6.5 inches
6.5 in the back
30
The rear speakers are the same size of the front. 6.75" but 6.5" will work also
The door speakers in Geo Prizms From 1993-1997 and possibly newer are 4in. and the rear speakers are 6.5in.
4inch in front r-l grill easy installation but very shallow
At least fot the 96 its a 6 and one half inch speaker.
Yes.
For my 94 Geo Prizm it's a 30mm.
remove the rear seat (bottom) pops right out from front. remove the rear seat (back) two nuts on the floor. the rear speaker deck slides out.
The front speakers are 4.75" (yes, a non-standard size) and the rears are 7.0" (you guessed it, another non-standard size). 4.5" aftermarket speakers will fit the front with some additional foam baffling round them to make them air-tight and 5.25" and 6.5" speakers will fit the rear with a Scosche adapter bracket. I have 6.5 inch Pioneer speakers in back. I just screwed the new speakers in the stock mounts and it worked fine.
Rear deck speakers are 6" or 6 1/2" and the door speakers are 4"
Yes the Geo Prism has ait bags.
