Product Description

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.

Bought this t harness for my 2026 Chevy ZR2,

Bought this t harness for my 2026 Chevy Silverado ZR2, worked perfectly for my kicker HS12. So easy to install, plug and play.

to create the best sound as I can

Im not an audiophile but I want to create the best sound as possible and was told that these would help. I recieved the order in a timely fashion, and got to work on the project. Straight-foward install and made a noticeable difference in the sound from the doors.

Bought the Blackhole tiles to sound deaden

Bought the Blackhole tiles to sound deaden the doors on my new F150. Not only did they quiet the ride but the stereo sounds much better. Where i was hardly getting any volume out of the door speakers they now sound much improved. When paired with the block off plates Im now much more satisfied with the sound.

Amazingly simple!

The plug-in play harness with the preconfigured key-loc is wicked. Takes all the guesswork out of the calibration plus, NOT having to cut the factory wiring is worth every penny.

The kit was so easy to install and it makes the factory stereo sounds so good without the bass roll off.

Amazing quality on that harness!

Best LOC

I've tried Audio Control LC2i Pro, the Audio Control Epicenter Micro, and the built in high level inputs from JL RD500/1. I'm now using this product along with the RD500/1 amplifier and it has never sounded better. Glad to have purchased this!

Used the adapters to swap to JL Audio C6

Used the adapters to put JL Audio 6.5” C6 speakers in the kick panels of my 2026 Ford Bronco Base 2-door. The wire passage holes needed to be drilled out larger and passenger-side adapter needed slight clearance adjustment with a dremel to fit under a steel bracket under the dash. No big deal. Material is easy to drill through and grind. Otherwise, these adapters work perfect for swapping out the Bronco kick panel speakers.

Great product, fast shipping and good customer

Great product, fast shipping and good customer service. Highly recommend

Fitment was amazing

Fitment was amazing. Shipping was quick. We do car audio every day and this is a huge time saver for us!

C6 door blockers

They were really easy to install and look clean and work perfectly

Just buy them!

I ordered these along with the jl audio c1 kit for the front and rear. I only wanted to take the door panels off once so I went ahead and bought these block off plates..they essentially turn your door into an enclosed speaker box and gives you more bass. Also makes your doors feel more solid. Glad I purchased and installed these, I feel they bring out the best of the jl audio c1 kit!
