"Stealth V2" Focal Flax EVO Series 9-channel Fully Active Pre-Tuned Plug & Play Behind the Seat Stereo Upgrade for Select Ford 2023+ Super Duty Trucks with the B&O System

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.

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.

Purchased the Ford-specific Focal drops-ins from the outlet (well worth the outlet price) as well as the stealth behind the seat sub kit with full sound deadening and block offs. The install took a weekend because the door soundproofing is tedious (not at all hard), but the end result was VERY worth it. I may amp the Focals in the future, but they already sound quite a bit better than stock and the sound deadening / block off plates made a world of difference. The subs hit surprisingly hard for being 6.5" and they go fairly low for house, rap, etc. Country and rock have a great punch, although some rock music that has softer bass notes could use a bit more oomf... but it's a massive improvement over stock B&O system.

Had an issue with the sub box being damaged in shipping and although it's taken a while to get a new box shipped out, it was a no-hassle process. They are very good to work with.

I love it! It’s exactly what I wanted for my truck. I carry MX gear and dogs in my truck so anything other than this wouldn’t have worked. It hits hard but doesn’t alert people outside. My only wish was I would it sound better if I had just bought the whole kit instead of building my own? This was my first time building something like that.

the "Stealth" Behind the Seat Subwoofer Plug & Play System Upgrade (All Factory Systems including B&O Unleashed) has completely changed the sound and feeling inside of my raptor. I highly recommend this to anybody that feels like the factory system is under performing. This will blow you out of the water for what it is. Granite this is not a 10 inch or 12 inch subwoofer, but it is a massive upgrade to the OEM system.

I luckily got my Arealth 9 channel on sale for Black Friday. I watched the install videos on the YouTube several times and followed along step by step during the install which I did myself and didn't take to a stereo shop. Everything is clearly labeled and provided in the kit. A long as you can work an impact gun, razor blade, drill, and trim tool, it literally is 11 connections to make. I've never installed a stereo system before, but in two days, I had the very best system I've ever heard. Highly recommend these guys! I I did have to call in a few times for questions needing answered and they always answered them and walked me through.

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!

Sounds amazing! I have done many car stereo upgrades over the years and this one has been engineered to perfection. Install was very straight forward after watching the full install video twice. Four stars due to the ZEN interface. My backup and front warning sound is not as loud when music is playing and it is a bit delayed which is a problem when I pull into the garage. Also, a little disapointed that the package went on sale a week after I recieved it.

I was hesitant at first because I didn’t think a subwoofer upgrade would be too noticeable in my 2023 Raptor with the B&O system and would potentially muddy the sound but I was wrong. You don’t realize how underwhelming the factory system is until you get the SGS stealth kit. The subs hit hard and are extremely precise versus the overly bassy factory woofer.

Fit was amazing and the performance is exactly what I needed for the type of music I listen too.
