Additional Notes

  • The 1998 Mitsubishi Diamante factory audio system incorporates multiple speaker locations with varying sizes, suggesting a tiered approach to sound reproduction across different frequency ranges.
  • Dashboard tweeters at 1 inch typically handle high-frequency reproduction, potentially contributing to clarity in vocal and instrumental detail when properly integrated with larger drivers.
  • Front door panels accommodate dual size options at 5.25 inch and 6.5 inch, indicating factory variations or upgrade paths for midbass and full-range speakers that handle midrange frequencies and vocal presence.
  • The availability of both midbass and full-range speaker types for front doors suggests flexibility in system configuration, where midbass drivers might pair with separate tweeters while full-range speakers handle broader frequency spectrums independently.
  • Rear deck lid positions accept 6x9 inch full-range speakers, a size commonly associated with extended low-frequency response compared to smaller round drivers, potentially providing bass reinforcement without requiring dedicated subwoofers.
  • Replacing factory speakers in the 1998 Mitsubishi Diamante front doors might yield noticeable improvements in midrange clarity and bass response, as these locations typically receive direct attention from listeners in front seating positions.
  • The oval 6x9 configuration in the rear deck offers greater cone surface area than equivalent round speakers, which may translate to increased output capability and lower frequency extension within the constraints of factory mounting locations.
  • Component speaker systems with separate tweeters and midbass drivers could utilize the existing 1 inch dashboard locations paired with front door midbass units, maintaining the factory's separated frequency approach while improving individual driver quality.
  • Full-range speaker replacements in front doors eliminate the need for separate tweeters, simplifying installation while potentially sacrificing some high-frequency dispersion compared to dedicated dashboard tweeter placement.
  • Both Single DIN and Double DIN radio compatibility provides options for head unit upgrades, with Double DIN allowing for larger touchscreen interfaces while Single DIN maintains traditional sizing with potential storage pocket retention.
