Help!! Speaker size?

[brekrolla]

I just picked up a 2001 Corolla S and am looking to inhance the audio system. I've been trying to find the exact speaker sizes and have got conflicting information from different sites. One site says that the rear speakers are 6 x 9 's and another that they are 6 3/4 's ? And this makes me question if the fronts are really 7'' as claimed as well. They are hard to access other wise I would just look at them. Can anyone help me out with exact specs whose hooked up there own 2001 or anyone who just knows? Thanks
