Additional Notes
- The 1991 Mazda Protege utilizes 5.25 inch speakers in both front door panels and rear deck lid positions, maintaining consistency across the factory audio system locations.
- Both speaker locations accept either midbass drivers or full-range units, allowing flexibility in component selection based on whether the installation will include separate tweeters or rely on coaxial designs.
- Front door speakers often receive priority during upgrades since they sit closer to listeners and typically provide more direct sound reproduction compared to rear-mounted units.
- Full-range speakers incorporate built-in tweeters within the same frame, offering a simpler replacement solution that maintains coverage across the frequency spectrum without additional components.
- Midbass-specific drivers focus on mid and low frequency reproduction, which would require separate high-frequency units to maintain treble response in the audio system.
- The single DIN radio opening provides standard dimensions for head unit replacement, compatible with most aftermarket receivers without requiring additional mounting adapters or modifications.
- Upgrading speakers while retaining factory power may yield noticeable improvements in clarity and frequency response, though power handling capabilities would remain limited by the head unit's amplifier output.
- Coaxial full-range speakers tend to offer easier installation in factory locations since they replicate the original configuration without requiring crossover mounting or tweeter placement decisions.
