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, 3-row
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | side-firing, flush against cargo area side panel, behind 3rd row |
|---|---|
| Outer bounding box | Cargo behind 3rd row (seat up): ~18" depth at bottom, ~14" at top, ~12" height |
| Known obstructions | Must allow reaching UNDER the subwoofer to access the spare tire release — a real usability constraint, not just a volume figure |
| Usable volume estimate | 1.5 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" small sealed |
|---|---|
| Box type | sealed |
| Location | side-firing, cargo area |
| Subwoofers | 1x10" sealed, side-firing (real example: Skar VS-10 D2 pre-loaded) |
|---|---|
| Box type | sealed |
| Location | flush against cargo side panel — keep spare tire release accessible |
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" |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | 6.5" (same as front) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter (Elite only) is dash/A-pillar mounted, not door-mounted |
| Factory amp / premium audio | Real, and a genuine contrast worth flagging against our other Honda entries. UNLIKE the Civic Hatchback and CR-V (which use Honda's own unbranded 'Premium Audio System'), the Pilot DOES use Bose — confirmed standard on Touring trim and above for 2022, with the top Elite trim specifically getting 590W across 10 speakers. Honda's audio branding is not consistent across its own lineup; don't assume one Honda model's finding applies to another. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — the side-firing product avoids the head unit entirely |
| Head unit | No replacement needed |
Cargo behind 3rd row (seat up): ~18" depth at the bottom, ~14" at the top, roughly 12" height. Skar Audio's side-firing enclosure is precision-molded to sit flush against the side panel with a pre-mounted 10" VS-10 D2, pre-wired to 1-ohm final impedance — a genuinely space-efficient, purpose-built design. REAL PRACTICAL ACCESS NOTE: whatever gets installed needs to allow reaching UNDER the subwoofer to access the spare tire release — a real usability constraint distinct from pure volume/dimension specs, similar in spirit to other access-constraint findings.
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.
