Additional Notes
- The 1988 BMW M6 dashboard locations accommodate midrange speakers at 4 inches, suggesting these positions may serve primarily for higher frequency reproduction rather than full-spectrum sound coverage.
- Rear deck lid positions in the 1988 BMW M6 accept either midbass or full-range speakers at 6.5 inches, indicating these locations could handle lower frequency content or provide broader frequency response depending on the chosen speaker type.
- The combination of smaller dashboard midrange units and larger rear deck speakers suggests a factory-designed sound stage that separates frequency ranges between front and rear locations.
- Midbass speakers for the rear deck would likely focus on frequencies between bass and midrange, while full-range options would attempt to reproduce most of the audible spectrum from a single driver.
- The 4-inch dashboard speakers might benefit from replacement first if vocal clarity and instrumental detail in the upper frequencies are priorities, as midrange drivers directly influence these characteristics.
- The single DIN radio opening indicates compatibility with a wide range of aftermarket head units, which could provide improved source quality to drive upgraded speakers in both locations.
- Full-range speakers in the rear deck positions would reduce the need for additional tweeters, though this configuration may compromise high-frequency extension compared to dedicated component systems.
- The size differential between front and rear speakers creates a natural frequency division where dashboard units handle vocals and presence while rear speakers manage lower midrange and upper bass content.
