Additional Notes
- The 1981 Plymouth Gran Fury dashboard speakers may present a challenge for replacement due to their 3.5-inch sizing, which represents a relatively uncommon specification in contemporary aftermarket catalogs. Full-range drivers in this size typically offer limited low-frequency extension, suggesting that rear deck upgrades might produce more noticeable acoustic improvements.
- The rear deck lid location accommodates 6x9-inch full-range speakers, which generally provide broader frequency response capabilities compared to smaller dashboard units. This mounting position often benefits from the trunk cavity's acoustic properties, potentially enhancing bass output without requiring separate subwoofer installation.
- The single DIN radio opening follows standardized dimensioning that permits straightforward head unit upgrades. Replacement receivers with higher preamp voltage outputs could drive aftermarket speakers more effectively than the factory electronics likely would have.
- Full-range speakers in the 6x9-inch configuration typically incorporate multiple driver elements or whizzer cones to extend high-frequency response. This design approach may offer improved tonal balance over the dashboard speakers when reproducing mixed audio content.
- Prioritizing rear deck speaker replacement in the 1981 Plymouth Gran Fury might yield more substantial sound quality gains due to the larger cone area and potentially superior mounting depth available at that location. Dashboard speaker upgrades could follow as a secondary consideration if further refinement is desired.
- The specified speaker locations suggest a two-position audio system layout common to period vehicles. Contemporary installations sometimes incorporate component speaker systems in these positions, though depth clearance and mounting provisions would require verification before such modifications.
