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: 2-Door Coupe (2+2)
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, side-mount; or rear seat/rear-seat-delete area |
|---|---|
| Outer bounding box | Shared with the BRZ page — no independently measured raw envelope found, but the real cross-generation box-fitment confirmation is itself strong evidence of a consistent physical envelope across both generations. |
| Known obstructions | Same low-current-ground trap and factory wire channel already documented in the BRZ page — this is genuinely shared platform wiring, not independently re-verified separately per badge. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | Toyota-branded Kicker or OEM side-mount trunk sub (real factory option, easy-disconnect for track days) |
|---|---|
| Box type | n/a — factory option |
| Location | side of the trunk |
| Subwoofers | 1x10" or 1x12" custom, rear-seat-delete build |
|---|---|
| Box type | custom, cut into a rear-seat-delete tray |
| Location | rear seat area |
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 | 6.75" — confirmed for 2022-2023 GR86 (2nd Gen) via the same detailed forum-sourced upgrade-data thread cited on the BRZ page (the thread explicitly covers both '2022+ GR86 Premium' AND 'BRZ Limited' together, confirming shared hardware). |
|---|---|
| Known obstructions | Same BTL 2-ohm factory amp on Premium-trim cars as documented on the BRZ page — a straight 4-ohm aftermarket swap will underperform without accounting for this. |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | n/a — 2-door coupe; equivalent locations are the dash (3"/4") and rear side panels (4"), same as the BRZ page. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Rear side panel/speaker location |
| Factory amp / premium audio | Base (6-speaker) vs. Premium (8-speaker, adds dash tweeters + BTL 2-ohm amp) — identical trim structure to the BRZ's Limited trim, confirmed via a forum thread that explicitly covers both badges together as one system. Toyota's own 2022 release: 'a six-speaker audio system comes on the base grade; that increases to an eight-speaker system on the Premium', and 'a dealer or factory-installed 10-inch, 200W subwoofer is available for either grade' (Toyota does not name Kicker for it). Scion FR-S 2016 release: 'The eight-speaker sound package features a Pioneer audio system', with 'a separate two-channel amplifier ... to drive power to the door-mounted woofers'. No Toyota trunk volume found; Subaru's BRZ figure is not borrowed. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via the same shared gr86.org/ft86club.com community documentation as the BRZ page — this is genuinely one shared knowledge base across both badges, not duplicated independently. |
| Head unit | No replacement needed |
this page shares its full cargo-fitment findings with the sister Subaru BRZ 2013-2025 page — SAME platform, same body, same trunk shape across both badges. Specific, genuinely unusual Toyota-branded factory feature: an OEM side-mount trunk subwoofer with an EASY DISCONNECT specifically for track days, plus a Toyota-branded Kicker factory option. Aftermarket brand Basser makes 1st-Gen-specific boxes CONFIRMED via direct owner testing to also fit 2nd-Gen (GR86) cars, since the trunk carried over despite the engine/generation change. See the BRZ page for the full rear-seat-delete custom-build details.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.
Each link opens the tool with this vehicle already selected.
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.
