"Stealth" Behind the Seat Subwoofer Plug & Play System Upgrade (All Factory Systems including B&O Unleashed)

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.

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.

I bought this stealth kit for my 2022 F150 along with their block off plates, and sound deadening. I had already upgraded my door speakers so I also added another amp from them for the door speakers and Zen interface. I had some issues early on with a harness they supplied but they were quick to respond and ship me a replacement to fix the issue. My only complaint is the pre wired loaded amps are upside down. Maybe by design? But it sure makes it hard to adjust the gains when the rack is bolted to the truck. I’m still tweaking the settings, but this setup gets LOUD! Way better than the stock Ford stuff. The video install they have helped a ton for a do it yourself install. One thing I noticed is the carpet was very close to the subs, so I ended up cutting my carpet out on the floor where the two subs fire down. I also cut the stud down that they tell you to be very careful not to put thru the speaker. For me I’d rather just eliminate that possibility. I definitely will not hesitate to recommend this setup from Sound Good Stereo! It is a very nice complete set!

Installed the Stealth" Mosconi-Gladen Audio RS 5-channel Passive Pre-Tuned Plug & Play Behind the Seat Stereo Upgrade on my 2021 F150 and first off it sounds absolutely amazing. The small subwoofers pound SIGNIFICANTLY harder than the OEM Ford/Kicker unit I installed when I first got the truck.

Only reason I gave it 4 stars is the driver side seat no longer locks in the full upward position, which can be frustrating when loading larger items on the floor.

I ordered the Flax active plug and play system for my ‘22 raptor. Took a little while to build but the kit that arrived was all inclusive and completely plug and play for anyone who’s even a little bit comfortable turning a wrench. I made a stupid assembly error and Sage was very helpful and patient with troubleshooting for me remotely. The sound quality and power is awesome.

SG has this Dialed in Yall!!!! It Transformed Sound in my 23 F250 AND Kept all my storage under the seat. I'm amazed at the balanced clean sound they've Perfected! All i can say is Just Do It!!!! You Won't be disappointed! They're a Pleasure to do business with!

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 would like to say it is well worth the money!!! Sounds so Good!

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.

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.
