Easy and awesome upgrade!

Installed the front and rear block off plates along with some sound deadening. Installation was fairly easy, just make sure you use the alignment holes for the front doors so the door panel aligns with the recessed portion of the plate.

After the install, I noticed a significant reduction in the muddiness of my speakers. All in all, this upgrade is well worth it!

F150 block-off plates

Well made product. Perfect fit on my 2023 F150 regular cab. Easy install, even extra screws included.. Highly recommend.

Awesome

Changed the sound of the stock door speakers ... for the better. Can't wait to move on to step two and change out speakers and add amp.

Wonderful sound

After installing a Kicker Key 200.4 amp (using a SGS harness) I opted to add their block off plates to all four doors. Installation was straight forward but I would recommend a second pair of hands when you drilling of the first couple of screw holes to hold the plate in place. The fit was right on and I have experiences no rattles. I used some weather striping foam as a seal between the plates and the door metal. I also installed some sound deadening mat. The hardest part was figuring out how to release the door latch cable.

Perfect fit and absolutely necessary imo!

Fit as they should and are very well made. These along with the sound treatment make the doors a much more friendly environment for your speakers.

Very happy with purchase

After DIYing multiple sets of block off plates I finally decided to spend the money on these. Glad I did as the fit was perfect and install was a breeze.im very happy with my purchase.

Impressive sound enhancement

I ordered these block off plates as a first step to upgrading the factory Bose system in my 2021 Denali HD truck. The difference these made on the stock speakers was extremely impressive. Honestly how the stock stereo should have sounded. The only reason I did not give these 5 stars is the fitment wasn’t very good. The covers did cover the large access holes in the doors but didn’t seem to line up very well with the same proportions as factory. Overall worth the money and the upgrade for sure

Works Great!!! Love these plates!

These worked great on a 2024 F-150 Regular Cab, they seem really solid. Can't beat it for the price. Thanks again Sage.

Perfect fit, superb product.

All the products I purchased were absolutely perfect in terms of fit and function. I bought these and some speaker adaptors for my Morel 8" drivers. I am a fan of this company. Thanks!

These are awesome would buy again!

Product Description

Our best-selling 2015-2020 F-150 item is now available for the 2021+ Ford F-150. If you know what these are, then you know how much better they make your stereo system sound.

If you have no idea what you are looking at, it's a custom-made plate that blocks the factory vapor paper hole and improves your mid-bass substantially, without changing the speakers. So if you are tired of the muddy, boomy lower mid-bass of your F-150, here is the most cost-effective solution for you.

These are made in-house from High-Density Poly Ethylene (HDPE) which is a great stable product for the vehicle environment and much better than your PVC or ABS plates due to their non-porous and density properties.

Just use the alignment holes at the top of the plate, pre-drill holes, apply weather stripping or sound treatment to the metal, and mount the plates. These are complex to build due to the factory door panel protruding into the door, so we designed a multi-piece plate to ensure perfect factory fitment when the door is re-installed.

- Hand-made here at our facility just outside of Nashville, TN
- Multi-piece front plate design
- Available for the front doors & rear doors
- Use sound treatment to ensure the best seal
- Made of high-quality High-Density Poly Ethylene (HDPE)

Plug and play

I purchased this harness and the infinite baffle block off plate together for my 2025 F350. Both were super high quality and saved me the time of figuring out what connectors I need and what wires needed spliced to get the feed to my kicker key500.1 amp.

I had a couple other questions and when I called the SGS guys they were super friendly, helpful and knowledgeable on the phone.

Worth every penny. Got me up and running in no time. I paired this with a pair of Rockford shallow 8's behind the seat and the performance is incomparable vs the factory "subwoofer".

Will absolutely go straight to SGS for any future needs.

perfect harness - if close by

The harness is exactly what was needed to tap into factory signal for after market amp. Only problem I ran into is my new amp is mounted 2-3 feet away from the factory amp and this harness is pretty short, so I had to go searching on amazon for the 4-pin extensions, which I could only find in 8" segments (made of computer uses). Definitely would be nice if SGS sold some extensions that could be purchased along with the harness so buyers could be sure they're getting the right products and they're all arriving together. But that said, their harness makes life easy, and shipping was fast! Plug and (wait for extensions and...) play! ;)

Well worth the money. Long wait.

I wish they listed the time frame that it will take to complete your order. I had no updates until I decided to message them 2 weeks after I ordered and was told it would take about 2 weeks since the brackets had to be custom made. It ended up being delayed until almost a month before my product was shipped. That was my only gripe. The product was great and packaged well. I would've gladly waited a month so as long I was made aware of the wait instead of sitting around wondering and having to follow up with them multiple times.

Real nice unit

Ordered mine in early February and they gave an ETA of mid April so it arrived today even a little early.

The attention to detail is really nice. Even the packaging was done really well. The enclosure fits perfect and sounds great. They don’t market this as an SPL enclosure but it definitely moves some air.

My only complaint, as it is with any behind rear seat enclosure, is the way the seat folds up now. It will fold up and latch but you really have to He-Man it into place. Not a huge deal since there is no forward facing woofer to damage. Not sure if there is something on the seat back I can trim. I will have to investigate.

I highly recommend.

A+++++++++

I purchased an amp rack for my raptor. Price was great and shipping was super fast. The quality of the rack is top notch and fit perfect. I called them a few days later to ask a few questions and they went above and beyond to help and it had nothing to do with the rack. These guys are awesome 👏🏿 👍🏿✌🏿

Best Amp Rack you will get!

Title says it all!
Everything Sound Good Stereo does is all about top-tier craftsmanship and unmatched quality. Their attention to detail and dedication to excellence truly sets them apart.

F150 Arc Audio Sub Enclosure! Feel like a kid again!

The quality and craftsmanship are outstanding. The bass hits with serious power! This thing weighs in at around 90 lbs. Love the LED lights! Feel like a kid again!

F150 Arc Audio A-Pillars

The quality of work is truly exceptional. I couldn't be more thrilled with the custom A-pillars. They look like they’ve always been part of the truck. I've received numerous compliments already. It was a huge upgrade for the front stage audio. You can't go wrong choosing Sound Good Stereo to create A-pillars for your F150.
