How to remove the panels in the rear doors

Hi,
Just got my new Passat sedan 1.8T sedan. Drives great, but my sound is not that good as it could be... (I only got the 4 front-speakers factory installed)
So now I want to to put in some extra rear-speakers myself
To do that, I would like to know how to remove the door-panels etc (that is: remove them nicely, so I can still put them back on their place without having to return to my dealer with the broken panel who charges 200 US$ for labour anyway).
As I live in the Netherlands, I can't easely buy at the US online shops who deliver speaker-sets complete with a build-in manual (like crutchfield.com).
Can anyone please tell how-to or send me a manual (preferable with pictures of a disassembled door) on how to remove the panels etc.
Thank you for responding.
Ger
