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 Crossover
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | right side of cargo area, or general cargo area |
|---|---|
| Outer bounding box | 34"W x 17"D x 32"(bottom)/27"(top)H — specific, tapered-height figure. UNCONFIRMED FOR THIS GENERATION (2026-10-02): this is the 2010-2017 Equinox's figure (a 2010-2015 guide); no 2018-2024 measurement was found. |
| Known obstructions | Factory Pioneer sub enclosure has a mounting pattern that doesn't match aftermarket subs — expect to drill new holes. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" powered, via the real non-Bose integration harness |
|---|---|
| Box type | n/a — powered unit, harness-tap wiring |
| Location | right side of cargo area, factory location |
| Subwoofers | 1x10" or 1x12" sealed, custom-built |
|---|---|
| Box type | sealed, custom |
| Location | cargo area — 34"x17"x27-32"H is the 2010-2017 Equinox's figure, unconfirmed for this generation |
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" — confirmed via a named Kicker direct-fit kit. Labor estimate: mounting aftermarket door speakers on this generation is reported to require roughly 24 HOURS of drilling, cutting, and Dremel work — a genuinely serious time investment, not a quick swap. |
|---|---|
| Known obstructions | Significant fabrication work required — not a simple bolt-in replacement. |
| Adapter bracket needed | yes, extensive |
| Tweeter | Dash tweeters exist per general sourcing, exact location not pinned down independently, so do not assume it matches the older generation's A-pillar placement. |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | Same extensive fabrication work as the front doors likely applies, not independently confirmed separately. |
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Base system: 6 speakers. Pioneer premium system (available trims): adds a center dash speaker and the 8" subwoofer described above, for 8 speakers total. A separate real Bose option also exists on some trims — owner critique describes the Bose system's bass as 'deep, but not spatial,' a specific, somewhat qualified endorsement rather than a simple thumbs up or down. The Pioneer system and 8" subwoofer described here repeat the 2010-2017 Equinox text; no 2018-2024 source confirms them. Chevrolet's own 2023 Equinox catalog lists a "6-speaker system" as standard and an optional "7-speaker Bose premium audio system" (RS Leather and Infotainment packages), and no Pioneer system; Chevrolet's 2012 catalog lists the "Pioneer Premium 8-speaker Sound System, 250 watts" on the previous generation. No Chevrolet source states a subwoofer or its size for this generation. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a named subwoofer integration harness specifically for 2018-2019 non-Bose Equinox/Terrain (and confirmed to also work on 2020-2021 models) — works at the stock radio location, under the passenger-side glovebox. |
| Head unit | No replacement needed |
Specific factory location: on Pioneer-equipped trims, an 8" subwoofer sits on the RIGHT SIDE of the cargo area — accessing it requires removing the cargo side panel, and installing a replacement requires drilling new screw holes into the factory enclosure since aftermarket subs don't share the factory mounting pattern. Specific, generous cargo dimension confirmed for a standalone box: 34"W x 17"D x 32"(bottom)/27"(top)H, with real room noted for both the subwoofer(s) and the amplifier needed to power them. UNCONFIRMED FOR THIS GENERATION (2026-10-02): the Pioneer 8" right-side subwoofer and the 34 x 17 x 32/27 in cargo figure above are word for word the 2010-2017 Equinox's, which come from a guide covering 2010-2015; no source for the 2018-2024 truck was found. Measure before building. Chevrolet's 2023 catalog gives 29.9 cu ft behind the second-row seat and 63.9 behind the front seats (2023 only, no measurement standard named) — luggage ratings for the whole cargo area, not box volumes.

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.
