Here is my short step and how I did the speakers. They are in the door panel and not the bottom of the door. Get tired of it and replace door panel. But if you read the thread, it's the 3rd truck I've done that way and getting ready to do the 4th.
Personally, cut the dash, install awesome stereo, move on down the road.
FWIW, when I cut the dash in my Jimmy, dual know radios were still fairly common, but lacking in features even then. My first CD Player cost $750 in 1989 when that was REAL money.
Now you can build a KILLER complete system for $750, and who the heck wants a CD player?! LOL
