Additional Notes

  • The 1987 Cadillac Eldorado factory audio system includes three distinct speaker locations with different size configurations throughout the cabin.
  • The front door panels accommodate 4 inch midrange speakers, which typically handle vocal frequencies and mid-level tones rather than full frequency reproduction.
  • Dashboard positions utilize 4x6 inch full-range speakers that may process the complete audio spectrum from a single driver unit.
  • Rear deck lid locations feature 6x9 inch full-range speakers, representing the largest factory speaker size in this configuration.
  • Upgrading the rear deck speakers could potentially provide the most noticeable improvement in bass response and overall volume due to their larger cone area compared to other factory locations.
  • The midrange-only designation for door speakers suggests a multi-speaker approach where different locations handle specific frequency ranges rather than independent full-range reproduction.
  • Aftermarket replacements would need to match the physical dimensions at each location, with consideration for whether full-range or component speakers are preferred.
  • The dashboard speakers may contribute to stereo imaging and high-frequency clarity given their forward-facing positioning relative to occupants.
  • The single DIN radio opening allows for replacement head units with modern features while maintaining compatibility with the factory mounting space.
