All comes down to budget really. Focal/Morel are good high end speakers. I've got a set of 3 way focals for sale at the moment.
Or just go for a pair of 6.5" components, no real need for 3 ways. You'll need a decent amp too, assuming you get the doorpods right and the doorcards attached properly with a decent amp and headunit it'll sound 10 times better than 4" speakers in the dash and large rears.
