Additional Notes
- The 2011 Infiniti G37 contains multiple speaker locations throughout the cabin, with the front door panels accommodating the most variety in terms of size options. The front doors can house 1-inch tweeters, 3.5-inch midrange speakers, and larger 6.5-inch or 6.75-inch midbass or full-range speakers, suggesting a component-style configuration may be possible in these locations.
- Rear audio coverage in the 2011 Infiniti G37 includes 3.5-inch midrange speakers in both the rear door panels and rear side panels, while the rear deck lid offers two size options: 5.25-inch midbass or full-range speakers and 6x9-inch full-range speakers. This configuration indicates the rear soundstage relies on a combination of midrange frequencies from the door and side panels with additional bass response from the deck lid.
- The center dash location contains a 4-inch midrange speaker, which typically handles vocal frequencies and contributes to sound staging in factory audio systems. Component speaker systems with separate tweeters and midrange drivers could potentially improve frequency separation compared to full-range alternatives in locations where both types are compatible.
- The larger 6.5-inch and 6.75-inch speaker positions in the front and rear doors are compatible with both midbass and full-range speaker types, offering flexibility in upgrade paths. Midbass speakers focus on lower-mid frequencies and often pair with separate tweeters, while full-range speakers attempt to reproduce a broader frequency spectrum from a single driver.
- The rear deck lid positions accept either 5.25-inch or 6x9-inch speakers, with the 6x9-inch option classified exclusively as full-range. The oval 6x9-inch format generally provides greater cone area than round 5.25-inch speakers, which may result in increased bass output potential in that location.
- Aftermarket speaker replacements might prioritize the front door panel locations first, given the variety of sizes available and the presence of dedicated tweeter positions. The 1-inch tweeter locations could handle high frequencies while 6.5-inch or 6.75-inch midbass speakers manage the lower-mid frequencies, creating a component setup that typically offers improved sound clarity over factory configurations.
- The radio accepts both single DIN and double DIN head units, providing options for aftermarket receiver upgrades that might include enhanced amplification or signal processing capabilities. Improved source components can work in conjunction with speaker upgrades to enhance overall audio quality throughout the system.
