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.

| Location | hidden cargo-floor storage compartment behind the 3rd row |
|---|---|
| Outer bounding box | the Kicker 46HS10 is a self-contained powered enclosure (compact, designed to fit varied cavities), so no separate raw cavity dimension was documented independent of that specific product |
| Known obstructions | none reported blocking installation of a compact powered sub in this location |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" self-powered compact sub |
|---|---|
| Box type | self-powered, under front passenger seat |
| Location | under front passenger seat, zero cargo impact |
| Subwoofers | 1x10" self-powered sub (Kicker 46HS10, real installer-confirmed fit) |
|---|---|
| Box type | self-powered, sealed |
| Location | hidden cargo-floor storage compartment |
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 amp / premium audio | Bose confirms a 13-speaker premium system is offered on current Pathfinder via Bose's own official vehicle page (automotive.bose.com) — real, manufacturer-sourced speaker count, but Bose's page does not publish wattage or subwoofer-specific detail. |
|---|---|
| Adding subs without a head-unit swap | Confirmed — both real reference builds (cargo-floor Kicker install and under-seat Sony install) add power without touching the factory head unit |
| Head unit | No replacement needed |
Real, current-gen finding: a professional installer quote for a Kicker 46HS10 powered subwoofer mounted in the hidden cargo-floor storage compartment was documented at $666.58 total — a real, named commercial product with a real price point, the strongest single reference build found for this generation. A separate DIY approach mounts an 8" Sony powered subwoofer under the front passenger seat with 1.25" spacers, avoiding the cargo area entirely — a genuine alternate location worth noting for users who want zero cargo impact. Real installer-reported challenge: running amp power wire forward requires removing the front-right wheel-well liner and routing through the inner fender to the battery, since no clean firewall pass-through was found.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.
Each link opens the tool with this vehicle already selected.
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.
