Additional Notes

  • The 2009 Mercedes-Benz SL600 front door panels accommodate larger drivers at 6.5 inches, which may handle lower frequencies more effectively than the smaller rear units.
  • Front speakers accept either midbass or full-range configurations, suggesting flexibility in system design depending on whether a separate subwoofer is present.
  • The 3.5 inch rear door speakers are designated specifically for midrange frequencies, indicating a multi-way factory audio architecture.
  • Replacing front door speakers might provide more noticeable sonic impact given their larger cone area and broader frequency response capabilities.
  • The size difference between front and rear locations suggests the factory system likely divided frequency duties across multiple speaker positions.
  • Aftermarket midrange drivers for the rear positions would need to fit within the 3.5 inch mounting constraint while maintaining appropriate frequency overlap with the front drivers.
  • The double DIN radio opening allows for head unit upgrades with expanded features or processing capabilities that could complement speaker replacements.
  • Full-range speakers in the front positions could potentially simplify the audio system if factory crossover networks or amplification are bypassed.
