Additional Notes

  • The 1990 Acura Legend features three distinct speaker locations with two different size configurations spread across the front and rear positions.
  • Both front door panel and rear deck lid positions accept 6.5 inch speakers, offering flexibility in component selection for those locations.
  • The rear deck lid contains two separate speaker positions, with one accommodating 6.5 inch units and another designed for 6x9 inch speakers.
  • Midbass or full-range speakers can be installed in the front door panels, while the rear 6.5 inch location supports the same compatibility range.
  • The 6x9 inch rear deck position is specified exclusively for full-range speakers, which typically handle a broader frequency spectrum without requiring additional tweeters.
  • Replacing factory speakers in the rear deck with aftermarket 6x9 inch full-range units may provide enhanced bass response and overall volume capability due to the larger cone area.
  • The front door positions might represent the primary stereo imaging locations, making component speaker systems with separate tweeters a consideration for improved high-frequency clarity.
  • Full-range speakers in the 6.5 inch size offer integrated tweeter designs that simplify installation compared to component systems requiring separate mounting points.
  • The dual rear deck configuration suggests a potential strategy of mixing speaker types, though matching impedance and sensitivity ratings across all positions would maintain balanced output levels.
  • Radio replacement options include both single DIN and double DIN head units, providing compatibility with contemporary touchscreen and advanced connectivity systems.
