18mm=.708", 6mm=0.23". 18+18+6=42mm. 2"=50.8mm. Unless your speaker frame is 8mm...
I've made mating spacers for some cars with two 3/4" thicknesses of MDF and one 1/4" thickness of Masonite and a ring that came with the speaker and the speaker itself - plus thick foam weatherstripping tape to close the gap and seal it up.
It certainly can be done. For a DIY guy, it is a good bit of work, and no matter what you say to try to insult the mechanical integrity of the OEM speaker-as-spacer technique, it still is mechanically sound and works very well in a fraction of the time - as Tjhub shows.
If I had a non-Bose Audi B6, B7, or A5 chassis A3, would I use the OEM speaker method? Possibly not. But I do a lot of things in my own car I'm not going to suggest for DIY guys to do, just as you do, because we do them sometimes in the spirit of experimentation, or because we are cranky and contrary and want our cars to be different than the production installs we are involved in more frequently. I suspect the guys who are handy enough to do this figure it out and do it without prompting from us.
At any rate, if someone is making a spacer, it must seal up against the back of the door panel with foam tape to sound its best, and this requires fairly precise fabrication (using the foam to take up the slop). I certainly mis-spoke about the angle, but the points about SQ - ESPECIALLY about the bass quality available from the front door speakers - depend on this sort of installation for maximizing performance.

Crutchfield Speaker Brackets?
These Crutchfield brackets look kinda cheap but are advertised to work for 99-up Audi. Anyone try these (see link)? Still hoping for an easy way out.<ul><li><a href="http://www.crutchfield.com/S-I7RMTIi8V7m/cgi-bin/prodview.asp?I=142SAT6">Crutchfield Speaker Brackets</a></li></ul>
