Additional Notes
- The 1987 Plymouth Reliant appears to have factory speaker locations in two areas: dashboard-mounted positions and rear deck lid positions, each requiring different full-range speaker types.
- Dashboard speaker positions accommodate 3.5-inch full-range speakers, which typically offer limited bass response due to their smaller cone area but can provide adequate mid-range and high-frequency reproduction in close listening positions.
- Rear deck lid positions accept 5x7-inch full-range speakers, providing a larger radiating surface compared to the dashboard units, which may contribute to improved lower frequency output and overall volume capability.
- The size difference between front and rear speakers suggests that replacing rear deck speakers might yield more noticeable sound quality improvements, particularly in bass extension and overall output levels.
- Full-range speakers in these applications handle the entire frequency spectrum through a single driver, eliminating the need for separate tweeters or crossover networks in the factory configuration.
- The single DIN radio opening indicates standard head unit replacement options would be available without requiring custom mounting solutions or dashboard modifications.
- Both speaker locations utilize full-range designs rather than component systems, suggesting a factory audio approach prioritizing simplicity and cost-effectiveness over audiophile-grade sound staging.
- The 5x7-inch format in the rear deck represents a common speaker size from that era, offering reasonable bass response while fitting within typical deck lid mounting constraints.
