Additional Notes

  • The 1990 Mazda MX-6 factory audio configuration includes dashboard speakers that accommodate 5.25 inch full-range replacements, while the rear deck lid positions accept larger 6.5 inch units compatible with either midbass or full-range applications.
  • Dashboard locations are limited to full-range speaker designs due to the 5.25 inch mounting constraint, which influences available frequency response capabilities in the front soundstage.
  • Rear deck lid positions offer flexibility between dedicated midbass drivers and full-range speakers, allowing different approaches to system tuning based on whether front speakers handle higher frequencies independently.
  • The size differential between front and rear positions creates potential for varied staging strategies, with smaller dashboard units handling imaging duties while larger rear speakers contribute additional lower frequency output.
  • Single DIN radio compatibility provides standard aftermarket head unit options without requiring modifications to the center console mounting area.
  • Full-range speakers in dashboard positions would need to reproduce the complete frequency spectrum from a smaller cone area compared to the rear deck locations.
  • The 6.5 inch rear specification enables deeper bass extension compared to dashboard speakers when using midbass-focused drivers with appropriate crossover points.
  • Choosing midbass drivers for rear positions would typically require component speakers or coaxial units in the dashboard to maintain high frequency reproduction throughout the cabin.
