Definitely 6.5"
The rears, however, will vary from car to car. Some 5th gens are 6.5" all around, some have 6x9" in the back. I'm not even sure if there is rhyme or reason to it depending on year or DX/LX, etc. If you are changing the rears too, make sure you open the trunk and look before buying new ones.
BTW, am I correct in assuming the 7th gen has 6.5" up front too?
