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 SUV
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | cargo area (factory) / under back seat, driver's side (aftermarket alternative) |
|---|---|
| Outer bounding box | no precise dimension published for either location |
| Known obstructions | Factory cargo-net chrome tie-down point can be preserved with a properly designed custom box |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | external powered enclosure tapping the factory Bose sub signal |
|---|---|
| Box type | self-powered, keeps factory sub in place |
| Location | cargo area |
| Subwoofers | JL Audio 10TW1 in a custom under-seat box |
|---|---|
| Box type | custom, sealed, under-seat |
| Location | under back seat, driver's side — zero cargo impact |
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" — real, confirmed across all trims (functions as the woofer in the Elite/DSP component set) |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory speaker size | 6.5" — real, confirmed |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter (Elite only) is A-pillar mounted, front only; C-pillar tweeter/mids serve the rear high-frequency role instead |
| Factory amp / premium audio | Bose confirmed on equipped trims, with a factory subwoofer in the cargo area — a real, detailed community thread ('2019 Honda Passport: 10+1 Channels') documents the full factory channel/wiring architecture, one of the more technically thorough single-vehicle threads found in. |
|---|---|
| Adding subs without a head-unit swap | Confirmed two ways — (1) keep the factory sub enabled and add an external powered enclosure tapping its signal for extra bass, or (2) replace it outright with a build like the JL Audio 10TW1 under-seat box. |
| Head unit | No replacement needed |
Entirely missing model until now — Honda's 2-row, more off-road-oriented platform-mate to the Pilot (shares the Pilot's underlying platform, though this specific cross-badge sharing wasn't independently confirmed via a matching part number, unlike the Nissan/Infiniti case found in the same session). Real factory Bose subwoofer confirmed in the cargo area on equipped trims. Real, named aftermarket alternative found: owners replace the factory sub with a JL Audio 10TW1 (shallow-mount driver) in a custom box mounted under the back seat, driver's side — a real, deliberate choice to fully preserve cargo space instead of using the factory cargo-area location. A custom box built this way can also be designed to keep the factory chrome cargo-net tie-down point usable.
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.
