Custom Made Door Access Block Off Plates - Compatible with 2019-2021 GMC Sierra Chevrolet Silverado

I had received the front door plates as a gift from my wife. I liked them so much that I bought the rear ones as well. They really make my diamond audio speakers sound amazing in the stock locations. Excellent product.

These plates were very well made, great solid material and bolted right up to the inner door perfectly!

Installing my new system in my '21 Silverado CC and was recommended to get block-off plates. I have to say these are awesome and are a must when installing a system. Night and day difference with these installed!

These block off plates are top quality and look great. The versions that were sent to me have a cool design and logo, which you can't see on the ones online. I installed them myself (along with the noise deadening material), but took my truck in to the shop to do the wiring. The installer asked where I got them because he had never seen such a clean look and high quality block off plates. Definitely worth it!

Great quality, abs bends were needed to conform with door. Fully deaden front doors prior to Installing. Fit perfectly

Outstanding products and Customer Service!! Custom designed and made to fit. I ordered the Amplifier rack and Door Block off plates. Exactly what I needed to take my truck audio upgrade to the next level!! Thank you for making Great Products!!

I received these today and was extremely excited to see how well these worked. Upon initial unboxing all I could think was wow… these are really nice and very well made. All the install hardware is labeled and ready to go. There really is no install guide for these but if you need that you probably shouldn’t be attempting a high end stereo upgrade to begin with. I tried them first with the stock speakers and what a difference. Much tighter bass and a lot less “hollow” sounding. I then installed my Infinity Kappas all around 6x9 front 6.5 rear. I honestly don’t even think this was truck needs any subs. This sounds incredible. I don’t even have the AudioControl 4.800 installed yet. I may not even bother. Thanks Sounds Good Stereo for the fast shipping and amazing quality. Will definitely be a returning customer if they offer products for any future vehicle I own.

This product helps you complete a sound deadening door install with a touch of class.
Perfect fit block-off access plates help create a sealed enclosure for your door speakers, while leaving an access point should you ever need to replace a door window and/or regulator.
In my install, I chose not to use the screws that came with the plates when attaching them to the door. I used stainless steel 10-24 rivnuts and stainless steel oval head machine screws.
I had to widen the predrilled holes to accommodate this diameter screw. The result was a clean install without screws protruding the door panel.
I have enclosed a picture of my inside door panel. I am pleased with the way it turned out.
This is my first complete panel. I have three more to do.
