Q Power QBGMC07212 12 in QBOMB Dual GMC 2007-2013 Crew Cab Under Seat car subwoofer

Vehicle-Specific Fitment

The Q Power QBOMB enclosure is built for 2007 to 2013 GMC crew cab trucks and tucks beneath the rear seat. Dual 12 inch drivers are housed in a single box that uses the factory space without cutting or drilling.

Single-Cab Limitation

This enclosure only fits the crew cab body style; regular and extended cab models lack the under-seat volume required. The fixed port tuning and internal bracing are calculated for that exact cavity, so swapping to another truck chassis will change the response.

Dual-Driver Output

Two 12 inch cones move more air than a single driver, giving stronger low-frequency output at moderate amplifier power. The sealed 49 lb box reaches its mechanical limits before a larger ported design would, so extreme SPL competitors will need a custom build.
