Additional Notes

  • The dashboard speakers in the 1989 Plymouth Gran Fury are positioned at 3.5 inches, which tends to handle mid-range and higher frequencies rather than providing bass response.
  • Full-range speakers for the dashboard location would likely reproduce vocals and instrumental detail without requiring additional components.
  • The rear deck lid accommodates 6x9 inch speakers, a size that generally provides more surface area for sound reproduction compared to smaller round speakers.
  • Full-range 6x9 speakers could deliver lower frequency response than the dashboard units due to their larger cone area.
  • Replacing rear deck speakers might offer a more noticeable improvement in overall sound output than dashboard replacement, given the size difference.
  • The single DIN radio configuration suggests standard aftermarket head units would fit without requiring additional dash modifications.
  • Upgrading to component speakers in the dashboard location would be constrained by the 3.5 inch space limitation.
  • The rear deck position typically allows for easier speaker installation access than door-mounted locations.
