Well between all these, I'd prefer the 6.5" coaxials [JBL CS2165 (2-way coaxials) or GTO637s (3-way coaxials) in front. Save on 4 speakers in front and get the GTO637s. They sound better than the CS2165s.
If you use JBL 4" coaxials in the dash and 6.5" coaxials in the doors. You'll find the setup pretty bright with 4 tweeters in front (tweeters of the 4 coaxials) -- can be fixed a bit by cutting down treble in the HU.
If front soundstage is the criteria I really think you should get 2-way components (CS2165c or GTO607c) in front and nothing else for the front = 6.5" midbasses in the doors and tweeters in the dash.
Good that you can skip the rear speakers
Apply the budget to a 4-ch amp for the fronts and the sub.
