Remove interior door panels & whats needed to replace speakers in the rear and Whats the stock Speaker size.

newbie questions i know. don't flame, We all gotta start somewhere

 

first roll the window all the way down. take all the screws you can find out, if it has roll up windows, take the handles off, should be a clip behind the handle arm that can be pushed out with a flat head screwdriver. pull the bottom of the door card out towards the inside of the car. there should be some clips that will want to keep it in place, just pry gently so you don't break any of the clips. once you have the bottom loose, push it upward toward the window and it should pop off the door.
