I am considering buying an Audi S3, and I was wondering if anyone has any opinions on a couple of things:

1. The factory fit head unit is wider than DIN, I understand that an adaptor is available to fit standard sized units, how does this work with the empeg docking cage?

2. Audi have an uprated Bose speaker system, including sub that fits around one of the rear wheel arches. This looks like a very neat solution, but is it compatible with the empeg? I can't find any technical details on Audi's webpage and the Bose one is just full of the usual waffle. Alternatively would the 450quid be better spent at cambscaraudio? :-)
