Additional Notes

  • The 2022 Acura RDX features a multi-location speaker configuration with nine distinct positions throughout the cabin, ranging from 1-inch tweeters to an 8-inch subwoofer location.
  • Front door panels contain dual speaker positions at 3.5 inches and 6.75 inches, suggesting a component-style setup that separates midrange duties from midbass frequencies.
  • The 1-inch tweeter locations in both the headliner and pillar positions likely handle high-frequency reproduction above the crossover point of the larger drivers.
  • Six positions are allocated to 3.5-inch drivers across the center dash, D-pillar, front doors, and rear headliner, indicating this size handles significant midrange coverage in the factory audio configuration.
  • The 6.75-inch locations in both front and rear doors can accommodate either midbass-specific drivers or full-range designs, offering flexibility in component selection during replacement.
  • A dedicated 8-inch subwoofer position in the rear suggests the factory system includes low-frequency reinforcement separate from the door-mounted speakers.
  • The presence of D-pillar midrange speakers at 3.5 inches indicates rear-focused sound staging, potentially for rear seat passengers or ambient fill.
  • Replacing the door-mounted 6.75-inch speakers would likely yield the most noticeable improvement in overall sound quality due to their midbass and full-range responsibilities.
  • The center dash full-range speaker at 3.5 inches may contribute to vocal clarity and center imaging for front occupants.
  • Component speaker systems designed for this application would need to match the existing tweeter size of 1 inch and midbass size of 6.75 inches for proper fitment.
