2015-2020 F150 & Super Duty Kicker VSS Substage Powered Subwoofer Kit

Highlights:
Fuller, Deeper Bass
Easy, Drop-In Installation
200W Amplifier
SuperCrew and SuperCab Only
Increased Bass Volume and Depth in an Easily-Installed Package
Ford's F150 and Super Duty trucks need some bass. There's absolutely no doubt about it. Even the trucks with the premium Sony Audio package are a bit lacking in a powerful bass note, but our friends over a Kicker Audio are here to help with their Vehicle Specific Solution (VSS) Substage Kit. This kit is a full enclosure that comes with a large 8" Kicker Subwoofer powered by its own 200-watt Kicker amplifier that gives your pickup more bass and more depth and makes for an absolutely huge sound quality improvement on the 2015-2019 F150s and 2017-2019 Super Dutys with base audio. The kit is designed to bolt into your truck where the Sony amplifier would've been installed, and use existing bolt holes in the floor of your truck under its rear bench so that you don't need to come up with a custom mounting solution in order to get an excellent sound quality upgrade for your F150.
Features an 8" Kicker Subwoofer and Kicker 200-Watt Amp in a Full Enclosure Assembly
The Kicker VSS SubStage System is built around an impressive Kicker Subwoofer that generates a louder, deeper bass note than the Sony 8" subwoofer while giving your entire audio system more range and depth. The Kicker Subwoofer comes preinstalled in Kicker's complete enclosure assembly and pulls power from Kicker's 200-watt amplifier that solely powers the Subwoofer and is likewise already installed in the drop-in enclosure. Each Substage System comes with a full set of wiring that allows you to easily run power out to your truck's battery and tap a source for the subwoofer with minimal amounts of wiring work. The Substage kit comes with a full set of high-quality instructions for both the enclosure installation and wiring.
SuperCrew & SuperCab Only: This system will only fit 2015-2020 F150s, 2017-2019 Raptors, or 2017-2019 Super Dutys with a SuperCrew cab (Crew Cab) or SuperCab (Extended Cab).
F150s with Auto Start/Stop: F150s with the stock Auto Start/Stop systems enabled may experience the Kicker System cutting out temporarily when the truck switches from its alternator power to its battery power. Unfortunately, the only known fix is disabling the Auto Start/Stop feature manually or permanently via custom tuning.

I hate to be the "will this fit?" guy, but I am genuinely interested in it if it will work in a 2019 Supercrew XL w/ the STX package. It seems I recall something about checking behind the rear cab panel to see if there was a connector there.

 

Should fit

 

I have no idea, but I think you are right concerning the connector. This is from the literature (and in my post)
