Additional Notes
- The 1984 Plymouth Horizon front door panels accommodate 5.25-inch speakers that can function as either midbass drivers or full-range units, suggesting flexibility in component selection based on whether a separate tweeter will be installed.
- Rear door panels support 6x9-inch full-range speakers, which typically provide broader frequency response compared to the smaller front speakers due to their larger surface area and oval configuration.
- The difference in speaker sizing between front and rear locations indicates that factory audio distribution likely relied on the larger rear speakers to reproduce lower frequencies while smaller front units handled mid-range content.
- Full-range compatibility in both positions means aftermarket speakers designed to reproduce the entire audio spectrum without supplementary tweeters could be installed throughout the vehicle.
- The 5.25-inch front position could support a component speaker system where dedicated midbass drivers handle frequencies below the crossover point while tweeters mounted separately manage higher frequencies.
- Single DIN radio mounting suggests integration with aftermarket head units follows a standardized opening, though deck selection would need to account for potential depth constraints behind the dashboard.
- Sound quality improvements would likely be most noticeable when replacing rear speakers first, given their larger cone area and typical role in bass reproduction within the stock configuration.
