What we researched for this specific generation: where an enclosure actually fits, what the factory speakers are, how the factory audio is wired, and which real builds and commercial products exist for it. Confidence badges say how well each figure is sourced — this is research, not manufacturer spec.
Body styles covered: 4-Door Sedan
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | trunk, rear deck (factory Bose sub location) |
|---|---|
| Outer bounding box | 40"W x 17"H x 29"-37"D (see caveat above about possible figure reuse across generations). |
| Known obstructions | Factory amp on the trunk ceiling. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | keep/upgrade the factory rear-deck 6x9" Bose subs, working around the half-volume bass-trim quirk with an LC2i converter |
|---|---|
| Box type | n/a — factory rear-deck system |
| Location | rear deck |
| Subwoofers | 1x10" or 1x12" powered addition, tapping rear speaker wires via Posi Wire connectors |
|---|---|
| Box type | n/a — powered unit, non-destructive factory-tap wiring |
| Location | trunk |

| Factory amp / premium audio | Bose premium system: a pair of 6x9" subwoofers in the REAR DECK — the SAME rear-deck 6x9" architecture as the older 2000-2008 (5th/6th Gen) Maxima, meaning that design persisted for at least three real generations before the 8th Gen (2016-2023) switched to a dual-9" trunk-mounted design. Specific factory-system quirk: Bose amps/speakers run low wattage but low resistance (ohms), a deliberate pairing; the system TRIMS BASS AT HALF VOLUME to protect the factory speakers — aftermarket converters exist specifically to 'dial in' and maintain a constant signal past that half-volume point, a genuine factory limitation most owners wouldn't otherwise know about. Nissan's own count: 'Bose premium audio system' with '9 speakers, AM/FM/CD6 in-dash CD changer' (2009 and 2013 press kits); the standard 2009 system is '8 speakers and AM/FM/6CD/MP3'. Nissan prints no speaker sizes, wattage or rear-deck subwoofer pair, so the carried-over rear-deck 6x9 story above is owner-reported. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a specifically-recommended named product: the AudioControl LC2i, recommended specifically for adding subs to Bose-equipped Nissans — the same general LC2i-family product already used as a recommendation on our Nissan CR-V-adjacent and other Bose-equipped pages. Specific wiring approach: Posi Wire connectors splice into the existing rear speaker wires WITHOUT cutting them — a clean, reversible tap method. |
| Head unit | No replacement needed |
Specific factory amp location: mounted on the CEILING of the trunk — a genuinely unusual placement worth noting for anyone planning wiring or clearance around a new build. Real trunk dimension cited: 40"W x 17"H x 29"/37"D — the SAME exact figure given for the 8th Gen (2016-2023) Maxima; it may reflect genuine cross-generation continuity in trunk shape or reused/generic retailer figures.

Measure your own vehicle. Trim levels, factory subwoofer options, and mid-generation changes all move these numbers, and a box cut to a researched figure that does not match your truck is wasted wood. Where a badge reads Unconfirmed, treat the value as a starting point for your own measurement, not as an answer.
