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!

Sounds great

I bought this costume door block off plates, to improve the sound of the speakers and it did.
My surprise was, how solid the doors are closing.
Love it I'll recommend it.

Works well, not enough screws

Product seems to work well but I was 12 screws short

Fit great

Drill 1/8” holes and the screw right on. Fit was perfect. I also added sound mat and my doors have solid “thud” when you tap them and the speakers sound like they are connected to an actual stereo, not some transistor radio.

They shorted my two screws but I had similar ones on hand so no biggie. Overall, quality product, easy install and significant improvement in sound.

2021 F150 B&O unleashed

Extremely simple install if you follow their YouTube videos. Made a nice difference in mid bass on the factory speakers. They don't sound like they are in a tin can anymore. I also added sound deadening so I'm sure that helped, but it seems like the deeper and more pronounced "punch" from the speakers have to do with sealing off that big hole. Shipped in less than a week. Highly recommend.

2021 F150 B&O unleashed

Huge difference

These door block offs made a huge difference in the Mid bass and bass in my king ranch with the B&O unleashed system. Literally think the front doors now have more bass than the factory sub behind the back seats. (That will be the next item to get upgraded now) really impressive and quality/fit and finish is great. Only complaints I could even have were that my kit didn’t come with enough screws, but mid install I improvised, and including some kind of butyl tape or something to act as a gasket between these plates and the door skin would be a nice feature. I pulled the rubber goop off the plastic sheet and used that, but I know some users would just sound deaden the door first which would act as the same thing. Overall great product and it does what it says. Truck should have come with these.

Huge improvement to bass

I installed these on my 2022 GMC Sierra and made a huge difference in sound.

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)

Huge difference

Huge improvement to bass

Unreal sound!

Adding these focal flax 3 ways to my truck has made such an incredible difference in the audio quality of my truck. The range, tone, and clarity they add to the sound system makes this an absolute must!

Unreal sound in a complete package!

This is one unreal sounding package that includes it all! The quality increase from the factory B&O unleashed is massive. Perfectly crisp and bright highs, deep mellow mids, and a nice chest punch of base from the stealth box with one of the most eye appealing and neatly wired amp racks I have seen. Having everything neatly labeled with plug and play connections takes all of the guess work out of the install. The sound deadening and block off plates are a must and allows the system to play without interference. The focal flax speakers have a tone that is the perfect amount of warm and rich with a fantastic range. It's like getting to hear songs for the first time again with the tone and sounds that are now coming through with perfect clarity. The two 6.5" subs are nothing short of impressive for what they are. I'm amazed at the range they have, especially some of the deep lows and heavy Kicks's. This system plays every range of music to perfection whether you want the deep low thumps from rap, the quick chest pounding double bass from some metal, or the pure warm tones of a 70s guitar solo, this system keeps a smile on my face every time I turn it up.

Custom Made Door Access Block Off Plates

I purchased a set of door block-off plates to help seal my truck doors, and I couldn’t be happier with the product! The fit and finish are perfect, and the quality exceeded my expectations. Everything needed for installation was included, making the process smooth and hassle-free. Shipping was super fast, which was a great bonus. I appreciate the attention to detail, and it’s clear that this company takes pride in its products. I’ll be coming back for more audio gear! Highly recommended.

Custom-made-6-5-inch-front-speaker-adapters- FOR LEXUS IS class

Researching the needed exact information for the replacement of speakers for Mark Levenson equipped 2017 Lexus IS 350 F sport AWD was a somewhat tough job. Front speakers are 3.5" ML coaxial crap and most suppliers note 4" speakers as replacements. I opted for coaxial Hertz CX100 for the left and right fronts and Hertz DCX100.3 for the center-channel front. Brackets must be removed as the Lexus is 2 bracket mount. Modifying the plastic dash lip towards the windshield is required on left and right locations to allow these speakers to sit flat. I single smaller tweeter could be used in these locations with SGS adapters but you would lose a good deal of mid-range. The front doors have 7.1" dia. 5.3 Ohm which is near impossible to match with anything quality. The SGS 6.5" adapters work perfectly with my chosen Focal's. You can also separate the adapter and run the speaker wire adapters through a small slot that SGS provided. Plan for multiple hrs to attach sound-deadening material properly. The rear doors can easily be handled by readily available;e adapter for 6.5" speakers. I chose Focal PC 165 FE Flax EVO 6.5's for both the front and rear doors.
Now I wish SGS made an adapter to use a shallow 8" sub to replace the ML crap sub. No one lists a sub replacement for the 7.8" 6-ohm sub and the easiest way to replace would be to strip the plastic raised brace from the existing sub carefully to use a mount 8" quality sub-replacement. I am dreading starting the sub-replacement project. Thank you SGS for the front door adapters!!!!

Nothing is lining up

mounting holes don't line up with the tweeter cut out. wrong one sent?

Hey David, we sent you a email a few days ago regarding the tweeter adapters. In the email, we included mounting instructions from JL Audio on how to mount your tweeter into the adapter. Be sure to check your SPAM folder or reach out if you did not receive it.

1/0 Power & Ground cable 20 Silverado Trail Boss

Quality OFC 1/0 power & ground cable, with tech flex and fuse. This is a nice kit with the pre installed lugs and shrink tubing. Easy installation with a professional appearance.

Excellent product with room for improvement!

I just installed the amp rack you make for the Silverado crew cab. It fit but just barely and I had to cut 4 of the studs on the back wall off. It would be nice if the holes were countersunk so the studs underneath amps and other equipment could be utilized to make sure it's rattle free. Other than that maybe center the holes on the studs better. I'm sure making one from scratch would be quite the pain so all in all worth the $$$.

Perfect mounting of a custom speaker solution!

When installing speakers all over my expedition, I found certain speakers did not fit or accept the same size mounting even though they are advertised as the same "socket hole" -- 3 1/2 for instance. With SGS help I was able to overcome my front 2 corner speaker fitments and then with this product, I was able to fit my JL c7 3.5" center speaker with a PERFECT fit. I was so excited to see how well engineered the simple mount piece was -- and rigid! I was able to pop 4 screws and mount the speaker to the plastic piece SGS sent me and then put it into the center console space. It even aligned with the small helper pins to line it up with the factory screw holes and center the device perfectly as if it was OEM! I couldn't be more impressed! I am now looking at my rear mount speakers thinking I may pull the trigger again so I get everything just right. This needs to be advertised to those like me that a solution exists and it is not only affordable but well designed and executed! Thank you SGS one again fo
