The front speakers are pretty easily removed, pry off the speaker cover (it is attached with a really sticky gum-like adhesive in 3 places) and un-screw the speaker with a short Phillips head screwdriver. Re-installation is the reverse.
The rear speakers are a little harder but still do-able. Gently pry off the side cover just above the wood trim. I suggest using a medium sized flathead screwdriver covered with a soft cloth or rag to avoid scratching the wood. You are trying to loosen 3 pressure clips located just behind the wood, which are what holds the trim piece in place. (Note- The speaker grille is part of the trim, it will be irreparable damaged if you try to remove it)
Once the trim is off, unscrew the speaker and remove. Note also that the rear speakers are powered by the sub-woofer, in order to get sound from new speakers you will need to run new wire to the new speakers if you aren't replacing with Audi speakers.
I replaced my Audi delta radio with a Blaupunkt and the harness connected the subwoofer fine but as one of my rears was blown, I went with aftermarket speakers and had to wire both apart from the new head unit.
