Hey I drive a 88 gt hatchback and i was wondering what size speakers where in the front door and the backseat. Im not sure if the front is 5.25" or 6.5". anyone drive a foxbody that could contribute here. I think the back is either 5x7 or 6x8 but im not sure. Also im not near my car because im at school or else i would go outside and measure myself. Thanks for the help guys

 

5x7 isn't it? Mustangs have been for a while I thought...

 

not absolutely sure, but i think the fronts are 5.25. 5x7 in rear for sure. some had 3.5s in the dash too

 

I think 3.5 in the dash and 5 x 7 all around.......

 

Im 95% sure thats what it is...

 

you need to remove the deck and look below it to see if there is an amp and a premuim system. They are easily bypassed if you know how, be happy to help when you get to that point.
