Mercedes-Benz C-Class speaker upgrade

Older C-Class sedans take common door sizes, which makes them easy to upgrade. C-Class models from 2006 to 2014 take 6.5 to 6.75-inch speakers in the front doors, and 2006 to 2007 models take 5.25-inch speakers in the rear doors. From 2015 on, and for the other spots, the C-Class needs a check at the shop. We have verified sizes for 4 of 8 year ranges or trims in our table; anything not verified says "Confirm fit at the shop".
