Additional Notes
- The dashboard locations in the 1989 Plymouth Reliant accommodate 3.5 inch full-range speakers, which typically serve as the primary source for mid-range and higher frequencies in the cabin. These smaller apertures generally limit bass output but can provide clarity for vocal reproduction and instrument detail when replaced with quality aftermarket units.
- The rear deck lid positions accept 5x7 inch full-range speakers, offering a larger cone area than the dashboard units. This oval format may contribute to improved low-frequency response compared to the front locations, though the specific acoustic properties depend on the mounting depth and enclosure characteristics of the deck lid structure.
- Full-range speaker compatibility across both locations suggests the factory design relied on single-driver solutions rather than component systems with separate tweeters and woofers. Aftermarket replacements maintaining the full-range configuration could simplify installation while potentially offering improvements in sensitivity, power handling, and frequency extension over original equipment.
- The single DIN radio specification indicates a standard height opening that accepts most aftermarket head units without modification. This configuration may allow for integration of modern source units with enhanced amplifier output, which could better drive replacement speakers in both the 1989 Plymouth Reliant dashboard and rear deck positions.
- Prioritization of speaker replacement might reasonably focus on the rear deck locations first, given their larger size and potential for greater sonic impact. However, the dashboard speakers contribute significantly to stereo imaging and frontal staging, so balanced upgrading of both positions would likely yield more cohesive audio improvement than addressing either location independently.
