Behind The Seat Sub Enclosure

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.

Stealth Plus Behind the Seat Package

Had this system installed by the guys at Sounds Good Stereo. Best money I have spent so far on my truck. Bass is incredible, the sound damping is incredible. 10 out 10, highly recommend. Looking forward to having the guys upgrade the rest of my system.

Good quality…

Turnaround time was a little long. It was made a lot longer being my first order was “lost in the mail”. Not the fault of Sounds Good Stereo. Installation took some time. I did not receive any sound-deadening in my package, so I modified the existing material to work with the new enclosure. It's a little tight but I made it work. The video helps with installation but could of help with running power and ground to the battery, that part was cut out. Overall good quality, detailed instructional video., and even better than what I was expecting. The sound is night and day which is what mattered the most.

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.
