What Size Speakers Are in a 2006 Nissan Altima?
The 2006 Nissan Altima (L31 generation) uses 6.75-inch (often called 6.5-inch compatible) speakers in front doors. Rear deck holds matching 6.75-inch units.
I’ve pulled dozens of these. No dash speakers stock, just door and parcel shelf. Measure your own: remove door panel, check magnet diameter—6.5-6.75 inches standard.
Crutchfield confirms: Exact fit for JL Audio C2-650 or Rockford Fosgate Punch replacements. Avoid undersized; they rattle.
