Additional Notes
- The 1980 BMW 528i utilizes 4x6 inch speakers in both the front kick panel and rear deck lid locations, maintaining uniform sizing throughout the factory audio system. This standardized approach simplifies the replacement process, as a single set of aftermarket speakers could potentially service both locations if identical tonal characteristics are desired front to rear.
- Full-range speakers represent the designated type for these 4x6 inch openings, handling the entire frequency spectrum from bass through treble without requiring separate tweeters or crossovers. This design choice reflects the era's typical audio configuration, where single drivers managed all frequencies rather than employing component setups with dedicated high-frequency units.
- Aftermarket full-range speakers in the 4x6 inch format typically offer improved frequency response and power handling compared to original equipment. Modern replacements often incorporate polypropylene or treated paper cones, rubber surrounds for durability, and neodymium magnets that deliver greater output from the same physical footprint as the factory units.
- The front kick panel mounting position in the 1980 BMW 528i creates a lower soundstage that may benefit from speakers with enhanced mid-range clarity, as this location tends to emphasize vocal frequencies and instrumental presence. The angled installation in kick panels can also affect off-axis response, making speaker design choices particularly relevant for maintaining consistent tonal balance across the listening area.
- Rear deck lid speakers supplement the frontal output but often receive less acoustic treatment in the installation environment. The proximity to the trunk cavity and rear window glass can introduce reflections that color the sound, though this also provides opportunities for increased bass reinforcement if the speakers exhibit appropriate low-frequency extension capabilities.
- The single DIN radio opening accommodates head units with standard ISO mounting dimensions, providing compatibility with contemporary aftermarket receivers that offer amplified outputs. Higher power ratings from modern head units can drive replacement speakers more effectively than original equipment, though attention to impedance matching ensures optimal power transfer and prevents potential damage to either component.
