Audi A3 speaker upgrade

New door speakers are a simple first upgrade in an A3. A3 models from 2006 to 2013 and 2015 to 2020 take 6.5 to 6.75-inch speakers in the front and rear doors, and 2015 to 2020 models also have a 3.5-inch center dash speaker; 2014 and 2021 and newer need a check at the shop. We have verified sizes for 3 of 6 year ranges or trims in our table; anything not verified says "Confirm fit at the shop".
