I originally wanted to put in 6x9 but I decided to go with a Kenwood 5x8, because I know the sound I was getting, I used to have them in my old t-bird
I only did the rear doors and the front doors tmro but
didn't have much trouble installing the 5x8s so here is what I did

took panels off not hard once you know how :3
removed old speakers and grill behind them
hammer and fender block (I don't know the name of it forgot) stretched the hole a little
and placed the kenwoods in and screwed them down with self tapping screws there awesome btw
also I took the factory connectors and tied those in with the new speakers wires it came with
install time was about 1.5 hrs because first door was a pain as it was my first time taking them off haha

here is som picks btw
