Additional Notes

  • The 2013 Infiniti FX37 contains five distinct speaker locations spread throughout the cabin and cargo area, with sizes ranging from 3.5 to 6.5 inches depending on placement and acoustic function.
  • Door panel speakers in both front and rear positions utilize 6.5 inch drivers, which typically handle a broader frequency range compared to the smaller dashboard units and may benefit from aftermarket upgrades focused on midrange clarity and bass response.
  • Both center dash and standard dashboard positions feature 3.5 inch full-range speakers, which generally prioritize higher frequency reproduction and vocal clarity within the limited space constraints of upper cabin mounting locations.
  • The cargo area houses a 5.25 inch speaker that accepts either midbass or full-range configurations, suggesting this location could serve supplementary low-frequency reinforcement or ambient sound fill depending on the factory audio system configuration.
  • Midbass-capable speakers in the 2013 Infiniti FX37 door and cargo positions may provide noticeable tonal depth improvements when replaced with aftermarket units featuring enhanced cone materials or higher power handling specifications.
  • The single DIN radio chassis potentially limits integration options for modern multimedia receivers, though adapters and installation kits may accommodate upgraded head units while maintaining speaker system compatibility.
  • Full-range speaker compatibility across all locations suggests the factory system likely operates without dedicated tweeters in some positions, meaning aftermarket component speaker systems with separate high-frequency drivers could expand soundstage width and imaging precision.
