OEM-Fit Bass Upgrade, No Cargo Compromise

We are an official Kicker distributor, and this enclosure is purpose-built for the stock B&O sub location behind the passenger-side cargo panel. The Bronco 8″ Round Subwoofer Enclosure delivers tight, musical bass while keeping your gear space fully usable. It’s available for both 4 Door Ver. and 2 Door Ver. models, so you get a clean, factory-style upgrade without cutting panels or losing storage.

Each unit is 3D printed in the USA and made to order, with a typical 3–4 day turnaround. The speaker opening is precision-sized for the Kicker CompRT 8″ (7″ diameter hole) and can be opened with a die grinder for other brands.

If you order just the box from us, it will not include threaded inserts for the speaker.
