im thinking of putting them where my a pillar meets my dash and using some heavy duty 2 sided tape (3m body tape maybe) so i dont have to drill... also that will make wiring a little bit easier cuz i will only have to run 1 set into the door for my component woofer. also that way, if im not happy with the look or sound quality, i can take them off an put them someplace else without leaving scars.
