Additional Notes
- The 1985 BMW 528e uses 4x6 inch full-range speakers in both the front kick panels and rear deck lid locations, suggesting a uniform speaker configuration throughout the cabin that may simplify replacement planning when addressing multiple positions simultaneously.
- Full-range speakers in the kick panel positions typically handle the entire frequency spectrum from a single driver unit, which means replacement speakers with integrated tweeters or coaxial designs could maintain the factory audio architecture without requiring separate high-frequency components.
- The rear deck lid placement of 4x6 inch speakers indicates that sound dispersion from the 1985 BMW 528e rear stage likely projects upward and forward, a mounting strategy that can influence staging characteristics and the perceived soundstage depth during audio system upgrades.
- Aftermarket 4x6 inch speakers are commonly available in both coaxial and component-style configurations, offering flexibility in replacement approaches depending on whether the goal involves maintaining simplicity or pursuing a more detailed sound presentation.
- Kick panel speaker locations often present installation challenges due to limited depth clearance and angled mounting surfaces, which may require careful attention to the mounting depth specifications of replacement speakers to avoid interference with trim panels or passenger footwell space.
- The single DIN radio opening provides compatibility with a wide range of aftermarket head units, which could serve as the foundation for an audio upgrade strategy that precedes or accompanies speaker replacement to address source quality before transducer selection.
- Replacing speakers in pairs rather than individually tends to maintain tonal balance across the left and right channels, particularly when moving from factory speakers to aftermarket units that may have different sensitivity ratings or frequency response characteristics.
