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 | tire jack storage compartment (down-firing) or behind 3rd row |
|---|---|
| Outer bounding box | Down-firing clearance genuinely tight: only ~1" floor clearance at the rear, ~2" at the front closest to the rear seats |
| Known obstructions | Must use quick-disconnect mounting — owners actively use this cargo space for hauling, not a fixed installation |
| Usable volume estimate | 0.5 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 2x8" sealed, tire jack compartment |
|---|---|
| Box type | sealed |
| Location | tire jack storage compartment |
| Subwoofers | 1x10" HO/low-profile (e.g. JL W3v3), behind 3rd row |
|---|---|
| Box type | sealed |
| Location | behind 3rd row seating — must be quick-disconnect for cargo access |
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" (raised surround mounting configuration) |
|---|---|
| Known obstructions | Genuine OEM front door speaker part exists (left/right specific), confirming this is a known factory location |
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar-mounted (standard 1" size) on premium/equipped trims — real, confirmed. Real, important safety caution: a side airbag runs through the A-pillar on most vehicles including this one — treat any A-pillar tweeter work as airbag-adjacent, not a simple trim-panel job. |
| Factory speaker size | unconfirmed |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is A-pillar mounted, front only |
| Factory amp / premium audio | Real, partial — confirmed for the tail end of this generation only. Harman Kardon premium sound confirmed on 2019-2020 Sorento (matching this entry's end date). 2015-2018 not independently confirmed — real possibility HK wasn't offered, or was offered differently, earlier in this generation. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — all documented locations avoid the head unit |
| Head unit | No replacement needed |
Multiple real build locations documented. Tire jack storage compartment can fit a pair of 8" subs. REAL TIGHT-CLEARANCE CONSTRAINT for down-firing installs: only ~1" floor clearance at the rear, ~2" at the front closest to the rear seats — genuinely tight, worth flagging before assuming a down-fire design will clear. Behind-3rd-row mounting is also real and documented, with the JL Audio W3v3 in its HO (high-output/low-profile) box specifically noted as fitting well there. REAL PRACTICAL NOTE: any cargo-area box needs quick-disconnect mounting so it can be removed when full cargo capacity is needed — this vehicle's owners actively use the space for hauling, not just as a fixed installation location. Amp placement: JL Audio 500/1 fits well under the middle rear seat, with connections accessed from the rear trunk.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.

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.
