Vehicle-Specific Fit

The Q Power QBGMC14212 is an empty dual subwoofer enclosure built for 2014 through current GMC Crew Cab four-door trucks. It provides a dedicated mounting location for two 12-inch drivers without requiring custom fabrication.

Bedliner Coating Finish

The exterior features a bedliner coating that resists scratches and moisture in a truck cabin environment. At 44 lbs the enclosure adds mass that helps reduce panel vibration during normal listening levels.

Empty Enclosure Flexibility

No drivers or amplifier are included so installers can select components that match their power and sound preferences. The box arrives ready for wiring and speaker installation in the factory rear-seat area.

Questions about this item

How is the 12 in empty dual enclosure secured in a 2014-current GMC Crew Cab, and what step is often missed?

The enclosure is designed to fit behind the rear seat of the specific cab; the step often missed is verifying the bedliner coating aligns with factory mounting points before bolting it down.

What maintenance will the 44 lbs bedliner-coated enclosure need over time?

Inspect the bedliner coating periodically for cracks or peeling caused by moisture or cargo abrasion; touch up any damaged spots to prevent rust on the underlying wood.

What limit appears first when the enclosure is driven hard for long periods?

Heat buildup inside the sealed 12 in chambers is the first limit; without active cooling, sustained high output can overheat the subwoofers and degrade performance.
