Great system from a great company

I purchased and installed the Focal flax evo 7-channel system in my F150 lightning. Wow, what a difference, the sound quality is amazing no matter what type of music I play! The system is really well designed and built. The quality of the setup and the workmanship are excellent. Installation was straightforward and a fun weekend project. The videos are very helpful and Sage and Don were also happy to talk through a few modifications over the phone. As I was installing the system, I realized one connecter was wrong. SGS immediately made me an adapter and had it express shipped to me overnight. That level of customer service really puts SGS in a class all by themselves. I highly recommend Sounds Good Stereo and this upgrade if you want great sound in your F150.

Game Changing

Not to pick on the other reviews, but I don't feel they give this system the accolades it deserves. Wow.... Wow. The change in sound quality is out of this world. The power, the bass, the mids and highs. All incredible. The other thing about this kit that is a very pleasant surprise is how much quieter the cabin of the truck is with the sound deadening. Huge difference. I highly recommend!!!

Top notch!! Amazing quality and sound

Love this setup. Came packaged up super nice. Everything was well protected when I opened the box. Videos made installation super easy. Took about 15 hours to install in my driveway. Love how it came out. System sounds amazing.

I recently purchased the “Stealth” Focal Flax EVO 7-channel Fully Active Pre-Tuned Plug & Play Stereo Upgrade, and I’m thoroughly impressed. The quality and attention to detail in the materials are evident, reflecting a genuine passion for sound engineering. Installation was a breeze - it truly was plug and play, making the process enjoyable and straightforward. The videos are super helpful. I encourage you to watch them at least 5 times while you wait ROFL!

The system’s performance is exceptional, with sound tuned to perfection, providing an immersive audio experience. The only caveat preventing a full 5-star rating is the logistics and somewhat opaque process of obtaining the product. Nonetheless, it’s a top-notch audio system that has transformed my listening experience. I would debate that it may be time for a branding change to Sounds GREAT stereo.

This business is highly recommended.

I can’t say enough about the product and the company. I had my doubts about the dual 6.5” and the amount of bass but SGS really did their homework with this setup!

Fantastic upgrade! 2020 F150 Lariat SuperCrew with B&O

I had this sub installed as part of a SoundsGood stealth package for my 2020 F150 SuperCrew with the factory B&O system. It system plays much louder and always clearer than the factory system This was exactly what I wanted.

The behind the seat sub is amazing. I knew it would be an improvement over the factory 8" sub, but it plays deeper and louder than I expected from two 6.5" drivers. They really did a great job with the design and construction of the sub.

I had the team at SoundsGood handle the installation. You can tell they take pride in their work with attention to detail that I have not observed elsewhere.

Since this is a stealth setup, there isn't much to see in the way of pics, but I will upload a couple of the setup behind the back seat.

I can't say enough about Don, Sage, Nathan, and the rest of the crew. Thanks for everything.

Gladen Stealth 7 channel active

I bought this system shortly after I bought my 2020 F250. which was around Feb 2023. I waited patiently and installed it upon arrival in about 2 full days and have been waiting to review it for a while. I have had systems in every car I owned pretty much, from basic cheap stuff to having K2's. These plug and play systems were appealing to me as they are tuned and ready to go but I still get to do the install which I like and helps me be able to trouble shoot it if need be. The listening experience was different for me as I tend to like a bit of a harsh tweeter and always had 10's or 12's for bass. It took a bit for me to get used to cranking the volume so high and having the listening experience so balanced. I am absolutely pleased with the sound of the system and the range it has for my musical taste. I listen to mostly SXM or Spotify and my taste goes from EDM to country to SXM Fly, SXM Turbo to Podcasts. No matter what am listening to I am pleased with the sound. The install vids they have online are amazing as well. I got mine on GovX which is greatly appreciated by the SGS team to provide that as an option.

Quality

Wow, my truck sounds so balanced. I will be upgrading the speakers later with their speaker kit to get more sound quality and volume. There is no hard part to installing this its just time-consuming but the sound material makes all the difference in the world. They have top-notch custom service. Tryst me it was worth the wait. Great sounding subwoofers. Thanks, guys

Focal Flax EVO 9-channel "stealth" system

Don and the family went above and beyond on the install in my 2022 Lariat.
Sage, Nathan, and "Barnie" spent hours getting a custom tune done for my hard rock ears and everything else sounds great as well.
Definately will be taking them another bottle of Kentucky bourbon the next time I'm down that way.
They care which is rare these days.
