The car is too new and no one has speaker boxes for it. Since I don't have the car, I asked another member to estimated trunk dimensions. This is purely DIY at the moment.
I don't even have the car so I can't give you any facts, but with some searching I found other owners have confirmed 6.5" for the doors and at least 1" tweeter.
You've got to research this stuff. We're doing this on our own as well. Much of the stuff has been asked many times, and you can find answers using the forum search. Without the search button, the same question will be asked over and over again.
I would suggest the DIY subforum for some pictures and information posted from other owners in regards to their stereo installation.
Enjoy!!! I wish I had my Z so I can do work on it as well.
