Additional Notes
- The factory dashboard speakers in the 1985 Plymouth Gran Fury may benefit from replacement consideration, as 3.5 inch full-range units typically deliver limited frequency response compared to larger formats, though the compact size suits the available mounting depth in dash locations.
- Rear deck lid positions accommodate 6x9 inch full-range speakers, which generally provide broader bass extension and higher output capability than the smaller dashboard units, potentially creating a noticeable imbalance in sound distribution when both original locations remain stock.
- Full-range speaker types eliminate the need for external crossovers in both locations, simplifying installation while attempting to reproduce the entire audio spectrum through single-cone designs, though this approach often compromises frequency separation compared to component systems.
- Sound improvement efforts might prioritize the rear deck position given the larger speaker size capacity, as 6x9 inch units typically move more air and handle greater power than 3.5 inch speakers, though dashboard replacement could enhance vocal clarity and mid-range definition in the listening position.
- The single DIN radio opening in the 1985 Plymouth Gran Fury accepts standard aftermarket head units, which could provide amplification benefits for upgraded speakers in both locations, particularly if the replacement units feature higher sensitivity ratings than original equipment.
- Spatial separation between dashboard and rear deck positions suggests a front-to-rear soundstage rather than front component staging, which may influence listening characteristics depending on seating position and speaker output balance between the two locations.
