What are the size of the speaker in a '92 LX? I think there are six, 2 front, 2 in the doors and 2 in the back?

 

The door speakers are 5 1/4"
The dash one's are 3 1/2"
and the rear one's are 5x7"

 

6.5" will fit with a spacer in the door. Use the factory grill as a template, copy out of 5'8 MDF and vynal wrap. Looks like factory. If you are looking for an awesome front end look at the Hertz 3 way package (6.5",3" , and tweet). I just installed into my 91 and these are by far the best sounding pkg I've done in a fox body (and I've done a ton in 20 yrs as an installer).
p.s I just pulled 3.5" Bazooka dash speakers and Pioneer 5x7 rears I'll pert with for $60 for all

 

Thank !

I'm looking for something new, I removed my old Alpine set-up and looking for something that sounds better
