      Description

      Space-Saving Bass Solution. The Rhino Box Behind Seat Subwoofer Box is a compact yet powerful enclosure engineered for tight installations behind seats. Designed for a single 12-inch subwoofer, it delivers clean and responsive bass while maximizing cabin space. It’s ideal for truck and coupe owners seeking deep sound without compromising passenger comfort or storage.

      Construction and Appearance. Built from 3/4-inch MDF and finished with a rugged matte black poly coating, this box is highly resistant to wear, moisture, and vibrations. The internal polyurethane bed liner strengthens the structure and prevents air leaks, while the sleek exterior adds a professional appearance. Measuring 21.06 inches wide, 3.62 inches deep at the top, 7.95 inches deep at the base, and 14.76 inches high, it is precision-sized for low-profile installs.

      Installation. This subwoofer box is designed for behind-the-seat placement and integrates easily into most vehicle cabins. Its slim profile makes it ideal for spaces with limited clearance, and the solid construction ensures optimal bass output without distortion. No modifications are needed to incorporate it into a custom audio system, making setup simple and effective.

      Application. This Rhino Box Behind Seat Subwoofer Box is a universal fit. It enhances your vehicle’s sound system by delivering powerful low-end performance in a space-conscious design. Perfect for discreet audio upgrades, it combines durability, style, and functionality in one compact enclosure.
