CNC-machined HDPE block off plate designed to seal the factory B&O subwoofer opening in the rear wall of your 2021+ Ford F-150, Lightning, or 2023+ Super Duty. When you remove the factory Bang & Olufsen subwoofer to install an aftermarket subwoofer system, the opening in the rear wall is left exposed to the exterior - allowing dust, road debris, and exhaust fumes into the cab. This plate seals that opening.

Each plate features pre-marked alignment circles for easy positioning. Drill 1/8-inch mounting holes and secure with the included zinc coated screws.

Single plate - not a pair. Required when removing the factory B&O subwoofer for an aftermarket upgrade.

CNC-machined from solid-core virgin HDPE in Mount Juliet, Tennessee. Ford, F-150, Lightning, Super Duty, and Bang & Olufsen are registered trademarks of their respective owners. Used for compatibility reference only.
