Additional Notes
- The 1990 Mercedes-Benz 300TE has factory speaker openings in two locations, with dashboard positions designed for 4 inch midrange drivers and rear deck lid positions accepting 5.25 inch drivers suitable for midbass or full-range applications.
- Dashboard speakers in this application tend to handle midrange frequencies, which suggests the factory configuration may have used a component-style setup rather than relying solely on full-range drivers throughout the cabin.
- Rear deck lid speakers accept both midbass and full-range driver types, offering flexibility in whether to maintain a separated frequency approach or simplify with full-range units depending on the desired audio system complexity.
- The 4 inch dashboard location typically presents mounting depth constraints that could limit driver selection, particularly for aftermarket units with larger magnets or deeper baskets than original equipment.
- Replacing rear deck speakers might produce more noticeable improvements in overall sound quality compared to dashboard units, since the 5.25 inch size generally provides better low-frequency extension and higher power handling capacity.
- The single DIN radio specification indicates a standard head unit form factor, which may influence how replacement speakers integrate with aftermarket receivers if the audio system receives upgrades beyond just driver replacement.
