Exceeds expectations Surprised my pro tuner

I took my F150 to pro tuner after finishing my install, 9 channel DSP. The guy went on and on about the sub performance during the tune he set the crossover at 25 Hz. Today I got a follow up message from him.
“it’s honestly a great setup you have. I’m very surprised by how low the subs play as well, plus it doesn’t take up any space at all”

High quality all the way and sounds amazing

You can tell this is a quality product the moment you open the box. Extremely well packaged with items clearly labeled. If you have even the slightest technical ability this system can be installed in a few hours. No physical instructions are included but you can find what you need on the website or via YouTube. Once the system is in, it sounds amazing. I was a little concerned how it would sound, but I couldn’t be more impressed.

2024 F150 B&O 8 speaker

I Upgraded my 2019 F150 w/ JL audio stealth box to a 2024 f150 and the standard B&O 8 speaker just does not have enough sub.
So I picked up the Stealth v2" Behind the Seat Subwoofer Plug & Play System Upgrade & I love it. I will definitely recommend if you’re looking for a stealth box. No one will know you have subs until you want them too.
one suggestion to the sound good team the 2024 f150 back wall is different than your must recent video. so your install video needs updated for new location of the amp, the power & the sub controller. But The team was awesome I called with a few questions and they walked me right through it.

Other than it’s a super easy install , true plug in play and they provide everything but the sockets .
Thank you sound good stereo team .

Can’t imagine believe it

I bought the sub and amp rack last year. Ran it for awhile and then decided I needed to upgrade to DSP. I had doubt about the size of the subs . It had great base with the Key amp but now I put an Audison mono amp 1000 watt at 1 ohm, turned down gain to match sub. And wow. I had to go to empty parking lot to listen to some EDM.

Awesome product backed up by even better customer service. When choosing a new amp I called and a real person answered! He took the time to look up some amps and gave me suggestions. Thank you!!

A must have

This is how the B&O Unleashed bass should have been setup from the factory. If you’re on the fence just do it, you won’t regret it.

"Stealth v2" Behind the Seat Subwoofer Plug & Play System

this is an amazing add to the B&O Unleashed system on my 2025 F250. Wow.... Sounds like you have two 10" subs under the seat and extremely crisp! You have to hear to believe. Very happy!

You need this

2024-F-150 B&O 8 speaker. I bought the stealth box, kicker keyloc with harness for roll off correction, rear door and rear wall block-off plate, and two rear JL audio speakers for the rear doors. I added one 5 channel amplifier to power the stealth box and 2 rear JL Audio door speakers. It was easy to reroute the two rear door speakers in the provided harness to the amp and back in the other side. Basically, front speakers are still B&O and the rear is Sounds Good Stereo. I'm really happy with it.

Amazing Sound

I enjoy the EXTRA base. It is tuned correctly and works great with the Ford stereo. The product is definitely as described.

Words can not describ!!!!!!

I am very impressed with the quality and performance that these 2 6.5 subs sound like. You can't go wrong with this purchase. It plays all the lows very well and sounds like a big system. No distortion no clipping at full vol. I was also impressed with the install. Very easy!!! The detail they put into this system is over the top. You won't be let down.

Worth it!!!!

I was debating on a route to go for adding more bass to my 2020 f350 platinum, and my biggest issue was I didn’t want to lose under seat storage. After much research I found sounds good, and decided to order the behind the seat kit and was just hoping the 2 6.5” subs would preform to my expectations. I ordered it and received it within the time frame expected from something custom made. Overall install was super easy I did it in one afternoon and all being plug and play was a game changer!
Super happy with the decision i made and ordering from sounds good, if I ever have to order for a different truck it will definitely be from them again!
