Protege Stereo
 

I am trying to replace my stereo in my 2001 Protege. Im a little nervous doing it because I dont know anything about this kinda stuff. My problem is that I got the face plate off of the dash but I cannot get it to seperate from the a/c contol box at the bottom of the face plate. Im affraid of breaking either the face plate or the controls.
Anyone know how to solve this Problem????
