Simple upgrade from stock

[burns420]

I cant seem to find much info on this, but maybe Im just new to it and dont know what im looking for. I have an 03 A4 sedan with non bose, non Nav. Is it symphony I or II? If I just want to upgrade the sound, can I just change out the front and rear door speakers to different components and expect better sound?

If you're looking for a "simple upgrade" I would recommend adding a 4 channel amplifier and replacing the speakers.

in some cases yes.. but with most modern cars the speakers are pretty decent as it is..

like said before you will prob have to get an amp and new speakers will help when you get a new amp
