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: Access Cab, Double Cab
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | behind/under driver-side rear seat — Goose Gear's seat-delete product line spans 2nd AND 3rd gen (2005-present), suggesting this envelope carries over from the 2016-2023 entry |
|---|---|
| Outer bounding box | 33.25"W (per the cross-generation Goose Gear product); length/depth likely similar to the 2016-2023 entry's 28.875"-36"L range and ~34" depth, not independently re-measured for this specific generation |
| Known obstructions | None specifically documented for this generation beyond what's noted in the 2016-2023 entry |
| Usable volume estimate | 1.5 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" sealed, 5.375" depth |
|---|---|
| Box type | sealed |
| Location | behind driver-side rear seat |
| Subwoofers | 2x12", ~1.8 ft3 |
|---|---|
| Box type | sealed or ported |
| Location | behind driver-side rear seat |
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 | 6x9" (lower front door), with tweeters in the upper front door — 6-speaker system |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Upper front door (not dash/A-pillar like most other Toyota models) — real, confirmed 1/2" factory tweeter, a genuinely small factory size worth flagging for anyone expecting Toyota's usual ~1" dash unit. |
| Factory speaker size | 6.5" (Double Cab) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is front-door only |
| Factory amp / premium audio | Real, body-style-gated finding (not trim-gated the way most of our other JBL entries are). Optional JBL upgraded stereo was available on Double Cab specifically — Standard Cab and Access Cab body styles got only the basic factory stereo, with no JBL option found for them. This is a genuinely different gating axis (cab configuration, not trim level) worth keeping distinct from our usual trim-based premium-audio pattern. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward |
| Head unit | No replacement needed |
Real specific specs: single 10" (9.125" cutout, 5.375" mounting depth, 6.00" optional); dual 12" (11.2" cutout, ~5.9" top mounting depth, ~1.8 ft3 air space). Stealth box design uses.75" ultra MDF, built to fit specifically behind the rear driver seat. SAME real caveat as the 3rd gen: minimal space behind the seat means the seat cannot fold down after install.
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.
