Additional Notes
- The 1990 Mitsubishi Eclipse utilizes four distinct speaker locations, each accommodating different size formats and serving specific frequency reproduction roles within the factory audio configuration.
- Dashboard speakers are restricted to 4-inch units designated for midrange frequency reproduction, suggesting these positions handle vocal clarity and mid-frequency content rather than bass or extreme high frequencies.
- Both front and rear door panels accept 6.5-inch speakers, with compatibility extending to either midbass or full-range designs, indicating flexibility in replacement strategy depending on whether a component or coaxial system is preferred.
- The rear side panel positions accommodate 6x9-inch speakers configured as full-range units, which typically offer greater surface area for low-frequency output compared to the round door speakers.
- Replacement priority likely favors the front door 6.5-inch positions when upgrading stereo imaging and midrange fidelity, while the rear 6x9-inch speakers would contribute more substantially to overall bass response and cabin fill.
- Full-range speakers in the door positions would provide self-contained sound reproduction with integrated tweeters, whereas selecting midbass drivers would necessitate reliance on the dashboard midrange units or aftermarket tweeters for high-frequency extension.
- The single DIN radio opening permits straightforward head unit replacement with standard aftermarket receivers, potentially enabling power and signal quality improvements that would benefit any speaker upgrades throughout the system.
- Sound improvement potential varies by location, with front doors offering the most direct soundstage benefits to occupants, while rear positions contribute ambient fill and low-frequency reinforcement in the cabin environment.
