Additional Notes
- The 1986 BMW 528e front kick panel and rear deck lid positions both accommodate 4x6 inch full-range speakers, which may allow for simultaneous replacement with matching aftermarket units. This uniform sizing across front and rear locations could simplify the speaker selection process when upgrading the audio system.
- Full-range speakers at these locations would typically handle the entire audible frequency spectrum without requiring separate tweeters or crossovers. The 4x6 inch form factor represents an oval configuration that was common in European vehicle designs during this era, where space constraints often dictated non-circular speaker mounting areas.
- Upgrading from factory speakers to aftermarket 4x6 inch full-range units might result in noticeable improvements in clarity and bass response, particularly if the original speakers have deteriorated over time. Many aftermarket options in this size category offer higher power handling capacity and improved frequency response compared to stock components from this period.
- The kick panel location generally provides better stereo imaging for front passengers than dashboard-mounted speakers, as the sound source sits closer to ear level. Meanwhile, the rear deck lid position typically contributes to overall cabin fill and can enhance the listening experience for rear seat occupants.
- The single DIN radio slot suggests that head unit upgrades would maintain compatibility with standard aftermarket receivers, which could provide additional amplification for replacement speakers. However, power ratings and impedance matching between the head unit and new speakers would need consideration during installation planning.
