Audi (80) Cabriolet rear speakers

Ok...I managed to work it out, although I have now discovered the speakers I bought are too small. But as far as removal, this is the process.

Remove the panel from the top

what size are the standard speakers please? as there crap and would like to fit better ones!
 
I can't remember now. 10cm front and 12.5cm rears I think. The sound quality still isn't amazing, but it's improved.
