Down Firing Subwoofer Box; Poly Coated takes advantage of acoustic coupling with the Sierra 2500 HD Crew Cab’s floor, enhancing low-frequency output and creating a deeper, more resonant bass experience. This design minimizes enclosure volume while maximizing sound quality, making it ideal for vehicle interiors where space is limited but audio performance is still a priority.

      Ready For Clean Wiring & Integration. The Dual 8-Inch Down Firing Subwoofer Box; Poly Coated comes equipped with pre-cut subwoofer mounting holes and sealed terminal cups for clean wiring. Its rugged poly-coated finish allows for installation without additional carpet wrapping, offering a sleek, utilitarian look that matches the Sierra 2500 HD Crew Cab’s interior. Whether you’re a professional installer or a seasoned DIYer, the plug-and-play nature of this box simplifies integration into your audio system.

      Installation. Putting this Dual 8-Inch Down Firing Subwoofer Box; Poly Coated on your Sierra 2500 HD Crew Cab takes 1 hour to install.

      Warranty. There is a 1-year limited warranty on this product.

      Application. The Dual 8-Inch Down Firing Subwoofer Box; Poly Coated fits 2020-2026 Sierra 2500 HD Crew Cab models.
