Additional Notes

  • The 2009 Infiniti EX35 factory audio system incorporates a dedicated tweeter arrangement with 1-inch units mounted in the dashboard locations, which typically handle the upper frequency spectrum separately from the larger door-mounted speakers.
  • Front and rear door panels share the same 6.5-inch speaker size, accepting either midbass or full-range replacements depending on whether the factory crossover network is retained or bypassed during aftermarket installation.
  • The cargo area features a 5.25-inch speaker location that provides additional audio coverage for rear passengers and can accommodate either midbass or full-range units based on system configuration preferences.
  • Upgrading the door panel speakers may offer the most noticeable sound quality improvement since these 6.5-inch locations handle the majority of the audible frequency range in most factory configurations.
  • The separate tweeter system suggests the factory setup likely includes passive crossovers that divide frequencies between the dashboard tweeters and door-mounted midbass drivers, which should be considered when selecting replacement components.
  • Component speaker systems designed for 6.5-inch applications would allow replacement of both the door midbass drivers and dashboard tweeters with matched aftermarket units, potentially providing better frequency integration than mixing factory and aftermarket pieces.
  • The cargo area speaker location may function primarily as rear fill in the factory configuration, contributing ambient sound rather than primary stereo imaging for front-seat occupants.
