Fair enough - I was as you say 'looking for a shortcut' to speed up the process a little. And noooo way am I using the factory speakers! :-) I replaced them with Focal 165A up front, and Alpine in the back + JL Stealtbox 10" sub. I am going back to my audio dealer to get some minor issues resolved, and we are going to use the "IASCA setup & test" tracks to set the levels - thanks for the tip, I re-ripped it into WAV instead of mp3 for the testing. If anyone wants a copy for their own use, let me know - I ripped it right from the original.
