Additional Notes

  • The 1979 BMW 528i uses 4x6 inch full-range speakers in both front kick panel and rear deck lid locations, suggesting that replacing the factory units may benefit from aftermarket options with improved cone materials and higher sensitivity ratings to enhance overall cabin acoustics.
  • Full-range speaker types in the kick panel positions typically handle all frequencies without requiring separate tweeters or crossovers, which could simplify installation while potentially limiting high-frequency extension compared to component systems.
  • The rear deck lid speaker placement in the 528i may receive particular attention during upgrades, as these positions often contribute significantly to perceived sound stage depth when matched properly with front speakers.
  • The single DIN radio opening indicates compatibility with most aftermarket head units, which could provide necessary power and signal improvements to support higher-quality replacement speakers in the 1979 BMW 528i.
  • The 4x6 inch form factor represents an oval configuration that may offer slightly more cone surface area than comparable round speakers, potentially improving mid-bass response within the physical constraints of the factory mounting locations.
