does anyone know whats the biggest size speakers you can use for the front and rear doors

and what is the stock size? thanks

 

the stock size is 4" front and rear. I replaced all four with a 6.5"

 

do they fit good?

 

Yes the stock size is 4 inches. For minimal modification you can get the 5 1/4 to fit pretty easy. I have 5 1/4 in the front and 6.5 in the rear. 6.5 is going to take quiet a lot of work to fit though. good luck.
