Additional Notes

  • The 1988 Plymouth Caravelle front audio locations accept 3.5-inch full-range drivers, which represent one of the smaller standard speaker formats available in aftermarket automotive audio.
  • Dashboard speaker replacement in this configuration tends to be prioritized lower than rear deck installations due to the limited low-frequency output capabilities of 3.5-inch drivers.
  • The rear deck lid positions accommodate 5x7-inch full-range speakers, a size that offers broader frequency response compared to the dashboard units.
  • Full-range speakers in both locations handle the entire audio spectrum without requiring separate tweeters or crossovers, simplifying installation procedures.
  • The 5x7-inch format is interchangeable with 6x8-inch speakers in many cases, potentially expanding replacement options for the rear deck positions.
  • Sound improvement potential is generally higher when upgrading the rear deck speakers first, given their larger cone area for moving air.
  • The single DIN radio opening allows for head unit upgrades that can provide additional power to drive aftermarket speakers more effectively than factory amplification.
  • The size difference between front and rear speakers creates an inherently rear-biased soundstage in the factory configuration.
  • Aftermarket full-range speakers in the 5x7-inch size often feature polypropylene or treated paper cones with sensitivity ratings between 88-92 dB.
  • The 3.5-inch dashboard locations may benefit from speakers with enhanced midrange voicing to compensate for limited bass extension.
