Additional Notes

  • The 2014 Mercedes-Benz C250 includes 1-inch tweeters in both front door panels and the rear deck center, which handle high-frequency reproduction separately from the larger drivers.
  • A 3.5-inch full-range speaker in the center dash position provides mid-range frequencies, likely supporting dialogue clarity and center-stage imaging in the factory audio configuration.
  • Both front and rear door panels accommodate 6.5-inch drivers that accept either midbass or full-range speakers, offering flexibility depending on whether the system uses component or coaxial configurations.
  • The rear deck center location houses an 8-inch subwoofer for low-frequency extension, which may be the first component to consider upgrading if bass response requires improvement.
  • Component speaker systems with separate tweeters and midbass drivers could integrate with the existing 1-inch tweeter locations, while coaxial speakers would consolidate drivers at the 6.5-inch positions.
  • The factory system distributes seven speaker locations across tweeters, mid-range, midbass, and subwoofer positions, indicating a multi-way configuration rather than a simple coaxial setup.
  • Aftermarket head units supporting either single or double DIN form factors maintain compatibility with the factory radio opening if source unit replacement becomes necessary.
