Well, got the MB Quarts fitted today. The autoleads front adapter rings were a wee bit naff, not as good as the MB Quart adapters for the A4. They were nice. /ubbthreads/images/graemlins/cool.gif Anyway, I had to use the wee clips (the ones you use for thin parcel shelf fittings) that come with the speakers to actually attach them to the adapters (woofers). Not brilliant, but it seems to work ok. The tweeters in the S3 are sublty different from the A4, so the pressure clip required a little, ahem, modification and the MB Quart stickers came in useful to pad out the tweeter a bit. Tis going nowhere now. Routing cable through the door is ok, have to take the glove box out passenger side, but it's ok driver side. Some hassle taking it across the centre console. Fired it up, sounds great! Forgot how good those quarts were. Have a bit of noise though and turn off thump so relays ordered to cure that. Will see how the noise goes. Thanks for listening.
