The opening of the plastic cover or door panel is just about 6.5 give or take. If he goes bigger the cone surround could hit the back of the door panel.

spacer will accomodate for basket width by default, i put a set of hertz hsk165xls in a 2011 whcih are only 2mm shallower than the legatias than he will have no trouble fitting legatias in his factory location without hitting the door.

A mid in the tweeters stock location could be very very close. Right under the tweeters bracket about 1/4 inch down is plastic so I am not sure if you are going to have clearance for a mid.

If you are seriously going to do a 2 or even 3 way setup I would highly recommend going with either a audison bitone or the more popular option the JBL MS8.
