1- did you do it yourself, or have it professionally installed?

2- what are they going for?

3- How do they sound?

Recommendations?

Thanks!

Phatbox fantastic - they sound great.
I got mine for $650 on eBay. But clairparts.com (electronics)has had them on sale for as low $460 past xmas (Currently $750). If you call them you might be able to negotiate a better price that the one listed.

Install varies in price. If you have provisions for a in trunk CD changer(cable and mounting bracket) it is a piece of cake. You can easily do it yourself. However, in my '03 A6 I have an in dash CD changer so I don't have the cable but I do have the bracket under tool kit. So you need the cable for $95. And since the cable needs to be run from trunk to back of radio the install is a little more complex. There are posts on install proceedure. Also if you go to Phatnoise website and look under Audi you will find a download of instructions for install.
I had mine installed at Audi shop $200.<ul><li><a href="http://phatnoise.com/audi/installation_guides.htm">Install proceedures</a></li></ul>
