Additional Notes

  • The 2004 Mitsubishi Diamante features a multi-location speaker configuration that separates high-frequency and mid-to-low-frequency reproduction across four distinct mounting points.
  • The factory tweeter locations in both the dashboard and front door panels accommodate 1-inch drivers, suggesting a component-style audio design where high frequencies are delivered from dedicated positions.
  • Both front door panels and the rear deck lid utilize 6.5-inch openings that accept either midbass or full-range speaker types, providing flexibility in replacement speaker selection based on whether the system uses separate components or coaxial designs.
  • The dual 1-inch tweeter positions indicate that factory audio configurations may have prioritized stereo imaging and soundstage width through strategically placed high-frequency drivers in the front cabin.
  • Replacing the 6.5-inch locations with aftermarket speakers could potentially enhance overall sound quality, particularly if upgrading from factory full-range speakers to dedicated midbass drivers paired with the existing tweeters.
  • The radio cavity supports both single DIN and double DIN head units, allowing for various aftermarket receiver installations without requiring additional dash modifications.
  • The presence of separate tweeter mounting points suggests that component speaker systems with external crossovers might integrate more naturally than coaxial speakers when upgrading the audio system.
  • The rear deck lid placement of 6.5-inch speakers typically provides fill sound for rear passengers, though their contribution to front-seat listening may be limited depending on cabin acoustics.
