Additional Notes

  • The front dashboard positions in the 1984 Plymouth Gran Fury accommodate smaller 3.5-inch speakers, which generally limits low-frequency output compared to larger drivers but may still provide adequate midrange and treble response for cabin audio.
  • Full-range speakers represent the compatible type for dashboard locations, meaning single-driver units that attempt to reproduce the entire audible spectrum without separate tweeters or woofers, though this design typically involves compromises in frequency extension at both extremes.
  • The rear deck lid positions accept 6x9-inch oval speakers, a format that provides greater cone area than round speakers of equivalent width, potentially offering improved bass response and overall output capability.
  • Both front and rear locations specify full-range compatibility rather than component or coaxial configurations, suggesting the factory design relied on single-driver solutions throughout the audio system.
  • Rear deck speakers would likely handle most of the system's bass reproduction given their substantially larger surface area compared to the dashboard units, making them a logical priority for replacement when seeking sound quality improvements.
  • The 6x9-inch format in the rear deck may deliver better sound pressure levels at lower frequencies than the 3.5-inch dashboard speakers due to the increased cone excursion area and air displacement capacity.
  • Dashboard speaker replacement could improve clarity in the higher frequencies and vocal range, though the physical size constraint would continue to limit deep bass reproduction regardless of aftermarket speaker quality.
  • The single DIN radio opening indicates compatibility with standard aftermarket head units, which could provide improved power output and signal processing compared to period-correct equipment.
