Check Vehicle and Subwoofer Fitment

Before ordering, measure the available space behind your truck seat and compare it with the enclosure dimensions. Leave room for seat adjustment, wiring, and the subwoofer’s cone and surround.

Match your subwoofer’s mounting requirements to the 5-inch mounting depth and 11.125-inch cutout diameter. Check that the manufacturer’s recommended sealed enclosure volume is compatible with this box, accounting for subwoofer displacement when determining usable air space.

Fitment depends on your truck’s cab layout, seat position, and subwoofer selection.
