Speaker locations on EU model

Does anybody know the exact location of the 8 speaker set up of the EU version of the Gen 3?
So far I have spotted 6 of them (2 in the back doors, 2 in the from doors, and 2 at either extremities of the dashboard).
Where are the other 2 located?
Is there a subwoofer and a central speaker?

I did notice there is an amplifier underneath the passenger seat.
(please note that in EU the 8-speaker set up is not sold as JBL - it might well be it is a JBL, but not sold as so - it simply says 8 speaker option).

 

I have to check again then, I don't remember seeing 2 loudspeakers at the bottom of the rear doors...but then, I never seat at the back...
If the configuration is so, then I must say that the bass, considering that it is a "stock" set up, is not bad at all, and quite well balanced. Again, considering it is a stock set up...
