CNC-machined HDPE block off plates designed to seal the factory access panel in your 2015-2020 F-150 or 2017-2022 Super Duty doors. Whether you are running factory speakers or aftermarket upgrades, the original access holes in the inner door skin allow bass energy to escape and let road noise enter the cabin. Sealing them creates a semi-sealed chamber behind the speaker for tighter bass response and a quieter ride.

Each plate features pre-marked alignment circles for easy positioning. Drill 1/8-inch mounting holes, apply the included foam gaskets, and secure with the provided zinc coated screws. About 30 minutes per door.

Front plates fit Regular Cab, SuperCab, and SuperCrew.
Rear plates fit SuperCrew only.
If you have a SuperCab, see our separate SuperCab listing for rear plates.

CNC-machined from solid-core virgin HDPE in Mount Juliet, Tennessee. Ford, F-150, Super Duty, SuperCrew, and SuperCab are registered trademarks of Ford Motor Company. Used for compatibility reference only.
