Additional Notes
- The 1990 Mazda Protege utilizes 5.25 inch speaker openings in both front door panels and rear deck lid locations, which suggests a uniform approach to the factory audio configuration across both axles.
- Both speaker positions accept either midbass or full-range driver types, indicating that the factory mounting points can accommodate different audio system design philosophies depending on whether a separate tweeter component is incorporated.
- Full-range speakers would handle the entire frequency spectrum in a simpler installation scenario, while midbass drivers would typically require supplementary tweeters for higher frequency reproduction in a component speaker arrangement.
- The front door panel location tends to be prioritized for speaker replacement due to its proximity to the listening position, which can result in more direct sound staging and imaging compared to rear-mounted drivers.
- The rear deck lid placement may be influenced by trunk space limitations and the need to project sound forward into the cabin, though this configuration can sometimes create a less focused soundstage than front-biased systems.
- Aftermarket 5.25 inch speakers are widely available across various power handling and sensitivity ratings, which provides flexibility in matching replacement drivers to the capabilities of the stock or upgraded head unit in the 1990 Mazda Protege.
- The single DIN radio opening follows the standard dimensions that were prevalent during this manufacturing period, allowing for straightforward replacement with period-correct or modern single DIN aftermarket receivers.
