Block off Plates

Sound good sells only the best products. These block off plates look very high quality but have not been installed yet.

Outstanding Product!

Installation isn’t complicated, but it would be nice to have some reference points as to exactly where they are be positioned. They cover the main openings as well as smaller ones nearby to completely seal the door panel, but getting the orientation just right before drilling holes for the screws is a little tricky. I would drill two holes while holding the piece in place and then put the two screws in to locate it before drilling and adding the remaining screws. Was going to add component speakers to the front doors, but decided to hold off and I’m glad I did. These plates and some sound deadener completely corrected the lack of bass from the factory Bose speakers. I also added some thin material to better seal these to the doors. I couldn’t feel the bass at all from any of the door speakers prior to adding the panels, but that isn’t the case anymore. Extremely pleased with my purchase!

Perfect fit!

These block off plates were perfect for my 2024 Silverado HD! Complemented the sound treatment and added a lot of control and depth to the midbass! I wouldn’t consider a speaker upgrade without using these panels or you’ll leave a lot of sound potential on the table!

Exceeded My Expectations

These front door block off plates were exactly what I wanted and needed. Anyone with a Tundra knows that it’s difficult to get good mid bass from Tundra doors.. This was the final piece I needed to get my mids where I wanted them. I only ordered the front plates just to make sure they were what I needed. They exceeded my expectations and will be ordering them for my rear doors now.

Good product. Very stiff and adds a lot of rigidity to the door and covers the big holes well.

Took a little while to ship, a couple of weeks or so, but worth waiting for.

The kit I got included 3 panels for each front door, but it only included 2. I think the non-used panel would be for it to fit a 19-21 model but I'm not sure.

The 22+/refresh (24+ in HD trucks) have a foam block on the door panel that extends through the door skin. I did find that the hole cut in these block off plates didn't line up correctly for that foam to fit. Maybe you're supposed to trim the foam. I trimmed the plate about 3/4" off of the bottom of the cutout. There were no install instructions included that specified.

I used a strip of melamine foam between the panels & the door skin to decouple & seal it. Something else would probably work better, like CCF, but it's what I had.

Plenty of screws included and the screw holes are placed well so that no window regulators or wiring is hit on the inside of the door skin.

I will definitely purchase these for my next system as well.

Product required modifications for a 2014 F150 Platinum. Had to drill holes for additional wire harness. Only hole is for the door handle cable. Also had to drill holes for additional wire harness mounting clips since block off plate covers the original holes.

Are you looking to build the ultimate enclosure in your door panel? If so, these block-off access plates will improve your mid-bass performance and deliver the sound you're looking for.

- Hand-made here at our facility just outside of Nashville, TN
