Additional Notes

  • The dashboard location in the 1977 Plymouth Volare accommodates a relatively compact 3.5 inch full-range speaker, which suggests this position may be secondary in the factory audio configuration when compared to the larger rear deck opening that measures 6x9 inches.
  • Full-range speakers are designated as compatible for both dashboard and rear deck positions, indicating that separate tweeters or dedicated midrange components would not typically be necessary for a straightforward replacement approach in this application.
  • The rear deck lid location tends to be the primary sound source in many vehicles from this era, and the 6x9 inch opening provides substantially more surface area than the dashboard position, which could influence the overall sound output and frequency response when upgrading either location.
  • When considering speaker replacement in a 1977 Plymouth Volare, the rear deck position might receive priority due to the larger size allocation, though the dashboard location could contribute to improved staging and higher frequency dispersion toward front passengers.
  • The single DIN radio specification indicates a standard head unit opening that aligns with the period during which this vehicle was manufactured, and aftermarket head units with enhanced power output or equalization features would physically integrate without modification to the dash panel.
  • Component speakers with separate crossovers might pose installation challenges given the full-range designation for both locations, though the 6x9 inch rear opening could theoretically accommodate coaxial designs that incorporate integrated tweeters within the same mounting footprint.
