What size speaker fits in the rears?
The ones in the plastic on the quarters are 5x7 or 6x9?

Anyone know for sure?

 

Hah, you will hear twenty different answers to this question. 6x8 speakers WILL fit the best, as that's what is designed to go there. Apparently many people have fit 5x7 speakers there as well, but why give up the low frequency abilities of the 6x8. Max Cooper also has a nice install write-up on his site.

 

5x7 direct fit...6x8 requires new holes

i'm a part-time audio/ video installer.

definetely go with the 6x8s if you want some *** in your music

 

i got an adaptor plate from crutchfield and am now running 5 1/4 inch mids and it sounds great!

 

6x8's it is. Thanks for your input fellas.

 

I did mine the other day, took the stock speaker the stereo shop and 5x7 was an exact match, screw holes lined up and they fit in the brackets perfectly. I think it depends on manufacturers on whether a 6x8 or 5x7 is the right fitting speaker.

 

you could simply drill new holes for the 6x8s
