DIY: Front speaker replacement

[Eggman]

Are the rear speakers in the rear doors?

Yes and

And is the installation procedure exactly the same as the procedure for the front speakers?

Pretty much, except for a few less wires to get in your way.

I replaced all four speakers and detailed the install in Speck's Garage entry here. The subsequent posts include lots of pictures and details of how I went about the changeover and mistakes made along the way.
