Additional Notes

  • The 1998 Subaru Legacy positions all four door panel speakers at the 6.5 inch size, creating straightforward replacement opportunities across both front and rear locations with matching speaker components.
  • Each door location accepts either midbass drivers or full-range coaxial speakers, giving installers flexibility in choosing between dedicated component systems or simpler coaxial configurations depending on audio goals.
  • Midbass drivers typically handle frequencies from approximately 80 Hz to 3 kHz and require separate tweeters for high-frequency reproduction, while full-range speakers incorporate both woofer and tweeter elements in a single unit.
  • The uniform 6.5 inch sizing throughout the 1998 Subaru Legacy simplifies speaker selection when upgrading multiple locations, as installers can potentially use identical models at all four positions.
  • Full-range coaxial speakers may provide a more economical upgrade path since they include integrated tweeters, whereas component systems with separate midbass drivers generally require additional tweeter mounting and crossover installation.
  • The Single DIN and Double DIN radio compatibility suggests the head unit cavity can accommodate either standard-height or taller aftermarket receivers, potentially supporting models with built-in amplification or advanced signal processing.
  • Component speaker systems using midbass drivers in the door locations often deliver improved sound staging and frequency separation compared to coaxial configurations, though installation complexity increases with the need for separate tweeter placement.
  • The 6.5 inch format generally provides adequate cone area for mid-bass response in door panel applications while remaining compatible with most factory mounting locations without requiring significant modifications.
