Additional Notes

  • The 2002 Infiniti G20 features a three-location speaker configuration with different sizes serving distinct audio functions throughout the cabin.
  • A-pillar mounted tweeters at 1 inch handle high-frequency reproduction, which typically covers the upper vocal range and cymbal detail in the factory sound system.
  • Front door panels accommodate 6.5 inch drivers that can accept either midbass or full-range replacements, giving owners flexibility in component system design.
  • The rear deck lid houses 6x9 inch full-range speakers, a size that traditionally offers extended bass response compared to smaller circular drivers.
  • Upgrading the front door speakers may provide more noticeable sound improvement than replacing rear deck units, since front-stage imaging tends to dominate the listening experience.
  • Component speaker systems could utilize the existing A-pillar tweeter locations paired with upgraded 6.5 inch midbass drivers in the doors for a dedicated two-way front setup.
  • The 6x9 inch rear configuration suggests the factory system likely emphasized fill and ambiance from the rear rather than focused imaging.
  • Radio replacement options include both single DIN and double DIN head units, providing compatibility with most aftermarket receivers available today.
  • Double DIN compatibility opens possibilities for touchscreen navigation and smartphone integration units without dashboard modification.
  • The combination of small A-pillar tweeters with mid-sized door speakers indicates a factory design that separated frequency duties rather than relying solely on full-range drivers at each location.
