I have the Symphony package (without Bose) in my '01 A4. I'd like to replace the front component speakers with something easy to install. My goal is the best sound quality and little to no modification to the car. I may decide to add an amplifier at a later date, providing it can be wired easily, but for now it will be powered off the factory radio. Does anyone have recommendations as to what fits easily? I just don't want to cut this thing up and want to keep the "stock" look...

Thanks!
