I have just removed front door panels to access the font speaker boxes and am now moving on to the rears the question is How do I get to them and what size are they?

Just start taking out all the screws you see on the back half of the car...those two big panels will come out eventually.

6.5" Just pop the grille off with a screw driver not scratching the plastic. Three screws and the speakers come out. The factory uses a little glue, so a flat screw driver sometimes helps. You don't need to remove the interior trim unless your new speakers do not fit the factory box. Then you would have to remove everything to do what is needed.
