Frequently Asked Questions (FAQ)


The BE-FRD-BRO-G6 is custom-molded for the 2021-Up Ford Bronco (4-Door). Unlike universal boxes that slide around or block the rear window view, this B.O.O.S.T. box bolts into the passenger-side rear cargo panel for a factory-seamless look.
The sealed design is perfect for the Bronco's open-cabin acoustics, providing tight, punchy bass that doesn't get "muddy" when the top is off. It offers a more compact footprint than ported boxes, which is vital for maintaining off-road gear space.
The enclosure is wrapped in OEM-matching automotive carpet. While the hand-laid fiberglass shell is moisture-resistant, the carpet can stain or hold odors if soaked. We recommend installing an NVX heavy-duty cargo liner to protect the area from spills.
No. This enclosure is engineered to fit into the existing cavity of the rear quarter panel. It is shaped to ensure you still have full access to the floor storage cubby and does not interfere with the factory 12V power points or tie-down hooks.
Yes, adding polyfill can help the internal 10" subwoofer perform as if it were in a slightly larger space. To get the best performance from the pre-loaded driver, pair it with an NVX VAD10001 amplifier for clean, reliable power.
The hand-laid fiberglass is much stronger and more rigid than standard MDF, preventing enclosure flex. To stop the Bronco's metal body panels from rattling, we highly suggest applying NVX SDTK8 sound damping to the inner fender before mounting.
