Additional Notes

  • The 1989 Mercedes-Benz 560SEC dashboard locations accommodate 4-inch midrange speakers, suggesting a factory audio configuration that likely separated frequency reproduction across multiple driver positions rather than relying on single full-range units in the front soundstage.
  • Rear deck lid positions in this vehicle accept 4x6 inch full-range speakers, which handle the complete frequency spectrum from a single driver unit positioned behind the seating area.
  • The single DIN radio opening indicates a standard 2-inch tall head unit installation space, which was typical for European vehicles of this era and affects available aftermarket stereo upgrade options.
  • Dashboard midrange speakers typically reproduce middle frequencies between bass and treble ranges, meaning the 1989 Mercedes-Benz 560SEC factory system may have required separate woofers or subwoofers elsewhere in the vehicle to handle lower frequency reproduction.
  • The 4x6 inch rear speakers represent a different form factor than the front dashboard units, which could result in tonal variations between front and rear audio output due to the different driver surface areas and enclosure characteristics.
  • Replacing the dashboard midrange speakers might offer limited overall sound improvement if the system lacks dedicated tweeters for high-frequency reproduction or sufficient bass drivers for low-end output.
  • The rear deck lid full-range speakers would handle bass, midrange, and treble frequencies simultaneously, though the 4x6 inch size may limit low-frequency extension compared to larger woofer configurations.
  • Front speaker replacement priority might focus on the dashboard midrange units since they typically handle vocal and instrumental frequencies most critical to perceived sound quality in the listening position.
