Additional Notes

  • The D-Pillar and Dashboard both share a 2.5 inch cutout size, which suggests that a midrange driver installed in either location would likely handle the same frequency band, potentially contributing to a more consistent upper-frequency presentation across the cabin of the 2020 GMC Yukon.
  • The Dashboard also accommodates a 3.5 inch full-range driver as an alternative to the smaller 2.5 inch midrange option, meaning there may be some flexibility in how the front soundstage is configured depending on which size is selected.
  • The Front Door Panel accommodates a 6x9 inch full-range driver, which is generally a larger format than the 6.5 inch cutout found in the Rear Door Panel, suggesting the front doors may carry a greater portion of the low-to-mid frequency output relative to the rear.
  • The Rear Door Panel supports both midbass and full-range driver types in a 6.5 inch format, indicating it could be oriented toward reinforcing lower midrange frequencies or serving as a secondary full-range source depending on the type of driver installed.
  • Given that the Front Door Panel holds the largest driver format at 6x9 inches with full-range compatibility, it could be considered a higher priority location when addressing overall sound reproduction, as it may have the widest frequency coverage potential among all listed positions.
  • The combination of midrange drivers at the D-Pillar and Dashboard positions alongside full-range or midbass drivers at the door panels suggests the factory speaker layout may have been distributed across multiple zones to cover different parts of the frequency spectrum.
