Hey fellas! Anyone on here added an additional amp and subwoofer to their Mark Levinson sound system? I am trying to hook up a Scosche Line-Out Converter with Bass Control and dont know what wires to tap into. Any help is greatly appreciated and thanks in advance fellas!
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
Subwoofer (+) is the #21 Blue Wire on the T40 Plug

The wiring diagram you posted shows that the subwoofer is on #6 and #21 on the T40 Plug. According to the diagram those wires are red and white. You said you tapped a blue wire?
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

The wire colors are different in rc. Blue and gray! Just finished mine.

where did you connect the power and ground coming from the loc2sl
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.

I traded in a 2017 Porsche Macan S with Bose system for my RC-F. The ML system is way better. I also have an Infiniti QX80 with Bose, ML is way better. I used to have a 2016 and 2012 MDX Technology Package with ELS. ML kicks ELS’s butt by a wide margin too. So my question is what OEM system have you heard that beats ML? ML just seems unbeatable. I hope you don’t start naming RR and Bentley because that’s not fair.

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.
