Nissan Quest Rear Speaker Size
The Nissan Quest rear location accommodates a 2 inch speaker size, as well as 3.5 inch, 4 inch, and 6x8 inch speakers across the model's production range. Compatible audio types for these units include tweeters, midrange, and full-range system configurations. These specifications cover the years 1993 through 2009.

| 2007 | Tweeter | 2 |
| 2006 | Midrange | 3.5 |
| 2005 | Midrange | 3.5 |
| 2004 | Midrange | 3.5 |
| 1999 | Midrange | 4 |
| 1999 | Full-Range | 6x8 |
| 1998 | Full-Range | 6x8 |
| 1997 | Full-Range | 6x8 |
| 1996 | Full-Range | 6x8 |
| 1995 | Full-Range | 6x8 |
| 1994 | Full-Range | 6x8 |
| 1993 | Full-Range | 6x8 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 rear speaker location in the Nissan Quest spans multiple distinct mounting formats across the production range, with oval and circular cutout geometries both represented depending on the model year.
- A 6x8 inch oval driver occupies a larger baffle area than a circular speaker of equivalent nominal diameter, allowing for greater cone surface area within the depth-constrained rear panels typical of minivan body construction.
- Full-range speakers, as found in the 6x8 inch rear positions, are designed to reproduce low, mid, and high frequencies from a single driver, making the mounting location the sole source of broadband audio output in that zone without reliance on a supplementary crossover network.
- The 4 inch circular driver listed for the 1999 Nissan Quest rear position operates alongside a 6x8 inch full-range unit, indicating the rear panel contains 2 separate mounting cutouts of different sizes in that model year.
- A 4 inch midrange driver handles the middle portion of the audible frequency spectrum, roughly between 300 Hz and 5 kHz, and in a rear cabin location serves primarily to reinforce vocal and instrumental presence for rear-seat passengers.
- The 3.5 inch midrange format listed for the 2004 through 2006 models occupies a relatively compact circular cutout, consistent with shallow rear-panel cavities or pillar-mounted positions where available depth and diameter are limited.
- A 3.5 inch midrange driver, being smaller than a 4 inch unit, produces a narrower low-frequency extension, concentrating output in the mid-frequency range rather than contributing to bass reproduction in the rear cabin.
- The 2 inch tweeter format listed for the 2007 through 2009 Nissan Quest rear location indicates the mounting position accommodates only a high-frequency driver, as tweeters are designed to reproduce frequencies typically above 2 kHz and require a very small cutout diameter.
- A tweeter placed in the rear of a minivan cabin contributes high-frequency dispersion toward rear-seat occupants, a position that affects the spatial balance of treble energy relative to the front soundstage.
- The transition from full-range 6x8 inch drivers in the earlier production years to progressively smaller dedicated-frequency drivers in later years reflects a shift in rear mounting cavity dimensions across the Quest's generational redesigns.
- Because tweeters lack low- and mid-frequency output by design, the 2 inch rear driver in the 2007 to 2009 models does not function as a standalone audio source and is acoustically dependent on front or supplementary drivers to cover the rest of the frequency spectrum.
