QBGMC122014DCAB

The Q Power QBGMC122014DCAB is a dual 12-inch sealed under-seat enclosure designed specifically for 2014+ Chevrolet Silverado and GMC Sierra Double Cab trucks. Its down-firing design helps protect the subwoofers while improving low-frequency response and preserving usable cabin space.

Unlike many generic prefab truck boxes, this enclosure is vehicle-specific and shaped to fit cleanly under the rear seat of Double Cab/Extended Cab GM trucks. It uses a rugged sprayed bedliner finish instead of carpet, making it more durable for work trucks and daily-driver abuse.
