SSBOXES Chevy/GMC Extended & Double Cab Quad 8 Subwoofer Box

SSBOXES Chevy/GMC Extended & Double Cab Quad 8 Subwoofer Box

This SSBOXES quad 8 subwoofer enclosure is built for Chevy and GMC truck owners who want a strong under-seat bass box for an extended cab or double cab truck setup.

This listing is for the subwoofer box only. It is designed for four 8 inch subwoofers and is intended for Chevy Silverado and GMC Sierra extended/double cab trucks with the middle hump under the rear seat.

Vehicle Fitment

Fits many Chevy Silverado 1500 extended cab / double cab and GMC Sierra 1500 extended cab / double cab trucks, especially later body styles commonly searched as 2014+ Chevy/GMC double cab.

Also fits select older Chevy Silverado 2500/3500 and GMC Sierra 2500/3500 extended cab models that have the center hump / middle hump under the back seat.

Important fitment note: Chevy and GMC cab floors changed across years and models. Please confirm your truck has the correct rear-seat floor shape with the middle hump before ordering. This is especially important for older Chevy/GMC HD trucks and OBS-style searches.
