I don't think that has ever been asked before since that system is on the rare side. I would think it would be simple enough. Take door panel off and replace. As I remember, there Are no crossovers or anything complicated.
Do you want to upgrade the speakers or replace with stock? If the latter, you can rebuild the OEM speakers with new foam. DO NOT throw away the old speakers (or, for that matter, any part for this car). As for removing the door trim ring/door panel, I was able to install the speakers without fully removing the panel.
