I'm installing aftermarket speakers in my 2013, and when I get get to the passenger door, the speaker is connected with grey/white and grey/black. I can't seem to find any wiring diagrams that show this, Is it safe to assume the grey/black is ground (-)?

I can't verify on smart since I haven't messed with stero/speakers yet, but on 99% of the cars I've swapped speakers that was the case. Color/black always was the ground.

I don't know that either wire is technically 'ground' - I'd expect the speaker to be driven by a differential signal, i.e. both are 'live'.

I think what you are really asking is in regards to speaker phase. The info I have shows the following for the non-premium sound system.

Left Door Speaker:

Terminal 1 = BRN/GRN at speaker = BRN/GRN at radio = '-'
Terminal 2 = GRN at speaker = GRN at radio = '+'​

Right Door Speaker:

Terminal 1 = GRY/WHT at speaker = ORG/BRN at radio = '-'
Terminal 2 = GRY/BLK at speaker = ORG at radio = '+'​

Thanks, Toaster. That was exactly what I meant. I knew it sounded strange, I figured it may be out of phase. I'll need to swap the connections, then.
