Can’t speak for all 6.5” speakers, but my Focal KX2 mid bass drivers and Flax Evo coaxials fit like a glove. Absolute necessity when upgrading speakers.

My 2024 Raptor was lacking in sound, but I also didn't want to give up the storage compartment under my seat since I actually use my truck for truck things. After A LOT of research and a few estimates from local stereo experts that cost an arm and a leg, I found SGS on a couple forums with a solution that fit behind the seat.

I purchased the V2 stealth behind the seat option that has the two 6.5" subs and sound treatment. I put this together over the course of 3 days to hear the differences in sound.

Day one: Installed the behind the seat subs with sound treatment and block off, very easy process. The subs cleaned up the muddy bass the factory sub provided. For my preference I maxed out the provided controller and turned the bass down on the factory EQ. While the bass was now sorted, the rest of the sound wasn't.

Day two: Installed sound treatment on both front doors with block off plates. To my surprise this REALLY cleaned up the stock mids and highs. So much so that I had to adjust my EQ from just doing the front speakers.

Day three: Installed sound treatment on both rear doors with block off plates. This completed the sound for me. I had no idea the factory system could sound this good. This sounds just as good as my Audi S6 that has the B&O upgraded system.. but it turns up higher, has more bass, and sounds cleaner!! The air noise I usually hear in the truck has been reduced quite a bit now and the doors shut with a premium sound (I know that sounds weird). I also have no rattling at all now, no matter the bass level.

No more tinny sound and all of the small nuances in music can now be clearly noticed when before it just sounded like garbage through a tin can. The bass is clear and punchy. Since I listen to all sorts of music and genres, I put the truck to the test for a couple hours in my driveway, smiling the entire time. From rap to rock, the 6.5" subs sound awesome! You can max this out to 30 on the factory head unit and it still sounds clean! This system doesn't skip a beat. Anyone looking for a solution that keeps the stock speakers and head unit, this is it!! Now you won't hear this thing pounding from down the street but it's plenty loud in the truck.

Don't cheap out, get the V2 that has the sound treatment. It'll be 100% worth the extra money spent. I'm extremely happy with this upgrade and can no finally drive my truck for hours while listening to quality music. Thanks, SGS!! Please make some stuff for cars so I can upgrade mine!

I bought the 7 ch active system for my 23 Raptor, after soon realizing that the factory B&O Unleashed system was lacking in volume, bass, and sound quality. While researching upgrades, the forum reviews all seemed to lead to the same place - Sounds Good Stereo - as they had fully embraced Ford F-Series trucks. The system arrived exactly 12 weeks after my order. When you see all the work they put in, you’ll understand why the wait is necessary. The system was well-packed to protect the components. It took two and a half days for me to complete the installation, with the sound treatment taking the greatest amount of time. It truly is plug and play. I highly recommend watching the install videos before you begin. It absolutely brings music to life! You won’t believe the difference in sound quality, volume, and bass. One friend said it was the best system they had ever heard in a car or home…and I could only agree!. You’ll hear notes in the music that you didn’t know existed. The sound is very well-rounded with crisp highs and a deep bottom end. The subwoofer box fits nicely behind the rear seat and really bumps. I did not lose any functionality of the rear seat, but did have to relocate the jack. I primarily use Spotify as the source and listen mostly to Rock, but the system performs well with any type of music. Thank you Sounds Good Stereo for doing the research and creating systems of such quality. My recommendation…just buy it!

Phenomenal sound. I was amazed at the power of the small subs. Enough bass to bring out the lows when it’s dialed down; and hits hard enough to make you grin like a teenager when you dial it up. Debated building my own custom box… don’t do it. This fits with precision and is custom tuned for the application. The quality you pay for and expect is exactly what you get. Only complaint would be that I received a surface mount remote bass knob, but was expecting a rear mount. Had to get creative to find a lower ledge to mount on, whereas there are plenty of blanks where a rear mount would work. Turns out I like it where it is, so no real complaint.

The Amp Rack kit arrived and was packaged very securely. The board itself is wired very neatly with pigtails for plugging into the sub and factory amp..

All of the accessories (heat shrink/flush cutters/zip ties/mounting brackets/hardware) were bagged and labeled. The installation, after watching their youtube videos was exactly as described and truly Plug and Play.

I could not be more pleased with this kit, and would highly recommend it to anyone!

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!

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.

Installed the Stealth V2 enclosure in a 2024 F-150 Lariat (14 Speaker B&O). The enclosure fits perfectly behind the rear seat. Note: the two bolts that secure the OEM Sub Enclosure must be removed in order for the Stealth V2 to fit properly. I’m very pleased and impressed with the two 6.5 inch subwoofers! I have the Musway 5 channel (Five.100+) at 1x400w @ 2 ohms driving the Stealth V2, and driving the front and rear speakers at 4x115w @ 4 ohms. In my opinion, this is the perfect option for a very nice bass upgrade, while maintaining the storage space under the rear seat. Great design, and great customer service from the SGS Team!

Love the kit, was easy to install in a 2015 Supercrew. The videos helped a ton to watch before starting the project to get prepared before starting. I started out trying to build my own system but realized how much I didn't know about car audio and this was the perfect solution down to the tools that came with it. My only suggestion is to include a roller with the sound deadening, that was the one thing I forgot to buy ahead of the kit arriving. The $3 one from ebay worked great.

This custom box is a fine piece. The quality of the build is exceptional and the finish with the leather wrapping and corners and the custom logo plate looks and feels much better than I expected. All the materials are the finest quality with precision, craftsmanship, and intentional design from start to finish. And the sound of the box is even better. I have the 3-10w3s and they don’t disappoint in sound quality and punch with a deep low end and plenty of output for all my variety of listening. I’m so glad I made this decision to get this box. The price is intimidating but that value is 100% there. Don was also amazing with advise and staying in touch through the build. Thanks so much yall.

I just received the amp rack today and I must say this is one of the nicest made amp racks I have seen, very heavy duty and sturdy rack. The finish on it is perfect for any build, gives a nice clean looking install

Excellent product and company to do business with. The quality of build and products are second to none. I would not hesitate to recommend or do business with them!

These hand-crafted custom A-pillars are of significantly higher quality than the OEM parts. When paired with SoundGoodStereos’ expertise, they completely elevated my sound system to another level. The precision and craftsmanship are top-notch, and they perfectly complement the audio setup in my 2023 F-150 Lightning. Highly recommended for anyone looking to enhance both the look and performance of their truck’s audio system.

I was skeptical about how good this enclosure would sound, especially with 6.5" subs. My product was delivered as expected. The subs installed were soundqubed. I pieced this install together with the Kicker 5oo.1 for the subs and the Kicker 200.4 for the Morel mids and highs. I'm very picky about sound quality and this setup met my expectations. The bass is nice and clear. Will this make the the reflection in your rear view mirror blurry, yes it will. Will you hear it from down the street, no. It makes for a well balanced quality sound system.

I recently installed the plates on the front doors and was amazed at how much of an improvement to the bass output they made. So I got the set for the rear doors as well. I didn’t think they would make as much of an improvement as the front doors since the rear speakers are so much smaller. Boy was I wrong. Tge rear plates were not only as easy to install but made as well of an improvement in bass as the front plates. The bass fills the cab now and there’s almost no need to add a sub to the stock system. Just upgrade your speakers and add these plates and you’ll be set. The plates are perfectly aligned to the doors and installed in minutes. Worth every penny too. I never would have thought that these plates would have made such a difference in bass response on a factory non-BMO system. I compared the mine to the Unleashed version and the bass is so much better in my non BMO .
