If you get the upgraded sound system, there are 12 speakers (standard has 7). Where are they? I see two on the A-pillars, four on the doors, and two at the very back on the lift gate. That's eight. Assuming there's a subwoofer somewhere, that's nine. I didn't count the grill that you see on the ceiling near the rear view mirror, as I just think that's the mic for voice commands and phone calls, but I'm not sure. I thought maybe there were some speakers under the grill where the defroster vents are, but it doesn't look that way in the pictures I've seen of the defroster fix/refit that some people got. What am I missing?
