Do a seach...but honestly, if you're replacing all the speakers in your car it won't really matter what the current stock spkr sizes are. I can tell you that the rear deck uses a 6.5" with a 1" tweet I believe. The front doors have a 3-way system so those need to go. You shouldn't have too much trouble fitting a 6.5" in front, a baffle and minor modifications will need to be made at most. I would however, be concerned with the HEX midrange mounting depth as it could possibly hit the window when it is retracted.
