Additional Notes

  • The dashboard location in the 1990 Mitsubishi Galant accommodates 4-inch speakers classified as midrange units, which typically handle frequencies in the vocal and instrumental spectrum rather than producing deep bass or extreme high frequencies.
  • Both the front door panels and rear deck lid share the same 6.5-inch speaker size, offering flexibility between midbass drivers that emphasize lower frequencies or full-range speakers that attempt to reproduce a broader frequency spectrum from a single driver.
  • Replacing the dashboard midrange speakers might be considered a lower priority compared to the door and deck locations, since the larger 6.5-inch positions generally contribute more significantly to overall sound volume and bass response.
  • The 1990 Mitsubishi Galant features a single DIN radio opening, which may limit aftermarket head unit options compared to double DIN configurations but still allows for substantial audio processing upgrades.
  • Full-range speakers in the 6.5-inch locations would eliminate the need for separate tweeters in those positions, though dedicated midbass drivers paired with separate high-frequency units often produce more detailed sound staging.
  • The three distinct speaker locations suggest a factory audio design that attempted to create a distributed sound field across the cabin, with midrange content from the dashboard and broader frequencies from the doors and rear deck.
