Additional Notes
- The dashboard speakers in the 1984 Plymouth Reliant are likely candidates for replacement given their modest 3.5 inch size, which tends to offer limited acoustic output compared to larger drivers that could potentially fit in modified installations.
- Full-range speaker types are specified for both locations, suggesting a system design that relies on individual drivers to reproduce the entire frequency spectrum rather than separating bass and treble duties across multiple components.
- The rear deck lid accommodates 5x7 inch speakers, which provide considerably more cone area than the front units and may serve as the primary sound source for lower frequencies in this configuration.
- Sound improvement would likely come from replacing aging original speakers with contemporary full-range units that feature updated materials like polypropylene cones, rubber surrounds, and stronger magnets compared to what was typical in mid-1980s factory installations.
- The single DIN radio opening permits straightforward head unit upgrades without requiring dash modifications, which could provide signal processing improvements like equalization and higher pre-amp voltage to drive aftermarket speakers more effectively.
- The size disparity between front and rear speakers may result in an unbalanced soundstage, with rear-biased output that could be addressed through amplifier fading or by installing higher-sensitivity drivers in the dashboard positions.
