Updated with Wiring Diagram
UPDATE:
Finally installed my JBL GT 10" sub and JBL GTO 501 ! I used a Scosche LOC2SL line out convertor connecting to the subwoofer out on the ML amp. Although I wish I ended up getting a more quality LOC like AudioControl's LC2, the Scosche seems to do the job just fine.
I attached the wiring diagram for the Mark Levinson 17 Speaker Amplifier, same ML Amp found in the 4th Gen GS.
Subwoofer (+) is the #21 Blue Wire on the T40 Plug
Subwoofer (-) is the #6 White/gray Wire on the T40 Plug
ACC (Remote Turn-on) is the #8 White Wire on the T49 Plug

Yeah. How does it sound. I have 2 12s from my 3Gis that I have been staring at. I'd like to know if it's worth putting in. Yet, I have the lc2i and remote bass ****. The option to turn the sub down was the only way I wanted to do it since some passengers are too sensitive

Happy to see that other owners are underwhelmed with the sound quality of the "extra $pecial" Mark Levinson system in this car. I expected the separation to be poor (small space), I expected the sound to be thin (small speakers), but I didn't expect how poorly the system compensates for road noise. I don't know if an active sound canceling system would be helpful, though.

Well, my wife's old 2008 ES 350 with OEM (not ML) system was better to my ear. Probably because the cabin itself was much better insulated against road noise. My current Lincoln Revel system (19 speakers and active noise cancelation) is far and away superior to any system I've had previously (including home theater sound system in my house). I had bose in a couple mercedes and they were pretty good and (IMO) better than the sound in the RC. I think it is more of the sound "field" is so tiny in the RC cabin, but more annoying is the road noise compensation is poor. I should not have to increase volume manually just because I driving over a less than perfect road. I "get it" that it is a sporty car and more folks want to hear the engine, but I don't think many folks want to hear the tires.

I'd love to see some pics of the woofer placement if you have it.
