Sorry to reply to such an old thread - but it's been helpful, so firstly want to say thanks for the tip about the 2 screws because that got me as well. I installed the rears with no problems after reading this thread...

Now I'm up to the fronts - however, I cannot find information on replacing the tweeter in the dash. How is this done? Just pry the cover out? Is wiring hard to this location? Where is the in-line xover or capacitor? Getting the door trims off don't seem to be too bad with the instructions above.

Thanks in advance!
