I did it myself with forscan. I would suggest doing it yourself, as there a few choices in there that can make it sound quite bad. My truck has the 7 speaker system with the 4.3 display, sync and Sirius.

The first time I tried, I chose the "kicker" option and it sounded terrible with the Alpine powered sub I set up. I had to go back and chose the 7 speaker+subwoofer (not kicker) to make it sound proper. The kicker option obviously added some signal processing to the outputs that work fine if you have the full kicker system, but just adding the subwoofer required a different setting. I wouldn't trust them to get it right the first time.

On the Plain English Page in the ACM, the top line needs to be changed also. The top line should be written as "Auxilliary sub woofer" in addition to enabling the correct model of truck (supercab or supercrew & 6 or 7 speaker system). Make sure this is done and you can do it yourself quite easily. Save the original or As-Built file for the module you are working on as soon as it loads and you can always return to stock without issue.

Does this simply enable an un-attenuated low level output from the head unit as if there was an output on it for RCA cables?

Baaaaaaaaaaa

I'm interested in it as a way to pull signal for my JL audio amp and sub. So it sends me a low level signal, or a high level, or do we know? No idea if the factory amp was designed for low level input or speaker level inputs. I would imagine traditional low level but you never know. I'd prefer it be full range, so I can power door speakers also. So maybe this isn't for me.

I know it applies to 13th gens. '16+. I'm not sure about previous.

Thank you much. If it's summing the left and right for mono then it's really only good for a sub, not much use for me. However, it sounds like there will be benefit by going in there and switching over from the kicker settings still. My door speaker upgrades will require an amp to run. I was hoping this was my ticket to finding a nice clean low level input to bypass the need for a DSP. My amp will accept high level inputs, but I really don't wanna do it that way.
