      Description

      Immersive Quad-Driver Bass Performance. This King Boxes enclosure is engineered to unleash the potential of four 8-inch subwoofers by optimizing internal volume and port dimensions for smooth, extended low-frequency output. The front-firing port design focuses the bass energy forward, filling the cabin with powerful, controlled thump.

      Truck-Tough Durability. The charcoal spray finish provides a textured, wear-resistant surface that stands up to cargo shifting and moisture. The robust MDF panels and internal polyfill create a rigid, low-resonance chamber that ensures your subwoofers perform efficiently without box flex.

      Installation. Secure the box in the cargo area with straps or custom brackets, connect each subwoofer to the amplifier using the terminal cup, and tune your system for optimal crossover settings.

      Application. The King Boxes Quad 8-Inch Ported Subwoofer Box fits 2017-2026 Ford F-250 Super Duty SuperCrew models.
