Additional Notes

  • The 2018 Dodge Challenger utilizes two different speaker sizes throughout the cabin, with smaller 3.5 inch units positioned in the center dash and dashboard locations, while larger speakers are installed in the door panels and rear deck.
  • Front door panel speakers feature 6x9 inch oval configurations designed as full-range drivers, which may offer broader frequency response compared to the smaller round speakers found in the dash positions.
  • Rear deck lid installations accommodate 6.5 inch speakers that can function as either midbass or full-range units, providing flexibility in component selection based on whether the system uses separate tweeters or relies on full-range integration.
  • The dashboard and center dash positions both specify 3.5 inch full-range speakers, which typically handle mid-to-high frequencies and contribute to overall soundstage width when positioned across the front of the cabin.
  • Upgrading the front door panel speakers might be considered a priority given their larger 6x9 inch size, as these locations often provide the primary output for midbass frequencies and overall sound pressure level in many factory audio configurations.
  • The dual compatibility rating for rear deck speakers suggests these positions could accommodate either dedicated midbass drivers in a component system or full-range speakers in a more basic configuration, depending on the chosen audio setup approach.
  • All specified locations utilize full-range capability at minimum, indicating the factory system likely relies on these speakers to reproduce a wide frequency spectrum without necessarily requiring separate crossover networks for basic operation.
