Additional Notes
- The 1979 Dodge St. Regis front speakers measure 3.5 inches, placing them among the smaller factory installations of the era, which could limit output capability compared to the larger rear units.
- Both dashboard and rear positions utilize full-range speaker types, suggesting the factory audio design relied on single-driver solutions rather than component configurations with separate tweeters and woofers.
- Replacing the dashboard speakers might prove challenging given the 3.5-inch size constraint, as this format typically offers less cone area for bass response compared to more common 4-inch or larger replacements.
- The rear speakers at 6x9 inches provide substantially more surface area than the front units, potentially making them the primary focus for sound quality improvements when considering upgrade options.
- Full-range speakers in both positions would handle all frequencies from a single driver, though aftermarket component speakers could provide separation of high and low frequencies if mounting depth and space allow modifications.
- The 6x9 format in the rear deck of the 1979 Dodge St. Regis represents a common domestic automotive speaker size from this period, which continues to have broad aftermarket support.
- Single DIN radio compatibility indicates standard depth and width constraints for head unit replacement, though this specification doesn't directly affect speaker choices beyond potential power output considerations from upgraded source units.
- The size disparity between front and rear speakers could create an unbalanced soundstage, with rear speakers potentially overpowering the smaller dashboard units unless power distribution or fader settings compensate for the difference.
