how big are the speakers
I wouldnt know where to look up sizes of speakers best thing I know to do is take one out and measure it then you will know for sure.
Or check with the dealer most of the times parts are way to high from the dealer but its worth pricing and that way you know your getting ones that fit.
Front doors probably take 5 1/4" Dia. and the rear deck the same and you can also use the 6 1/2" dia. & 6"x9" work as well. You didn't specify a year or if you have the Infinity sounds system or not, so I'm guessing. A good source to see what fits is www.crutchfield.com. Good Luck!
