      Description

      Dual-Chamber Bass Power. This King Boxes enclosure houses two 12-inch drivers in separate sealed chambers, delivering tight, impactful bass that remains punchy and controlled in the mid-30 Hz range without the boominess common to ported designs.

      Rugged, Low-Profile Design. Built from high-density MDF and finished with a charcoal-textured spray coat, the box resists moisture and abrasion. Its low height allows placement under the rear bench or behind the cab without sacrificing interior space.

      Installation. This product installs by sliding into the rear cab area or under the seat, securing with straps or brackets, and wiring to an amplifier—no permanent modifications required.

      Application. This King Boxes 12-Inch Dual Sealed Subwoofer Box; Charcoal Sprayed Finish fits 2003–2006 Silverado 1500 Crew Cab rear seating or under-seat locations.
