Question about speakers

I have a 1993 Geo Prism lsi which i know has the same engine as the corolla and some other stuff are the same to but i was wondering if they both have the same size speaker bay in the back above the rear seat.

as far as i know, no. I checked out the 1993 prizim and 1993 corolla on crutchfield.com and it appears that the geo dosent even ahve a rear dec of speakers. I also found out that the front ones are 4'' and as far as my knowledge the speakers are usually the same all around, I know for my car they are all 6 1/2'' speakers all around jsut like the 1993 rolla, so check me if im wrong. Also if your going to buy from a shop they would know, and you can always remove a speaker to bring in and compare, thats the best advice i can give you.

ya according to the website you gave my car doesn't even have rear speakers so unless i am blind or deaf they are wrong. i remember hearing somewheres that everything inside was pretty much gmc and everything under the hood is toyota so i'll just take the speakers out. thanks alot for your help.
