Hi everyone, 1st time poster, just purchased a 2003 A4 1.8T. I did lots of shopping round and although i wanted one with a BOSE upgraded stereo i settled for one without. I just wonder what have i missed out on? 1) Is the BOSE upgrade really that good? 2) What comes with it? 3) Is the Symphony CD player i have in there actually BOSE? 4) Finally i have some 17" Pioneer speakers i put in my last car and have taken them out. I may put them in my new car but can anyone offer advice on fitting them etc? Thanks in advance.
