Additional Notes
- The 1993 Audi 90 features three distinct speaker locations with progressively larger drivers, ranging from 4-inch units in the dashboard to 6.5-inch components in the rear deck lid.
- Dashboard speakers in this configuration handle midrange frequencies exclusively, suggesting a multi-way audio architecture that separates frequency reproduction across different mounting points.
- Front door panels accommodate 5.25-inch drivers capable of handling either midbass or full-range duties, offering flexibility in system design depending on whether the dashboard midrange units remain functional.
- The rear deck lid represents the largest speaker real estate at 6.5 inches, potentially providing the most substantial bass extension when paired with appropriate midbass or full-range replacements.
- Replacing the front door speakers may yield the most noticeable audio enhancement, as these locations typically handle the critical midrange and lower frequencies that dominate musical content.
- A full-range approach in the door panels could simplify the system if dashboard speakers are difficult to access or have failed, consolidating frequency reproduction into fewer, more capable drivers.
- The rear deck speakers might contribute to soundstage depth and bass reinforcement, though their effectiveness depends heavily on trunk cavity acoustics and mounting rigidity.
- Aftermarket component speakers in the front doors would likely deliver superior clarity compared to factory coaxial designs, particularly if paired with outboard crossovers and adequate installation damping.
- The single DIN radio slot permits straightforward head unit upgrades without dashboard modification, potentially improving source quality before signal reaches the speakers.
