QPower SB412T

The QPower SB412T is a heavy-duty, truck-specific enclosure designed to turn the unused space behind or under a seat into a high-output bass station. Built with the “Q-Bomb” philosophy, this box features a ruggedized Black Bedliner Spray finish, making it virtually indestructible and immune to the scuffs, moisture, and wear-and-tear of a hard-working truck cabin.

QPower SB412T | 12″ Dual Subwoofer Truck Enclosure

Application: Universal Fit for Single Cab, Crew Cab, and Extended Cab Trucks Configuration: Dual 12″ Sealed Slim-Line Enclosure

The SB412T is engineered for “Shallow-Mount” or “Slim-Line” subwoofers. By utilizing a Wedge-Style design, QPower has maximized the internal air volume while maintaining a thin profile that fits behind most bench seats or under rear bench seats. Unlike standard carpeted boxes that can mold or tear in a truck environment, the Q-Bomb Bedliner finish ensures this enclosure remains airtight and structurally sound for the life of the vehicle.
