Audi A4 speaker upgrade

New door speakers are one of the easiest upgrades in an A4. A4 models from 2010 to 2023 and 2009 sedans take 6.5 to 6.75-inch speakers in the front and rear doors, and 2006 to 2008 sedans take 6.5 to 6.75-inch speakers in the front doors. 2007 to 2009 convertibles take 6.5 to 6.75-inch speakers in the rear side panels, and the 2006 wagon takes 6.5 to 6.75-inch speakers in the front and rear doors. The 2007 to 2008 wagons, the convertible's front doors and the rear of the 2006 to 2008 sedans need a check at the shop. We have verified sizes for 4 of 5 year ranges or trims in our table; anything not verified says "Confirm fit at the shop".

It depends on the year. Some we have verified: 2010–2023: 6.5" or 6-3/4" in the front doors, 6.5" or 6-3/4" in the rear doors; 2009 (Convertible): 6.5" or 6-3/4" in the rear side panels; 2009 (Sedan): 6.5" or 6-3/4" in the front doors, 6.5" or 6-3/4" in the rear doors.

Do I need a new radio or an amp to upgrade the speakers?

Not always. New speakers can run off the factory radio. Some factory premium systems use an amp that needs an interface; we check your trim before you buy.
