i bought the adapters from ebay, havent put them in yet, so i dunno. my parts car has 6x9's in the door, i havent inspected them, so i cant tell you if theres somthing special you have to do. but yeah, it can be done. the corner of the door panel does stick out a little, but not much to make a difference

You should really go with the 6.5" over the 6x9" because the odd speaker shape does not produce sound waves as accurately as the round speaker. Plus, most companies don't make high-end speakers in the 6.9" category so it's going to be lackluster to say the least. Just a tip...

If you don't want to buy speaker adapters you can always use a jigsaw to increase the opening in your S13 door panel for a 6.5" speaker. I did that with my old Nissan Maxima and it worked like a charm.
