QPower QBGMC12 2007 HT QBomb Under Seat 12 Inch Subwoofer Enclosure Speaker Box with 5.5 Inch Mount for 2007 to 2013 GMC & Chevy Extended Cab Trucks

Build a powerful bass system with the QPower “QBOMB” Dual 12″ Empty Woofer Enclosure – QBGMC122007HT. Engineered for Extended Cab Chevy Silverado and GMC Sierra trucks from 2007 to 2013 with high transmission humps, this under-seat down-firing enclosure offers a strong foundation for two 12″ subwoofers (sold separately).

Constructed from 5/8″ MDF and carpet-covered for a clean finish, the box includes separate sealed chambers for each woofer, helping maintain air space and tuning without interference. The center-raised bottom design lets the enclosure sit correctly over the transmission hump area without rocking or misalignment.

Perfect for users who want an integrated, out-of-sight bass solution, this QPower enclosure saves space while delivering room for powerful, deep low frequencies when paired with quality 12″ woofers.
