What do you mean by "all around?" They should fit easily into the doors, but 5x7 is stock for the back. Although I have heard of people squeezing in 6x9s.
6 1/2" for the front doors (or 5 1/4" with adapter)
3 1/2" for the dash
6"x8" for the rear package tray (coupe) or rear quarter panels (hatchback)
(or 5"x7" with adapter)
not sure about convertible rear
I'ts pretty tight in there. I ended up going with 5 1/4" I believe. They are Boston Acoustic. Even they didn't clear the stock speaker grills, so I made some custom billet ones to give me the extra 1/4" I needed.
YMMV, but for me, Pioneer 6.5" 2-ways fit under the stock grills. 3- and 4-ways from Pioneer fit also, but you're not likely to need that many watts unless youre running an amp separate from your head unit.
