Nissan 350Z Rear Speaker Size
The Nissan 350Z rear location accommodates a 6.5 inch speaker size and 10 inch units. Compatible audio types for the rear include subwoofers and midbass or full-range system speakers. These specifications cover the 2003 to 2009 model range.
| Year | Type | Size (inch) |

| 2009 | Subwoofer | 10 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Subwoofer | 10 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Subwoofer | 10 |
| 2007 | Midbass / Full-Range | 6.5 |
| 2006 | Subwoofer | 10 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Subwoofer | 10 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Subwoofer | 10 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Subwoofer | 10 |
| 2003 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The Nissan 350Z rear speaker location accommodates 2 distinct speaker sizes simultaneously: a 10 inch position and a 6.5 inch position, indicating the rear of the cabin is engineered to house more than one driver type within the same zone.
- A 10 inch subwoofer in the rear of the Nissan 350Z occupies a relatively large mounting footprint, requiring sufficient enclosure depth or cavity volume behind the mounting surface to allow adequate cone excursion for low-frequency reproduction.
- Subwoofers are dedicated low-frequency transducers, typically operating in the range below 80 to 150 Hz, and a 10 inch cone diameter produces the displacement necessary to move enough air for bass output in an enclosed cabin environment.
- The rear placement of a 10 inch subwoofer in a compact sports car like the 350Z takes advantage of the fact that low-frequency sound waves are largely omnidirectional, meaning the listening position relative to the driver has minimal effect on perceived bass directionality.
- The 6.5 inch mounting location in the rear of the 350Z is sized for a mid-range driver, a diameter commonly associated with frequency handling from approximately 60 Hz up to 5 kHz depending on cone material and crossover configuration.
- A midbass driver at the 6.5 inch position handles the lower-mid portion of the audible spectrum, roughly 80 Hz to 500 Hz, reinforcing male vocals, bass guitar fundamentals, and kick drum body within the rear soundstage of the cabin.
- A full-range driver at the 6.5 inch position covers a wider portion of the spectrum than a dedicated midbass unit, typically spanning from around 60 Hz to 20 kHz, allowing a single driver to handle midrange and high-frequency content without a separate tweeter.
- The compatibility of both midbass and full-range types with the 6.5 inch rear location in the 350Z indicates the mounting cavity dimensions are consistent enough across both driver classifications to seat either type without structural modification.
- In a rear-mounted configuration within a sports coupe, 6.5 inch drivers at or near the rear deck or interior panel contribute to fill and ambience rather than primary imaging, as the primary listening axis of seated occupants faces forward.
- The rear location of the 350Z supports the pairing of a subwoofer with a midbass or full-range driver, a configuration where the 10 inch unit handles deep bass reproduction and the 6.5 inch unit manages the frequencies above the subwoofer's upper crossover point.
