This is the back of left hand door behind which is the Canton subwoofer. I hadn’t looked inside this, but I found it’d opened by itself the other day (and did it again and again!) and so it was lying on the boot floor. So what are these - sound baffles of some sort?
Incidentally, I’ve fixed the opening problem by adding some sticky pads on the bottom lip, which raises the door unit by a couple of mm which is enough to make the lock latch properly.

Aren't they the velcro bottomed corner bracket for holding loads in the boot? Should be 4, 2 stored each side.
