What's the round black grill for in back of the cabin...

...in the bulkhead between the boot and the space behind the driver/passenger - anyone know

They are cabin vents. When you have the blower on, this is where the air exhausts from.

I think if you block them off (as some have done with speakers), sit in a close the door, you get quite a weird pressure thing going on inside the cabin...

Its so that the kids can breathe in the boot

It is hot air only IME....And blows out whenever it wants...... You can close it though, which helps maintain a more healthy 70 degrees in the cabin....:-)
