I was reluctant to start pulling my dash apart as well, but once I just dove in, it really wasn’t that bad.
Two screw above the radio, then that trim around the radio and vent comes off. There is an additional screw under there too. Above your gauges there are two screws that go up towards the dash. That is all that I remember- I think that is it. Next get a trim tool or be gentle with a screwdriver and pry out the entire trim piece that covers your speedo and vents (this pulls out towards you). On the right side there will be two dash lights then unscrew a quarter turn and your 4wd selector to unplug. This should allow you to move it to the side and gain access to the top of your speaker.
