- The front and rear door panel locations in the 2020 GMC Acadia share the same 6.5 inch sizing, which may suggest that replacement speakers of the same model could potentially work across both door positions without requiring separate purchases of different sizes.
- The dashboard positions appear to support two distinct sizes, 2.5 inch and 3.5 inch, where the smaller of the two is limited to midrange operation, while the larger may accommodate full-range reproduction across a wider frequency spectrum.
- The 6.5 inch door panel speakers are listed as compatible with both midbass and full-range types, which could indicate some flexibility in choosing between a dedicated midbass driver for low-mid frequency focus or a full-range unit for broader frequency coverage in those positions.
- Given that the dashboard positions are relatively small in size, they would likely handle higher frequency content more effectively, while the 6.5 inch door panel locations could be better suited to carry the lower midrange and bass frequencies, suggesting a natural frequency division across the vehicle.
- Replacing the door panel locations might be considered a higher priority for overall sound improvement, as the 6.5 inch size generally allows for greater cone area and potentially more capable low-frequency and midrange output compared to the smaller dashboard positions.
