Additional Notes

  • The 2004 Mercedes-Benz CLK320 includes a tweeter location in the front door panel measured at 1 inch, which suggests a dedicated high-frequency component in the factory audio configuration.
  • Rear side panel positions accommodate 3.5 inch midrange speakers, indicating a multi-driver approach to sound reproduction in the rear listening area.
  • The front door panel locations accept 6.5 inch midbass or full-range speakers, representing the primary sound source for front occupants and a logical starting point for audio upgrades.
  • Behind the rear seat, 6.5 inch midbass or full-range speakers provide low to mid-frequency reproduction, potentially contributing to overall soundstage depth.
  • The presence of separate tweeter, midrange, and midbass locations indicates a component-style speaker system rather than a simple coaxial configuration throughout the cabin.
  • Both single DIN and double DIN head unit compatibility exists in this model, offering flexibility for aftermarket stereo installation alongside speaker upgrades.
  • Replacing the 6.5 inch locations first may yield more noticeable sonic improvements compared to the smaller 3.5 inch midrange positions, given their larger cone area and broader frequency capability.
  • The 3.5 inch midrange speakers in the rear side panels handle a specific frequency band, which means replacement speakers should match this dedicated function rather than attempting full-range reproduction.
  • Aftermarket component sets designed for 6.5 inch applications could integrate with the existing 1 inch tweeter locations, though crossover compatibility would need consideration.
