- The 2009 Infiniti M35 audio system utilizes a multi-speaker configuration spanning several locations throughout the cabin, with sizes ranging from 1 inch tweeters to an 8 inch subwoofer position.
- Dedicated 1 inch tweeter locations exist in the front door panels, which typically handle high-frequency reproduction and may be integrated into the factory component speaker setup.
- The center dash and rear deck lid positions both accommodate 3.5 inch full-range speakers, which reproduce a broad spectrum of frequencies despite their compact size.
- Both front and rear door panels feature 6.5 inch speaker openings that can accept either midbass drivers or full-range speakers, offering flexibility in component selection based on whether a separate tweeter will be used.
- The rear deck center position houses an 8 inch subwoofer, suggesting the factory system includes a dedicated low-frequency driver rather than relying solely on door-mounted speakers for bass output.
- Replacing the door panel speakers with quality aftermarket components may yield noticeable improvements in clarity and tonal balance, particularly if the factory speakers have degraded over time.
- Component speaker systems with separate tweeters and midbass drivers could leverage the existing 1 inch and 6.5 inch locations in the front doors, potentially preserving the factory crossover points or allowing for aftermarket crossover integration.
- The presence of multiple small full-range speakers in the dash and rear deck suggests these positions contribute to overall sound staging and fill rather than primary frequency reproduction.
