Hey all,
I'm looking to add a subwoofer to my 2011 F150 crewcab. I do not have the Sony audio or the factory subwoofer. I do have the 6-cd unit with the LCD display above the CD slot.

As best I can tell, there is an empty connector on the back of the radio that fits up with a WPT1212 connector. I would then just need to attach some RCA's to the WPT1212, and then use Forscan to enable the subwoofer output.

Looking at the Forscan spreadsheets that are out there, I'm not seeing anything for the ACM specifically for the 2011. There is a tab for the 13/14 and for the 12, but 11 isn't mention. That being said, the 2012 tab looks like the values I can see in my 2011.

Here's the current values for the ACM that seem to be relevant to enabling the subwoofer:
727-01-01 0704 908A A4F9
According to the spreadsheet, 4=E4SA default, DSP DTC E10100, AJ no aux jack, S2 default; and 9=S2V 4 volt, SV 2 volt, CRSD enabled, CFSD disabled
So I think I just need to change the 4 to a 6 and I'll have a subwoofer output?

I've attached a photo of the back of my radio, which shows the empty connector (between orange antenna and other connector) that I think I can use for the subwoofer. I've also attached a wiring diagram (bottom left connector) I found that I think shows the proper pins to use for a subwoofer.

Am I on the right track with all of this, or am I way off?

Just use an adapter that is plug in play to get your sub outs. I used one in my 2011 but that was 8 years ago. Maybe someone can chime in with the correct adapter model

I myself just bought the pac aoem frd24 to accomplish the same goal. I’ll be adding a 4 channel amp though. I’d check that out. It would be way easier.

Yep. That's the one!
