Additional Notes

  • The dashboard position in the 1987 Toyota Tercel accepts 4-inch midrange speakers, which typically handle mid-frequency content rather than producing bass or extreme high frequencies.
  • Front door panels accommodate 6.5-inch speakers, offering potentially the most substantial sound improvement due to their larger cone area compared to the dashboard location.
  • The rear deck lid accepts 5.25-inch drivers that can function as either midbass or full-range units, depending on system configuration and crossover settings.
  • Replacing dashboard midrange speakers might provide noticeable vocal clarity improvements, though their 4-inch size limits low-frequency output capability.
  • Full-range speakers in the door panel positions would handle the complete frequency spectrum without requiring additional crossover components or separate tweeters.
  • Midbass configurations in both door and rear deck locations would typically require pairing with separate tweeters to maintain high-frequency response.
  • The door panel speakers likely warrant priority consideration for upgrades given their 6.5-inch size advantage and proximity to listening positions.
  • Factory single DIN radio dimensions suggest straightforward aftermarket head unit replacement without requiring additional mounting modifications.
