Hey everyone,

I just bought a 2015 E400 Coupe. I'm a high-end audio geek, and I'm already wanting to replace the factory amplifier and Harmon Kardon speaker system with something more "high end" from Focal, Morel, JL Audio, etc. That said, none of the Google searches I have done have led me to a good wiring diagram of the inputs and outputs of the factory amp and speakers. There seems to be better information out there on older E-series models, but I can't find anything for this model year. Does anyone have a good link to get me started? Or a .pdf?

Thanks,
J
