So I managed to figure out how to remove the door panels on the GT.
I successfully upgraded all the speakers. I don't think there are currently any F07 specific guides or information out there on door panel removal at the moment.
Attached is a document that covers my experience - in truth it wasn't too difficult. Just getting the right technique and understanding how it all goes together.
Apologies in advance for typos, grammar etc.
Hopefully this is of use to others.
Stage 1 of audio upgrade complete....
