Absolute game changer for sound

I got a set of these for the front doors after I upgraded the factory speakers. I wasn’t sure what to expect from them since I’m just running off the stock head unit with no amp. The difference is bass output is absolutely amazing! What was a mild thump from the 6x9’s now sounds like I installed a small sub or amp. These plates are an absolute game changer! Installation is super easy and can be done in about 15 minutes per door. I’ll be ordering the plates for the rear doors soon. If you’re wanting to improve the bass and don’t want to or can’t install a sub then these will definitely make a huge improvement.

SOLID!

Take it from a guy who started making wood-based block-off plates as part of a high end install shop back in the 1990’s… these block-off plates will improve *ANY* speaker you put in your door. They close off the massive gaps that the manufacturer seals with flimsy clear plastic and makes something like an enclosure (or at least infinite baffle) possible with otherwise factory doors (meaning no pods).

I strongly suggest there be sound deadening material on the entire door, but at a bare minimum make a gasket with it to help seal the block-off plates.

Screws included are *greatly appreciated* and work well. I’m very impressed with the overall quality and thoughtfulness of this. HIGHLY RECOMMEND!

Door Panels

Not much to say, they're a good fit and easy to install. This is the second set I've done on my trucks.

Made a real difference!

These plates made my Focal K2’s come alive! Bass is very punchy and clean. Perfect compliment to the setup. Mosconi Pro 8/30 on the 3 way K2’s full active setup and K2 coaxials in the back. Fitment was superb and ALL hardware is included for mounting. Highly recommend these plates for serious sound improvement.

Installed these on my truck and they made a world of difference I have been doing my on stereo systems for over 20yrs even had some in competitions and this by far was an easier way to make door speaker sound better would definitely buy again

Awesome product. Very easy to install and fits great. Even the packaging looks top tier. I installed these and used sound deadening inside the door shells while I was replacing all the speakers in my 2022 F150. Drastically improved the sound over factory, the mid bass speakers have excursion now! If you’re replacing speakers and care about sound quality these are a must have. Thanks SG
