Additional Notes
- The 2012 Infiniti G37 features a multi-speaker configuration with varying sizes distributed across different locations, suggesting a factory audio system designed with component-style separation where tweeters, midrange drivers, and midbass speakers handle distinct frequency ranges rather than relying solely on full-range units.
- Front door panels accommodate multiple speaker sizes including 1 inch tweeters, 3.5 inch midrange drivers, and both 6.5 inch and 6.75 inch midbass or full-range speakers, indicating overlapping size compatibility that may require verification of specific mounting locations and depth clearances before replacement.
- The presence of dedicated 1 inch tweeter locations in the front doors suggests that upgrading these high-frequency drivers could noticeably affect clarity and detail in vocals and upper-range instruments, particularly since tweeters typically handle frequencies above 3-4 kHz where human hearing is most sensitive.
- Rear audio coverage includes 3.5 inch midrange speakers in both the rear door panels and rear side panels, along with 6.5 inch midbass or full-range speakers in the rear doors, creating redundancy that may allow for selective upgrading based on listening priorities and budget constraints.
- The rear deck lid offers two size options with 5.25 inch midbass or full-range speakers and 6x9 inch full-range speakers, where the oval 6x9 format typically provides greater cone area for bass response compared to round 5.25 inch drivers, though installation compatibility would depend on factory mounting configurations.
- A 4 inch midrange speaker located in the center dash likely serves to anchor front soundstage imaging and dialogue clarity, positioning that makes it potentially influential for perceived audio quality despite its relatively small size compared to door-mounted drivers.
- The 2012 Infiniti G37 radio opening accepts both single DIN and double DIN head units, providing flexibility for aftermarket stereo upgrades that could include enhanced amplification, digital signal processing, or connectivity features to complement speaker replacements.
- Upgrading the 6.5 inch or 6.75 inch midbass speakers in the front doors would likely yield the most substantial sound improvement, as these larger drivers handle critical midrange and upper bass frequencies while also contributing significantly to overall volume output and dynamic range.
- The availability of both midbass and full-range speaker types across multiple locations suggests that some positions may be intended for use with external amplification and crossovers in a component system, while others might function adequately with coaxial full-range designs powered by head unit amplification.
- Replacing the 3.5 inch midrange speakers throughout the cabin could improve vocal reproduction and midrange definition, though their smaller size inherently limits low-frequency extension and power handling compared to the larger door and deck-mounted drivers.
