Subwoofer behind the seat

A1 product, sweet sweet subwoofer, engineered for fidelity. Well packed and all tools, cable and template include (sub switch). Just one thing that should be included as well is the sound deadening that goes behind the subwoofer.

Stealth behind seat sub package is the kit to buy

Received this kit a month ago and finally found the time to install it in my 2022 F150 Supercrew with the B&O Unleashed system. This kit has made a world of difference for me.

I initially installed the door blockers and used cheaper sound deadening material for my doors and ran that for a month before installing this. That kit also made a noticeable difference. But the bass can now really be felt, which is impressive for a dual 6.5” box. And it isn’t even broken in yet.

Install took me about 5.5 hours. And this is with tracking the install video. Having an impact drill saves a lot of time. So if you have one, use it. All of the parts and accessories are top quality. I imagine a lot of engineering and thought went into the design and build of everything. I had a few questions within the hour before SGS closed and they answered my calls and took the time to walk me through my questions. Great customer service guys.

I couldn’t be happier with SGS and this product. It took some time to install everything myself but I believe I got a superior end result to what my local shop would have charged me (yes it includes install costs) over $800 more for. And the install work was not hard.

Nice Fit, Nice Sound

The stealth subwoofer enclosure, subs and amp were installed in my 2023 F-150 yesterday. Took a good part of the day, but the finished product sounds great. The installation video was very helpful. I called the guys with a couple questions, and they answered the phone and were very helpful. Really happy with this purchase. Yes, I would recommend this product.

2022 F350 Lariat - Stealth Sub Package

I purchased the stealth sub package. I have not upgraded anything else for the stereo system, but this upgrade is something beyond words. All I can say is wow!!! It's night and day. Very high quality kit, very well packaged. True plug and play and these 6.5s are a huge upgrade from the meager B&O sub. I also called in for a few questions and SGS team was super helpful. I think I may have to spring for upgrading my door speakers next. Thanks for this awesome product totally worth the wait. A++

Stealth Box and Amp Kit

I purchased the behind the seat sub box and amplifier kit. Installation was a breeze following the youtube instructional videos. Ran the power and ground wires underneath the truck (per videos). The rest was plug and play. Those subs added to the B&O system has my truck sounding great! The two 6.5" subs hit pretty hard. Although they are not 10s or 15s, they work very well! Mad shout out to the SGS staff for being very professional and helpful! The lead time of 8-12 weeks is well worth the wait!

Stealth Box

Overall very satisfied, the box sounds great for being two 6.5's. It hit's crazy lows. The fit is very tight. It took a bit to get in but once it's there it's there. Amp rack also was a great fit. I do wish the amp box was shipped with it's contents. (directions/extra cables) I'm going to say worth the money.

Performance of 6.5" Subs

How much deep base do these subs actually push? Is there a single sub solution that has better performance?

Great low bass if fed the proper signal, wattage and tuning. At the current time, no single subwoofer will fit + outperform this. As subwoofer technology expands, we will look into other options. The reason this enclosure works so well is the benefits of a vented design over a sealed one.
