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 Sedan
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | trunk, through existing opening |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the NVX and Skar enclosures' own installed volumes are the best real reference points, not a true empty-cavity ceiling. |
| Known obstructions | None specifically documented beyond the two enclosures' own install-side note above. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" sealed shallow-mount (real example: Skar VD-10 D2, pre-loaded in a side-firing enclosure) |
|---|---|
| Box type | sealed, side-firing |
| Location | passenger-side trunk wall |
| Subwoofers | 1x10" sealed (real example: NVX BE-TOYCOR-G11, 500W RMS) |
|---|---|
| Box type | sealed |
| Location | driver's-side trunk |
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 | 6-3/4" (JBL and non-JBL trims both). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Door-mounted (per the 10th Gen entry's own corrected finding, JBL tweeters are near the door handle, not sail-panel; not independently re-confirmed whether this 11th Gen's non-JBL '6-speaker Toyota' package still uses the sail panel the way the 10th Gen's did — flagged rather than assumed to carry the same JBL-vs-non-JBL location split forward.) |
| Factory speaker size | not independently confirmed for true rear DOOR speakers on this generation — the sedan may instead use rear-DECK-mounted 6x9" speakers, the same pattern confirmed on the older 10th Gen (2009-2013) sedan; treat as not researched rather than assume door-mounted rear speakers exist on this generation |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is front only |
| Factory amp / premium audio | JBL-equipped trims run a 2-ohm speaker system (distinct from the standard 4-ohm most aftermarket speakers assume) on the preceding 10th Gen — not independently re-confirmed as carrying over unchanged to this 11th Gen, flagged as a likely-but-unverified continuation rather than assumed identical. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit. |
| Head unit | No replacement needed |
Real, generation-specific commercial coverage from TWO named brands agreeing on this exact year range: NVX (BE-TOYCOR-G11, '500W RMS 10" loaded', explicitly 2014-2018/2014-2019, driver's-side trunk install, 'sacrifices very little space') and Skar Audio (VS-1X10TOYCOR-2014-2019, side-firing, precision-built for an OEM-style fit against the PASSENGER-side trunk wall, pre-loaded VD-10 D2 shallow-mount, 800W max, 1-ohm final impedance). Note the driver-side (NVX) vs. passenger-side (Skar) install-side discrepancy between the two commercial products — both are real, confirmed listings, but not reconciled to one side; likely reflects two different valid mounting approaches rather than an error in either. NVX also sells a full turnkey bass package (enclosure+amp+LOC+wiring) for this same range.
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.
