Here are the JBL speakers that I used for the rear doors. I have been very happy with them.
As for the front speakers, they are a very strange size. About an 8" opening. The factory speaker is a 6.5" but they have a built in bracket that makes the speaker fit in the big opening. The easy thing to do is to get another set of the Jbl GTO speakers and make an adapter to get them to fit in the bigstock opening. Well it's not very easy.
I found a set of 2 ohm 7" mid bass drivers that I made an adapter for. I'll post up the brand once I remember what it is. Also the front door has about a 3" midrange speaker that I left in and continue to use. As for the two front tweeters, I used some silk domes which are smoother sounding than the factory ones.
