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 | driver's-side trunk storage cubby, cargo area behind 3rd row |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found. Best real data point: the NVX BE-TOYHIG3-VS102 (0.54 ft3 total box volume, 10" driver) is confirmed by the manufacturer to install in the driver's-side cubby and fit — treat as a lower bound on available space, not the true max envelope. A lower-confidence aggregator figure suggests ~46"W x 16"H x 7"-15"D for the general cargo area (3rd row up/reclined). |
| Known obstructions | Hybrid trims only: 12V auxiliary battery located at the rear of the cargo compartment, LEFT side, behind a panel — CONFIRMED side for this generation (distinct from the 4th Gen/XU70 entry, where the equivalent battery's exact side is unresolved; do not assume the two generations share the same side). JBL-equipped trims: factory subwoofer + amp occupy part of the driver's-side rear cargo floor (see audio_integration). |
| Usable volume estimate | 0.54 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" powered, reusing the factory JBL enclosure per the toyotanation.com reuse thread (JBL trims only) |
|---|---|
| Box type | n/a — factory enclosure reuse |
| Location | driver's-side rear cargo floor, factory JBL sub location |
| Subwoofers | 1x10" sealed (real named-brand product: NVX BE-TOYHIG3-VS102, 0.54 ft3, 500W RMS) |
|---|---|
| Box type | sealed |
| Location | driver's-side trunk storage cubby — confirmed minimal cargo-space impact by the manufacturer |
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 | not independently confirmed by exact size — JBL-equipped trims rate front door speakers at 4W (very low, efficiency-tuned per forum sourcing), non-JBL base size unconfirmed |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | not independently confirmed by exact size — JBL-equipped trims rate rear door speakers at 8W per forum sourcing |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is cargo-door mounted, not in the passenger doors |
| Factory amp / premium audio | JBL GreenEdge premium system (Limited trims): 12 speakers across 10 locations, including a pair of 3" tweeters and an 8" subwoofer mounted in the cargo door area. Toyota's own rating (440W) is peak, not RMS — real actual output per forum-sourced teardown is much lower: JBL amp rated ~80W RMS/400W peak driving the sub in bridged mono, factory sub itself only ~8W actual output, front doors 4W, rear doors 8W. JBL amplifier confirmed located on the driver's-side rear cargo floor (2022 model-year forum report; not independently confirmed across every year of this range, but consistent with the NVX enclosure's driver's-side install location). IMPORTANT SAFETY NOTE for Hybrid trims specifically: do not exceed 30A current draw or 350W RMS when upgrading components — high-draw aftermarket audio can affect the hybrid electrical system. |
|---|---|
| Adding subs without a head-unit swap | Real forum discussion exists specifically about adding a powered subwoofer to the stock JBL head unit (ToyotaNation thread), and about replacing the OEM JBL sub using the factory enclosure itself as a mounting point — confirms both a tap-in path and a reuse-the-factory-box path are live topics for this generation. Exact tap point/part number not independently confirmed. |
| Head unit | No replacement needed |
This generation has its OWN dedicated named-brand molded enclosure — NVX BE-TOYHIG3-VS102, a custom-fit 10" sealed hand-laid-fiberglass box that installs specifically in the driver's-side trunk storage cubby and 'sacrifices very little space' per the manufacturer listing. This is the SAME product already documented (as a generation-mismatch reference) in the 2020-2025 (4th Gen/XU70) entry — confirming directly that the aftermarket audio industry treats these as two genuinely different shapes, not a facelift. A separate spec-aggregator figure (ItemFits) cites ~46"W x 16"H x 7"-15"D of cargo-area space with the 3rd row up and reclined — lower-confidence than the NVX product spec since it's aggregator-sourced, not retailer/manufacturer-confirmed.

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.
