hello, you can fit 5x7, 6x8, and 6x9 in the front door speakers(I have 5x7), and in the back, you can fit 5x7 or 6x8(6x9 if you like cutting metal). Also, you will probably have to drill your own holes for the speakers, but that is not really a big deal. As for the hole in the back, it fits either a 6 or a 6.5" speaker, I am not sure. Might be better to just put an 8" in the trunk though.
