I need to know the sizes that will fit the front door speakers and the rear speakers of a 94 civic Si hatch!!!! I really need to know, becuase i would like to get 6.5" for the front but i dunno if thats what the other holes are for or what.....the speakers in there now are 5.25" but can i fit larger if i use the other holes?

I would think that they are 6.5". That is what is in my girls 95EX.

 

You can't fit 6.5" in the stock locations.
