      Description

      Immersive Bass Without Sacrificing Space. The King Boxes 10-Inch Dual Downfire enclosure is engineered to deliver powerful, room-filling low frequencies while keeping your extended-cab Silverado’s under-seat area unobstructed. By firing the drivers downward into the cabin floor, it creates a natural subwoofer effect that blends seamlessly with factory sound systems. Ideal for audiophiles who need serious bass on the go, this compact design preserves both cargo space and passenger comfort without compromising acoustic performance.

      Precision Construction for Distortion-Free Sound. Built from high-density MDF and reinforced with internal bracing, this sealed box resists panel flex and unwanted resonance. The charcoal spray finish matches OEM plastic textures and resists scuffs, while the flush-mount terminal cup provides a tidy connection point for speaker wires. Backed by a one-year warranty, this enclosure arrives ready to pair with quality 10-inch drivers and aftermarket amplifiers for a turnkey bass upgrade.

      Installation. This product installs beneath the rear seat using factory mounting points—route speaker leads to the terminal cup and secure the enclosure with the included hardware.

      Application. This King Boxes 10-Inch Dual Downfire Sealed Subwoofer Box; Charcoal Sprayed Finish fits 1999–2006 Silverado 1500 Extended Cab Models.
