      Description

      High‑Output Enclosure Built for Serious Bass Systems. The Quad 12‑Inch Double Ported Subwoofer Box; Poly Coated is engineered for enthusiasts who demand massive air movement and deep, resonant low‑frequency performance. Designed to house four 12‑inch subwoofers, this enclosure provides the internal volume and port tuning needed for high‑output bass setups. Retail listings confirm this is a universal enclosure that may require adaptation depending on the vehicle and installation layout.

      Dual Ported Chambers for Maximum Airflow and Efficiency. Featuring a double‑ported design, the Quad 12‑Inch Double Ported Subwoofer Box; Poly Coated enhances bass response by allowing each chamber to move air efficiently. This improves low‑end extension, reduces distortion, and increases overall output, making it ideal for SPL‑focused builds or large‑scale audio systems.

      Poly Coated Exterior for Superior Durability. The enclosure is finished with a rugged poly coating that protects the MDF structure from moisture, abrasion, and long‑term wear. This coating adds stiffness to the wood, reduces the risk of air leaks, and ensures the box maintains structural integrity even under extreme sound pressure. Poly‑coated enclosures are known for their enhanced durability and improved acoustic performance, as seen in similar high‑pressure polyurethane‑coated designs.

      Heavy‑Duty MDF Construction for Clean, Controlled Bass. Built from thick MDF panels, the Quad 12‑Inch Double Ported Subwoofer Box; Poly Coated provides the rigidity needed to handle the intense vibrations produced by four large subwoofers. MDF remains the industry standard for subwoofer enclosures due to its density, stability, and ability to deliver clean, accurate bass reproduction.

      Installation. Putting this Quad 12-Inch Double Ported Subwoofer Box; Poly Coated on your vehicle takes 1 hour to install.

      Warranty. There is a limited warranty on this product.

      Application. The Quad 12-Inch Double Ported Subwoofer Box; Poly Coated offers universal fitment.
