Hi guys
I have the A4 2004 model. It's the basic concert system. Any advice on how to get the sound so much better? I must admit it's far better than most Manufacturers basic system. I know it's got a small sub speaker in the centre of parcel shelf also. What would be a not so expensive way to get great sound. possibly just change the speakers. Not sure on adding amps but id need be!
Thank for reading post

Hope to hear from you soon.
