I had a feeling from listening to the systems that the RNS-E had enough quality wattage to actually power good **aftermarket** speakers appropriately. It sounds like your experience confirms it!

That's a good question. The thing with Bose speakers are they are usually weird configurations, like 1 ohm resistance versus the standard 4. I am not sure what is used in the Audi.

front and rear door speakers are mids with separate tweeters like the oem setup but I opted to get kits that did not come with crossovers just because I didn't want to deal with the placement of them. The sound quality is awesome though.
