Additional Notes

  • The 1990 Audi 100 dashboard positions accommodate 4-inch midrange speakers, which typically handle vocal frequencies and instrumental clarity in the middle of the audio spectrum.
  • Rear deck lid locations support 6.5-inch speakers that can function as either midbass drivers or full-range units, offering flexibility in system configuration.
  • Replacing the dashboard midrange speakers could enhance vocal reproduction and detail in the front soundstage.
  • Midbass-capable speakers in the rear deck positions would strengthen lower frequency response without requiring a subwoofer installation.
  • Full-range speakers in the 6.5-inch positions would provide broader frequency coverage from a single driver design.
  • The single DIN radio opening allows for aftermarket head unit upgrades while maintaining compatibility with standard sizing.
  • Component speaker systems with separate tweeters might complement the 4-inch midrange positions for improved high-frequency extension.
  • The rear deck installation could benefit from speakers with higher sensitivity ratings to maximize output from factory amplification.
