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.

Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: Ground Shaker 'BLACK 10" SINGLE PORTED SUB BOX, FITS 01-26 TOYOTA CAMRY': Height 13 1/2", Length 29", Top Depth 13", Bottom Depth 17" (labelled by Ground Shaker), 2.33 FT^3, Slides up against rear seat; Audio Design SCG '2018-2023 Toyota Camry Subwoofer Box | Phantom Fit': 27 x 18 x 14 in (as printed; axes not labelled), 0.85 Cubic Feet (can be reduced to needed volume), Driver side, passenger side or both sides [only 2018-2023]. |
| Known obstructions | Enclosures are designed to stop at the line where the trunk floor folds upward, and to preserve spare tire accessibility |

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 | genuinely non-standard 6x9"-adjacent factory unit; 6.5" aftermarket fits with an adapter plate covering 5.25"-6.75" |
|---|---|
| Known obstructions | Factory speaker is sized differently than a true 6x9" — don't assume a stock 6x9" replacement bolts straight in |
| Adapter bracket needed | yes |
| Tweeter | A-pillar, upper corner near the windshield. IMPORTANT WIRING CAUTION: this tweeter is wired IN PARALLEL with the front door woofer (not a separate dedicated circuit) — replacing it requires splicing both input and output wires to keep the door woofer working, a genuinely non-obvious integration detail distinct from a simple swap. |
| Factory speaker size | 6.5"-compatible (same adapter plate range as front) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | yes |
| Tweeter | n/a — tweeter is front A-pillar only |
| Factory amp / premium audio | JBL premium system confirmed with a complete 3-way architecture: front door woofers, A-pillar tweeters (25mm horn, wired in parallel with the door woofer), and dash-mounted 80mm 'squawker' midrange speakers. Exact trim breakdown otherwise not confirmed. Toyota's 2018 launch release says the JBL system is "nine speakers" with "an added 10.1-inch subwoofer" — the 3-way list above never mentions the subwoofer. Toyota does not say where it is mounted or give watts. A factory sub changes a sub-install plan (tap its feed or replace it). |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit |
| Head unit | No replacement needed |
Specific commercial specs: 12" sealed single, 8.00" mounting depth, 9.125"/11.125" cutouts (10"/12"), 0.89 ft3/chamber (up to 1.78 ft3 for a single-sub configuration); a 10" sealed option at 0.66 ft3 total, 9.35" cutout, 8.375" max mounting depth. Real installation note: enclosures are designed to stop right at the line where the trunk floor folds upward, and manufacturers explicitly design around maintaining spare tire accessibility.
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.
