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 | driver's side rear, behind the 3rd row |
|---|---|
| Outer bounding box | sized for an 8" driver (factory spec) — full outer box dimensions not independently published |
| Known obstructions | Hybrid-trim battery impact on this location not confirmed — verify case by case before assuming hybrid trims share this geometry |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | OEM-spec 8" replacement in the factory driver's-side-rear location |
|---|---|
| Box type | factory enclosure |
| Location | driver's side rear, behind 3rd row, Bose trims only |
| Subwoofers | Not researched yet (no larger commercial build confirmed for this generation yet) |
|---|---|
| Box type | unconfirmed |
| Location | unconfirmed |
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 12-speaker system confirmed, with named Centerpoint and SurroundStage processing technologies — matches the same Bose technology family already confirmed on other vehicles covered here (e.g. Mazda CX-30's BassMatch/AudioPilot/Centerpoint/SurroundStage), suggesting these are Bose platform-wide processing brands licensed across multiple automakers, not automaker-specific tech. |
|---|---|
| Adding subs without a head-unit swap | Confirmed — a real, detailed community thread ('21+ Sorento - 12-Channel Bose Audio - Figured out') documents the factory 12-channel Bose wiring/integration approach for this generation. |
| Head unit | No replacement needed |
Real, confirmed platform change from the prior 2015-2020 generation (already) to the more car-like MQ4 unibody platform. Real, specific factory subwoofer location and size confirmed: 8" driver, mounted driver's side rear, behind the 3rd row seats — a real, precise location, cross-referenceable against our other 3-row SUVs that use a similar rear-corner placement. Real trim-availability caution: the Bose system is confirmed available on 2021-2023 models and on 2024-2025 non-hybrid trims specifically — hybrid-trim cargo/battery impact on this exact subwoofer location was NOT independently confirmed, flag as not researched rather than assumed safe (matches our standing hybrid-caution discipline).
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.
