Additional Notes
- The factory audio system in the 1999 Acura CL utilizes a three-position speaker configuration with tweeters mounted in the A-pillars and larger drivers in both the front doors and rear deck.
- The A-pillar tweeters handle high-frequency reproduction exclusively, while the front door panels accommodate either dedicated midbass drivers or full-range speakers depending on whether a component or coaxial approach is preferred.
- Rear deck speakers use an oval 6x9 inch format rather than round drivers, which typically provides greater cone area within the available mounting space.
- Replacing the front door speakers may offer the most noticeable improvement in overall sound quality, as these locations handle the critical midrange frequencies and often benefit from aftermarket units with stronger magnetic structures and more rigid cone materials.
- The dual DIN radio compatibility suggests flexibility for head unit upgrades, though this may influence which speaker replacements would be most appropriate based on the available power output and crossover settings.
- Full-range speakers in the rear deck position would reproduce all frequencies independently, while the front locations could utilize component sets with the existing A-pillar tweeters potentially being replaced to match.
- The 6.5 inch front door format represents a common size that tends to have extensive aftermarket availability across various performance and price tiers.
