Additional Notes
- The factory audio configuration in the 1987 BMW M6 positions midrange speakers at 4 inches in the dashboard locations, which suggests these handle the critical mid-frequency reproduction that affects vocal clarity and instrument definition in the listening experience.
- Rear deck lid locations accommodate 6.5-inch speakers rated for either midbass or full-range operation, indicating these positions likely serve as the primary low-frequency source in the original sound system architecture.
- Replacing the dashboard speakers with aftermarket 4-inch midrange units could enhance the tonal balance of the front soundstage, particularly for frequencies where human hearing is most sensitive.
- The 6.5-inch rear deck speakers in the 1987 BMW M6 might benefit from full-range replacements if maintaining a simpler two-way configuration, though dedicated midbass drivers could provide better low-end extension when paired with separate tweeters.
- Component speaker systems would require additional tweeter mounting solutions since the factory specifications don't indicate dedicated high-frequency driver locations in the dashboard or door panels.
- The single DIN radio specification suggests the head unit can be upgraded to modern aftermarket receivers that provide enhanced power output and signal processing to drive replacement speakers more effectively.
- Sound quality improvements would likely be most noticeable when addressing the rear deck positions first, given the larger cone area of 6.5-inch drivers compared to the 4-inch dashboard units.
- Aftermarket speakers for these applications typically feature higher sensitivity ratings and power handling than original equipment, which could translate to increased output levels without requiring external amplification.
