Ford F-Series Truck Custom Behind the Seat Vented Subwoofer Enclosure Box

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!

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.

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

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.

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!

All I can say is Wow!!! I’ve had custom systems in all my vehicles for quite some time with 10’s and 12’s etc and I can Not believe how bass ass these 6.5’s are. I was super skeptical but I just gambled and went for it because of the custom fit. If you’re on the fence just do it. You will not be disappointed 👊🏻

Wonderful service by Don, he guided me trough the different options, and we landed my needs for my truck. Since I live in Norway, my trust to Don's advice was essential, and it sounds beyond! I went for the top package for sound treatment, which also did kill the road noise, and since I have a Lightning, its a new silent world, if I choose too. Sound good is super professional, from the details of how its packed, it came all the way over seas, without a dent. The installation is super simple, and with the videos in hand, it was smooth sailing. And the best, the installation was super fun! 10 out of 10, best money spent this year!

I installed the Ten87 Stealth subwoofer package in my 2024 F-150, and man, does it make a difference. Adds a whole new dimension to my factory B&O 8 speaker system. Excellent bass range; provides a balanced bass response and really kicks when you want it to. Highly recommended.

I was so excited to find these guys online, well worth the money and the wait. The system is everything I wanted in my truck and so clear and of the highest quality!! I’m looking at doing my Mustang next after watching their videos of another stealth system, thanks for this guys!!

Easy installation for me since I’ve done this in my younger days. Detailed videos help anyone to be capable!

Ordered mine in early February and they gave an ETA of mid April so it arrived today even a little early.

The attention to detail is really nice. Even the packaging was done really well. The enclosure fits perfect and sounds great. They don’t market this as an SPL enclosure but it definitely moves some air.

My only complaint, as it is with any behind rear seat enclosure, is the way the seat folds up now. It will fold up and latch but you really have to He-Man it into place. Not a huge deal since there is no forward facing woofer to damage. Not sure if there is something on the seat back I can trim. I will have to investigate.

I highly recommend.
