Additional Notes

  • The 2018 Ram ProMaster City features a two-component speaker arrangement in the front listening area, with tweeters positioned in the A-pillars and larger drivers mounted in the door panels.
  • A-pillar tweeters at 1 inch may represent the factory mounting locations designed specifically for high-frequency reproduction, separate from the door panel midbass duties.
  • The 6.5 inch door panel openings accommodate either dedicated midbass drivers or full-range speakers, suggesting flexibility in component system configurations depending on whether the A-pillar tweeters are utilized.
  • Replacement speakers for the front doors would likely provide the most substantial improvement to overall sound quality, given their size advantage and broader frequency response capabilities compared to the smaller A-pillar units.
  • Component speaker systems designed with separate tweeters and midbass drivers could integrate naturally into the existing architecture, maintaining the factory separation of frequency ranges between the two mounting locations.
  • The radio opening accepts both single DIN and double DIN head units, offering compatibility with a range of aftermarket receivers that could enhance amplification and signal processing for upgraded speakers.
  • Full-range speakers in the door positions might serve as a simpler upgrade path, potentially eliminating the need to replace or retain the A-pillar tweeters while still improving fidelity and output.
