Additional Notes

  • The 2018 Ford Expedition features a multi-location speaker configuration with seven distinct mounting positions ranging from 0.75 inch to 8 inch sizes.
  • Front door panels accommodate 6.5 inch speakers that accept either midbass or full-range drivers, which could serve as primary replacement candidates for sound quality improvements.
  • The system includes dedicated tweeter locations in both A-pillars at 0.75 inch and rear door panels at 1 inch, suggesting a component-based audio architecture in the factory setup.
  • An 8 inch woofer location exists in the rear side panel, potentially providing low-frequency extension that smaller door speakers cannot reproduce effectively.
  • D-pillar positions house 2.75 inch midrange speakers, filling the frequency gap between the tweeter locations and larger door-mounted drivers.
  • The center dash contains a 3.5 inch full-range speaker, which may contribute to center-channel imaging or serve as a fill speaker for the listening position.
  • Rear door panels contain both 1 inch tweeter and 6.5 inch midbass/full-range positions, indicating a two-way component setup for rear passengers.
  • Upgrading the 6.5 inch front door speakers might produce noticeable sound improvements since these positions typically handle the majority of the audible frequency spectrum.
  • The variety of speaker types suggests that selective replacement of specific components could address particular sonic deficiencies without requiring a complete system overhaul.
