Answer
Best place to get this technical data is from

www.crutchfield.com

and work through their "outfit my car" sequence.  It will help you in finding replacement speakers that will fit the spaces in your 02 Grandprix.

The door panels will have to come off to get into the front door mounted speakers.  There are pictorials that you can find on the Internet with a google search for them.  The back deck speakers can usually be removed from the trunk, but you must look at the mounting hardware with a flashlight to see exactly which method is used as I don't remember this model.  Some mount from the top and some from the bottom.  Some, the hardware screws off from inside the trunk but the speakers lift out from the top, etc.

Best wishes with your project.
