Perfect upgrade to the B&O Unleashed system 2023 Ford Raptor

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.

Plug & Play

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.

2024 F-150 Lariat Stealth V2 Bass Upgrade

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!

Nice upgrade over factory B&O

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.

The perfect bass upgrade!

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.

Sounds Awesome

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.

Amazing Sound Great Service!

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!

Amazing sound, minimal loss in function

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.

High quality product, responsive service.

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.
