Additional Notes

  • The 1988 Plymouth Gran Fury front speaker locations in the dashboard accept 3.5 inch full-range speakers, which represent one of the smaller factory speaker sizes installed in vehicles from this era.
  • Dashboard speakers of this size may benefit from replacement first, as smaller drivers typically provide limited frequency response compared to larger rear speakers.
  • The rear deck lid positions accommodate 6x9 inch full-range speakers, offering considerably more cone area than the front locations for potentially enhanced low-frequency output.
  • Full-range speaker types are specified for both positions, indicating these locations likely function without separate tweeters or external crossovers in the factory configuration.
  • The 6x9 inch format in the rear deck typically provides better bass extension than the dashboard speakers due to the larger woofer cone and increased mounting depth available in that location.
  • Aftermarket full-range speakers in the 6x9 inch size often include integrated tweeters or coaxial designs that could improve high-frequency response over factory components.
  • The single DIN radio opening allows for straightforward head unit upgrades without requiring dash modifications or additional mounting kits.
  • Speaker replacement in this configuration might prioritize the rear deck positions when seeking noticeable sound quality improvements, given the size advantage over the dashboard speakers.
