Additional Notes
- The 1994 Audi S4 features uniform 6.5 inch speaker openings in both front and rear door panels, which may simplify the selection process when upgrading multiple locations simultaneously.
- Door panel speakers in this configuration accept either midbass drivers or full-range speakers, with midbass units typically requiring separate tweeters for high-frequency reproduction while full-range speakers integrate multiple frequency ranges into a single driver.
- Replacing door panel speakers often produces more noticeable improvements in sound quality than dash or rear deck speakers, since door locations typically handle the majority of midrange and bass frequencies that comprise most musical content.
- Midbass speakers generally offer better low-frequency extension and higher power handling compared to full-range alternatives, though they necessitate additional components like tweeters and crossovers for a complete frequency response.
- Full-range speakers provide a simpler installation path with fewer components, though they typically compromise on both bass depth and treble extension compared to component speaker systems.
- The single DIN radio opening suggests aftermarket head unit replacement remains straightforward without requiring additional dash modification or adapter brackets beyond standard mounting kits.
- Speaker mounting depth and magnet clearance against door panel structures can vary, making it advisable to verify physical clearances before purchasing deeper aftermarket drivers with larger motor assemblies.
