Additional Notes
- The 1987 Audi 4000 features three distinct speaker locations with different sizes, suggesting that replacing all factory speakers could provide a more balanced soundstage improvement compared to upgrading only one position.
- The dashboard location houses 4 inch midrange drivers, which typically handle vocal frequencies and middle-range instrumentation. Aftermarket midrange speakers in this position may enhance clarity in spoken audio and lead guitar tones.
- Both the front door panels and rear deck lid accommodate 5.25 inch speakers, allowing for consistency in component selection between front and rear positions if desired.
- The front door panel speakers accept either midbass or full-range types, giving options between dedicated low-frequency reproduction or complete frequency coverage from a single driver.
- Midbass speakers in the door panels would likely complement the dashboard midrange units by handling lower frequencies, potentially creating a more separated and detailed frequency response.
- Full-range speakers in the door positions could function independently of the dashboard speakers, which might be preferable if only upgrading select locations rather than the complete system.
- The rear deck lid speakers share the same midbass and full-range compatibility as the front doors, suggesting they could serve as either rear fill for ambiance or additional bass reinforcement depending on the chosen speaker type.
- The single DIN radio opening indicates that head unit upgrades would need to match this standard size, though adapters could potentially accommodate different formats if desired.
- Replacing the smaller 4 inch dashboard speakers may prove more challenging to find high-quality aftermarket options compared to the more common 5.25 inch size used in the other positions.
