6th Gen Speaker Size

[pipwud]

Hey. I'm having some minor difficulties finding the speaker size in my celica. I ran through the Chilton's manual and I have a strong feeling I'm running it by.. And Crutchfield, when outfitting my car, came up with two different sizes for the rear panel speakers alone.

Was just hoping someone on here knew them off the top of their head and could lay it out for me, would be much appreciated.

It's a 1994 Celica ST, hatchback.
I also saw a post that some guy with a 96 celica has 6 speakers.. I believe that is the same Gen as my car but I only recall 4 speakers (two in doors, two in the back seat) total.

Thanks!
