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.

These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | inside the spare tire well (Bose-equipped trims) |
|---|---|
| Outer bounding box | ~5" speaker dome diameter, ~5-3/16" mounting bracket diameter, 3.5" magnet diameter, 2.5" depth (factory Bose unit's measured dimensions) — WHOLE CARGO AREA, not the spare-well cavity these figures describe: Nissan press kits give cargo dimensions (length x width x height) of 37.0 x 45.0 x 33.7 in (2015) and 37.0 x 43.0 x 33.7 in (2023, 2024) — the width differs between the kits; Nissan does not say where they are measured. The temporary spare (T165/90D18) is listed as stored "Under body". |
| Known obstructions | Cavity is genuinely shaped for a shallow, spare-tire-well-sized unit — do not recommend a standard-depth aftermarket sub here |
| Usable volume estimate | 0.15 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | Boss Bass600, 8" low-profile powered (direct spare-tire-cavity replacement) |
|---|---|
| Box type | sealed (self-contained, factory-cavity-sized) |
| Location | inside spare tire well, zero cargo loss |
| Subwoofers | Rockville spare-tire-sized powered sub, or standalone cargo-area build for more output |
|---|---|
| Box type | sealed |
| Location | spare tire well (space-preserving) or cargo area (standalone) |
Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.
| Factory speaker size | 6.5" front and back — real component design with separate tweeters above the dash, crossover built into the tweeter |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | yes |
| Factory speaker size | 6.5" (same as front) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | yes |
| Tweeter | n/a — tweeter is dash-mounted, front only |
| Factory amp / premium audio | Bose-branded factory system confirmed on equipped trims: genuine OEM part 28170-5AA0A, a self-contained unit with dual 5" speakers + a dedicated 70W amplifier, mounted inside the spare tire well. Nissan press kits: S/SV 6 speakers; SL/Platinum Bose with 11 speakers including a dual-driver subwoofer (2015 kit: "9 speakers, dual subwoofers" / "11 speakers (including dual subwoofers)"; 2023 and 2024 kits: "11 speakers, including dual driver subwoofer"). |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — aftermarket replacements exist that fit the same spare-tire cavity without touching the head unit |
| Head unit | No replacement needed |
FULLY SPECIFIED FACTORY UNIT CONFIRMED: the OEM Bose subwoofer is a genuine self-contained unit, part number 28170-5AA0A, combining two 5" speakers and a dedicated 70W amplifier into a single enclosure that mounts INSIDE the spare tire (not just resting on top) — measured dimensions: ~5" speaker dome diameter, ~5-3/16" mounting bracket, 3.5" magnet diameter, 2.5" depth. When changing a flat, the unit is moved to the lower-left corner of the cargo area, leaning against the driver-side wall, to access the spare tire. Confirmed aftermarket alternatives that fit the same spare-tire cavity: the Boss Bass600 (low-profile 8" powered sub) and Rockville's spare-tire-sized powered subwoofers — both explicitly sized to fit this exact factory cavity.

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.
