Additional Notes
- The 1985 Plymouth Reliant appears to prioritize rear deck lid speaker replacement when upgrading the audio system, as the 5x7 inch openings provide greater surface area for sound reproduction compared to the 3.5 inch dashboard locations.
- Full-range speakers represent the compatible type across both mounting positions, suggesting a two-way design incorporating woofer and tweeter elements within single speaker assemblies rather than requiring separate component installations.
- The dashboard positions accept 3.5 inch full-range speakers, which typically handle midrange and higher frequencies with reasonable clarity given their size constraints in instrument panel installations.
- Rear deck lid locations accommodate 5x7 inch speakers, a size that potentially delivers improved bass response and overall output compared to smaller dashboard units due to the increased cone area available for air displacement.
- The single DIN radio specification indicates a standard 2-inch tall head unit opening, which may limit modern aftermarket receiver options compared to double DIN configurations but maintains compatibility with most basic replacement units.
- Sound improvement in the 1985 Plymouth Reliant would likely come from replacing factory speakers with aftermarket full-range models featuring higher sensitivity ratings and improved frequency response characteristics within the existing size constraints.
- The 5x7 inch size represents a somewhat uncommon footprint in contemporary speaker manufacturing, though many 6x8 inch speakers include adapter brackets to fit these openings without modification to the vehicle.
- Both speaker positions utilize full-range designs rather than component separates, suggesting a simpler wiring configuration with direct connections from the head unit to individual speakers without external crossover networks.
