I just bought an Audi a3 51 reg SE. Comes with a CD player. The audio is terrible and I want to upgrade to an aftermarket system. Ideally want a DAB radio with CD and MP3 player. Did some research and found that the Sony CDX 6650 is going to do the job. I also have a VIBE sub woofer with built in amp that I wish to use and possibly an extra set of 6x9s. Upon futher research, I found that I need a bunch of other accessories to make the thing work as the audi doesnt support RCA outputs and all speakers are amplified etc etc... I think I can find all the stuff cheaply online but I want to get them professionally installed by someone who can do a clean job.. Can anyone please let me know where I shold look for people who would be able to do it for me cheap? A friend of mine got it done from someone who came to the house and did everything required for £40. I dont know where to start looking for someone like that. I lost touch with this friend since.... Any guidance on what I can do with the upgrade on my A3 will also be appreciated. This is the gear I think that will make everything work.

Also, it didnt come with an extra key fob. I want to get an extra one just in case. Has anyone got any ideas on how to get one? I searched on ebay and found used remote fobs with blank keys that I need to get cut myself. I have been told that if I go to Audi directly they cost an arm and a leg. Any help would be appreciated.
