Additional Notes

  • The 2001 Acura CL features a three-way speaker configuration with A-pillar tweeters, front door panel midbass or full-range drivers, and rear deck full-range speakers.
  • The A-pillar tweeters measure 1 inch and handle high-frequency reproduction, while the front door panels accommodate 6.5 inch drivers that can serve as dedicated midbass units in a component system or standalone full-range speakers.
  • Rear deck lid locations accept 6x9 inch full-range speakers, which typically provide broader frequency coverage than the smaller door speakers due to their larger surface area.
  • The factory configuration suggests a front-biased sound stage with the combination of separated high-frequency drivers and larger midbass units in the doors.
  • Replacing the front door speakers may offer more noticeable improvement than rear deck upgrades since the front speakers handle the majority of staging and imaging responsibilities.
  • Component speaker systems would utilize the existing A-pillar tweeter locations while replacing the door speakers with dedicated midbass drivers and external crossover networks.
  • Full-range speakers installed in the front doors would eliminate the need for the A-pillar tweeters, though this might reduce high-frequency extension compared to a proper component setup.
  • The 6x9 inch rear speakers could contribute to overall system fullness and bass response when properly integrated with the front stage.
  • Single DIN or Double DIN aftermarket head units can be installed, providing flexibility for integrating modern source units with improved amplification and signal processing capabilities.
