Additional Notes
- The front kick panel locations in the 1980 BMW 733i may present a starting point for sound system upgrades, as these positions typically handle a broad frequency spectrum through their full-range capabilities.
- The 4x6 inch oval form factor in the kick panels tends to fit flush installations while maintaining factory mounting provisions, though aftermarket options in this size class have become somewhat limited in recent years.
- Full-range speakers at the kick panel positions attempt to reproduce everything from lower midrange frequencies through treble, which can lead to compromised imaging compared to component systems that separate frequency duties.
- The rear deck lid accommodates 5.25 inch round speakers, which opens possibilities for either full-range units or dedicated midbass drivers depending on the overall system configuration being pursued.
- When utilizing the rear deck positions for midbass purposes, the speakers would handle primarily lower frequencies while leaving higher ranges to tweeters or the front stage, potentially creating a more balanced frequency response.
- The single DIN radio specification allows for straightforward head unit replacement with most aftermarket receivers, providing modern amplification and signal processing capabilities that can substantially enhance speaker performance.
- The limited number of factory speaker locations suggests that sound quality improvements might depend more heavily on speaker quality and proper amplification rather than adding numerous additional drivers throughout the cabin.
- Kick panel placement typically offers advantages for front soundstage creation, as the speakers fire upward toward the listening position rather than from door-mounted locations that can produce reflections off glass surfaces.
