2007-2017 Chevrolet / Buick / GMC Traverse / Enclave / Acadia GM Lambda platform — subwoofer box fitment

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, 3-row

Where a box actually fits

These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.

Standard Unconfirmed

Locationcenter console (shared OEM factory subwoofer box, part 15122608)
Outer bounding boxNot independently measured — OEM part number confirmed shared across all three badges, but no dimensional spec found yet
Known obstructionsFactory location is small/fixed by design (console-integrated); large custom builds would instead use cargo area behind 3rd row (22.9 ft3 total cargo volume there, not envelope-specific)
Usable volume estimate0.5 ft³

Door speaker fitment

Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.

Front doors Solid

Factory speaker sizeunconfirmed exact inches — but a real genuine OEM factory part number was found: GM part 15122601, 'Front Door Radio Speaker,' cross-badge across this platform family same as the subwoofer part
Adapter bracket neededunconfirmed
TweeterA-pillar — real, confirmed. Real, additional cross-badge finding: general sourcing on this platform's A-pillar trim explicitly includes a FOURTH badge, the Saturn Outlook, alongside Traverse/Enclave/Acadia — worth adding to this entry's already-confirmed 3-badge platform-sharing case as a real 4th badge sharing the same A-pillar geometry (Saturn was discontinued in 2010, so only relevant for the 2007-2009 portion of this entry's range).

Rear doors Unconfirmed

Factory speaker sizeunconfirmed
Adapter bracket neededunconfirmed
Tweetern/a — tweeter is front A-pillar only

Factory audio integration

Factory amp / premium audioReal, specific, and per-badge — including a genuine staggered-launch detail our combined entry didn't previously have. Bose premium surround sound (GM option codes UQA/UQS) is confirmed across all three badges within this Lambda-platform entry, but NOT from the same start year: Acadia from 2007 (matches this entry's start), Traverse from 2009, Enclave from 2010 — Traverse and Enclave both launched roughly two model years after Acadia on this shared platform. Premium-tier trim gets a 10-speaker Bose system. Exact trim name per badge (vs. just 'Premium tier') not independently confirmed.
Adding subs without a head-unit swapConfirmed straightforward — the shared factory subwoofer location is a known, bolt-in-friendly anchor point across all three badges
Head unitNo replacement needed

CONFIRMED 5TH CROSS-BADGE PLATFORM-SHARING CASE: a single OEM factory subwoofer box part number (15122608) is sold as fitting the 2009-2017 Chevrolet Traverse, 2008-2017 Buick Enclave, AND 2007-2016 GMC Acadia — a genuine shared factory part across three badges, same pattern as the GM full-size SUVs and Ford/Lincoln cases already logged. All three share a 120.9" wheelbase (further platform confirmation). Cargo behind 3rd row is real and substantial (Traverse: 22.9 ft3 behind 3rd row, 56.6 ft3 behind 2nd row) but this is overall cargo volume, not a specific enclosure-build dimension.

Before you cut anything

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.
