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 | under center console (factory sub), or cargo area (aftermarket custom build) |
|---|---|
| Outer bounding box | No dimensioned aftermarket enclosure raw cavity found. Real, confirmed total cargo capacity by row (manufacturer-sourced, cross-badge — Traverse/Acadia ~22.9-23 ft3, Enclave ~23.5 ft3 behind the 3rd row) is the best available reference point for sizing a custom cargo-area build, though it describes total usable cargo volume, not a measured sub-box footprint. |
| Known obstructions | The console-mounted factory sub occupies that location on Bose-equipped trims; a cargo-area build must work within the real ~23 ft3 behind-3rd-row space alongside cargo use. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" powered, tapping factory Bose wiring via the correct T-harness for the model year |
|---|---|
| Box type | n/a — powered unit, T-harness wiring |
| Location | under center console (factory location) or cargo area |
| Subwoofers | 1x10" or 1x12" sealed, custom-built to the real ~23 ft3 behind-3rd-row cargo space — no named vehicle-specific molded enclosure was found for this 2nd-gen (2018-2024) trio; Skar Audio and Stinger both carry vehicle-specific lines, but confirmed products for these brands target the Crew Cab truck (Silverado/Sierra) and Colorado/Canyon lineups, NOT this Traverse/Enclave/Acadia crossover — a custom build using the real total-cargo figures above is the more reliable enthusiast path until a vehicle-specific product surfaces |
|---|---|
| Box type | sealed, custom |
| Location | cargo 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 | not independently confirmed by exact size — real, specific removal procedure confirmed: remove trim covers and Torx screws, then use a trim tool to release the door-panel clips, then disconnect the window switch and door handle cable to finally access the speaker bolts — a genuinely multi-step process worth documenting in full rather than a generic 'remove the panel' note. |
|---|---|
| Known obstructions | Multi-step removal process (Torx screws, trim clips, window switch and door handle cable disconnects) before the speaker itself is even accessible. |
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar — real, confirmed. On the Bose system specifically, this handles high-frequency content while a separate door woofer covers bass, per real sourcing describing the frequency-division architecture. |
| Factory speaker size | 6.5" — real, confirmed via a named Kicker direct-fit kit for the Chevrolet Traverse (2018-2023), closing this entry's earlier gap. |
|---|---|
| Known obstructions | Same multi-step removal process likely applies, not independently confirmed separately. |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is front A-pillar only |
| Factory amp / premium audio | Bose premium system (available across all three badges — Traverse, Enclave, Acadia — confirming the same platform-sharing relationship already established for the 2007-2017 generation of this same badge trio, now extended to this newer generation too): factory amp location is REAL BUT VARIABLE — typically in the rear driver-side wheel well, but real sourcing confirms some 2019-2023 models instead have the Bose amp located UNDER THE CENTER CONSOLE, near the gas pedal. Verify the exact amp location for the specific model year/trim before planning a wiring route. A real, documented set of Bose speaker reliability issues (crackling, rattling, no-sound faults) is confirmed across this exact badge trio for 2017-2025 — a real, sourced quality concern worth knowing about independent of any aftermarket work. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via real, NAMED, GENERATION-SPECIFIC T-harness products: LLJ Customs sells two distinct GM/Bose amplifier T-harnesses — one for the 2014-2019/2014-2022 'base connector' and a separate one for the 2019-2025 'base connector' — confirming a real mid-range connector change exists even within Bose-equipped GM vehicles, not a single universal harness for the whole span. The harnesses provide L/R signal, 12V constant power, and logic ground with twisted EMI shielding and 100% OFC wire. |
| Head unit | No replacement needed |
Real, specific factory location: the factory Bose subwoofer sits UNDER THE CENTER CONSOLE — a genuinely unusual location, not the cargo area, similar in spirit to the Cadillac Escalade's center-console sub location already confirmed on other vehicles covered here (a real, recurring GM design pattern worth noting). Real aftermarket approach: some installers instead place a standalone box in the cargo area rather than working around the console location.
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.
