- The 1990 Plymouth Colt features three distinct speaker locations with varying sizes, suggesting a distributed audio system design where the dashboard position accepts 4-inch midrange drivers while the doors and rear deck accommodate larger diameter speakers for extended frequency response.
- Dashboard speakers in this configuration are limited to midrange-only applications, which indicates they likely handle vocal frequencies and mid-frequency content rather than bass reproduction, potentially requiring careful crossover integration with the larger door and rear speakers.
- Front door panels accept 6.75-inch speakers designated for either midbass or full-range use, offering flexibility in system configuration where installers could choose dedicated midbass drivers for a component setup or full-range coaxial speakers for a simpler replacement approach.
- The rear deck lid location accommodates 5.25-inch speakers with midbass or full-range compatibility, providing a smaller form factor than the front doors while still maintaining lower frequency capabilities that the dashboard position cannot support.
- Replacing the front door speakers might take priority given their larger size and dual-purpose capability, as 6.75-inch drivers typically provide better bass response and sensitivity compared to the smaller 5.25-inch rear deck and 4-inch dashboard positions.
- The 1990 Plymouth Colt's speaker arrangement separates frequency duties by physical location, with the dashboard handling midrange content while doors and rear deck manage fuller frequency ranges, which could affect staging and tonal balance when selecting replacement speakers.
- Midbass-capable speakers in the door and rear positions would extend lower frequency response beyond what midrange-only dashboard units can produce, potentially reducing reliance on subwoofer supplementation for listeners seeking improved bass output without adding amplification.
- The 4-inch dashboard speakers present size constraints that limit power handling and excursion capabilities, which may result in this position contributing less overall output to the system compared to the larger door-mounted drivers.
- Full-range speaker options for both 6.75-inch and 5.25-inch locations would include integrated tweeters for high-frequency reproduction, whereas midbass-specific drivers would require separate tweeters to maintain treble response if dashboard midrange speakers are insufficient for upper frequencies.
- Sound improvement potential varies by location, with door speakers offering the greatest impact due to their size advantage and proximity to front-seat occupants, while rear deck speakers contribute ambient fill and rear-passenger coverage in the cabin environment.
