Hello all, new to the board.  I've been the owner of a beautiful 2002 Impreza RS for about 4 months now, and its time to upgrade the stereo.  The guy at circuit city said I didn't need a mounting kit, that my deck should fit (It is a Pioneer Premier w/ removable face.) 
  
I've done plenty of stereo installs before, and the wiring should be no problem.  My only question is where do I start to take apart the dash around the stereo?  Are there a few simple screws to undo, or do I have to take off the entire dash? 
  
Thanks!
