Additional Notes
- The 1990 Mercedes-Benz 300E features dashboard speakers limited to 4-inch midrange drivers, suggesting these locations may prioritize mid-frequency reproduction over broader sound coverage.
- Rear deck lid positions accommodate 5.25-inch speakers with compatibility for both midbass and full-range drivers, potentially offering flexibility in system configuration.
- The single DIN radio opening indicates an older receiver standard, which may influence available amplification power for replacement speakers.
- Dashboard midrange speakers in the 1990 Mercedes-Benz 300E could benefit from crossover integration when paired with larger rear speakers to prevent overlap in frequency response.
- The combination of 4-inch midrange units up front and 5.25-inch midbass or full-range speakers at the rear suggests a factory system designed with frequency distribution across multiple locations.
- Full-range 5.25-inch speakers installed in the rear deck position might provide broader frequency coverage compared to midbass-specific models, though bass response would still depend on mounting conditions.
- The 4-inch size constraint for dashboard locations may limit low-frequency output from front speakers, placing greater responsibility on rear components for bass reproduction.
