Additional Notes
- The 1978 Plymouth Volare contains two distinct speaker locations with different size specifications, suggesting a two-stage approach when planning replacements based on listening priorities and budget constraints.
- Dashboard positions accommodate 3.5 inch full-range speakers, which typically handle mid-range frequencies and higher tones but may lack the lower frequency response found in larger driver configurations.
- Rear deck lid openings accept 6x9 inch full-range speakers, a size that generally provides broader frequency coverage and increased bass output compared to smaller dashboard units.
- Replacing rear deck speakers first could yield more noticeable improvements in overall sound quality, as the larger cone area typically produces fuller bass response and higher volume levels than compact dashboard speakers.
- Full-range speaker types at both locations indicate these positions were designed for single-driver units rather than component systems with separate tweeters and woofers.
- The 6x9 inch oval format in the 1978 Plymouth Volare provides a larger surface area than round speakers of equivalent width, potentially offering improved low-frequency performance within the space constraints of the rear deck.
- Upgrading both speaker locations would address the complete frequency spectrum more effectively than replacing either position alone, though the rear deck contribution to bass frequencies remains more substantial.
- Single DIN radio sizing offers compatibility with numerous aftermarket head units, which could enhance system performance when paired with upgraded speakers through improved power output and signal processing capabilities.
