Sorry to redo something to death: This post is a bit of a beast - sorry. I didn't look on here before buying my 20th Dec 2000 8L S3, and went for Bose as I assumed it would sound sweet - and it is in fact quite poor. I am not looking to spend serious cash, but I am looking to slowly replace various elements to improve sound quality, etc. Basically, I was wondering whether the following plan of action works - or whether I need to take anything else into account: 1. Stopping bose equaliser I snipped the greenish wire labelled G on rear of HU. I assume this is the gala wire (there was no bose labelled wire), and that I'm not hearing things if I say the treble has increased? 2. Replace HU with aftermarket I don't want Ipod or cd changer - but I would like MP3 readability and bluetooth phone. I'm considering the Blaupunkt Hamburg MP68 - display changes nicely to red. In order to fit such a unit I believe I will need: http://www.nexxia.co.uk/Car_Stereo_fitting_kits/Audi/A3.htm My facelift car is registered as 20/12/00 - therefore I in in a quandary on which fascia adaptors I need? Aftermarket HU has 3 x pre-outs, so I guess cheaper wire adaptor is an option? 3. Replace Front speakers Front passenger speaker suffers from intermittant buzzing at all frequencies. I intend to replace both front speakers first off, both to lose this fault and improve sound quality, before seeing what else could be the problem. I understand I will need speaker adaptors - which I understand will allow me up to 5.25" speakers. Can I buy tweeterless speakers and plug them into the crossover - therefore using the existing tweeters? Are there any aftermarket component speakers where the tweeter can be positioned inside the existing door card tweeter housing? 4. Replace sub I have an Alpine 1600 active sub - but I'm told it will be too small for an S3 -- is it worth me testing it out - Otherwise, I would prefer amp to be hidden as per existing Bose amp, so an Andymac stealth effort seems like the best option -- Andymac, what is your fully fitted quote on that again? Thanks for any help.
