Additional Notes
- The rear deck lid positions in the 1989 Honda Prelude accommodate 5.25-inch speakers, which might be considered a priority replacement area given the typical degradation of factory rear speakers over time in vehicles of this era.
- Front door panels accept 6.5-inch speakers, offering a larger cone area compared to the rear locations, which generally translates to greater potential for bass response and overall sound pressure levels.
- Both locations support either midbass or full-range speaker types, providing flexibility in system design depending on whether a separate tweeter configuration is planned or a simpler full-range solution is preferred.
- The difference in speaker sizes between front and rear locations suggests that the 1989 Honda Prelude's factory audio design allocated larger drivers to the front doors, likely to emphasize frontstage imaging.
- Midbass speakers in these positions would typically handle frequencies from approximately 80-100 Hz up to 2-4 kHz, requiring additional tweeters for high-frequency reproduction, while full-range options would attempt to cover the entire audible spectrum from a single driver.
- The radio opening supports both single DIN and double DIN head units, which may influence speaker selection if upgrading to a modern receiver with built-in amplification or advanced crossover capabilities.
- Aftermarket speakers in the 6.5-inch front locations would likely produce more noticeable sound quality improvements than rear replacements due to their proximity to front-seat occupants and larger radiating surface area.
- Component speaker systems with separate woofers and tweeters could be installed in the front doors, though this would require identifying or creating suitable mounting locations for the tweeter elements beyond the specified 6.5-inch opening.
