QPower Qbomb 12" ported enclosure

The QPower Qbomb is a new ported subwoofer enclosure built for 2014 to 2018 GMC Crew Cab four-door trucks. It houses two 12-inch drivers in an upfire underseat layout finished with durable bed liner. Each chamber provides one cubic foot of air space and is tuned to 38 Hz with a five-inch mounting depth.

Buyers needing a direct-fit bass solution

This enclosure suits owners who want a vehicle-specific box that installs under the rear seat without modification. It is not for drivers of other cab styles, model years outside the 2014 to 2018 range, or installations that require a sealed alignment or a different tuning frequency.

Questions about this item

Will the 38 Hz tuning frequency hold up during long listening sessions?

The enclosure is tuned to 38 Hz and maintains that alignment as long as the subs stay within their thermal limits; sustained high output can shift the effective tuning if the voice coils overheat.

How much heat builds up in the bed-liner finish when the box runs all day?

The bed-liner coating is a passive surface and does not generate heat; any warmth comes from the subwoofers themselves and is dissipated through the 1 cubic foot air space per sub and the 5 inch mounting depth.
