Additional Notes

  • The 1989 Nissan Maxima features front door panel speaker openings sized at 4x6 inches, which accommodate full-range speaker types without requiring separate tweeters or additional components for frequency distribution.
  • Rear deck lid positions accept 6x9 inch speakers, providing a larger cone area compared to the front positions and potentially contributing more bass response in a full-range configuration.
  • Both factory speaker locations are designed for full-range speakers, suggesting the audio system relies on individual speakers to reproduce the entire frequency spectrum rather than separating highs and lows across multiple drivers.
  • The front door panel locations typically benefit most from replacement attention, as door-mounted speakers often handle primary stereo imaging and midrange clarity for front-seat occupants.
  • The 4x6 inch format in the front doors represents a common rectangular speaker size from this era, though aftermarket options in this exact size may be less abundant than standard round configurations.
  • Rear deck lid speakers at 6x9 inches offer more surface area for moving air, which can enhance lower frequency output when upgraded with aftermarket full-range speakers featuring improved magnet structures and cone materials.
  • The single DIN radio opening allows for direct replacement with aftermarket head units without requiring additional mounting adapters or dash modifications beyond standard installation kits.
  • Full-range speaker compatibility in both locations means replacements should incorporate dedicated tweeters or coaxial designs to handle high frequencies that factory speakers may not reproduce effectively.
