CNC-machined HDPE block off plates designed to seal the factory speaker access holes in your 2018-2023 Ford Expedition or Expedition Max 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 and secure with the included zinc coated screws. About 2 hours for all four doors.

Fits both standard Expedition and Expedition Max. All trim levels and audio packages.

CNC-machined from solid-core virgin HDPE in Mount Juliet, Tennessee. Ford and Expedition are registered trademarks of Ford Motor Company. Used for compatibility reference only.
