Forgive me if this was covered elsewhere, but I can't seem to confirm how many speakers the stereo system on a 2022 GLC300 comes with standard. Lots of info on the Burmester optional stereo but nothing on the standard configuration. I also found out today that there are no tweeters behind the grilles closest to the mirrors on the doors. Does anyone know if the wiring harness is behind the door card so that tweeters can be plugged in, or does the Burmester option get its own harness? ZERO information from Mercedes on this, peculiar. Thanks to all for any guidance.
