Additional Notes
- The 1987 BMW 528e utilizes 4x6 inch full-range speakers in both front kick panel and rear deck lid positions, creating a symmetrical speaker configuration throughout the cabin that may simplify the replacement process when sourcing aftermarket components.
- Full-range speaker types are specified for all locations, suggesting that the factory audio system was designed without separate component configurations or dedicated tweeters, which could allow for potential upgrades to component systems if the kick panel location provides adequate tweeter mounting options.
- The front kick panel placement typically positions speakers near the floor and angled toward occupants, which may affect soundstage characteristics compared to door-mounted installations, though this location can sometimes provide benefits for mid-bass response in certain listening conditions.
- Rear deck lid speakers in the 1987 BMW 528e would likely contribute to rear-fill audio, and the 4x6 inch size represents a relatively common rectangular format that offers more cone area than a 4-inch round speaker while fitting in constrained mounting spaces.
- The single DIN radio specification indicates a standard head unit size, which may limit factory integration features but provides straightforward compatibility with a wide range of aftermarket receivers that could improve source quality and amplification for the speaker system.
- When considering speaker replacements, the 4x6 inch format offers numerous aftermarket options across various sensitivity and power handling specifications, though attention to mounting depth and adapter brackets may be necessary depending on the specific kick panel and deck lid cavity dimensions.
