2015-2020 Chevrolet / GMC Tahoe / Yukon / Suburban / Yukon XL GMT K2XL — 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 SUV

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 Likely

Locationcargo area behind 3rd row, below cargo cover (retailer-measured, promoted from existing notes)
Outer bounding box49"W x 14"H x 31-33"D. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2015-20 Chevy Tahoe Sub Box Downfire Sealed Large Third Row': 48 x 15 x 20 in (as printed; axes not labelled), 5.02 ft3, behind third row seat; NET Audio '2015-20 Chevy Tahoe Sub Box Downfire Cargo Bin Third Row Box Shallow 10s': 50 x 6 x 17 in (as printed; axes not labelled), 1.16 ft3, third-row cargo bin (removable bin); SRQ Customs 'Chevy Tahoe and GMC Yukon Subwoofer Enclosure': 50 x 22 x 8 in (as printed; axes not labelled), 1.2 ft3, rear cargo area compartment (sits on top, or lower if the compartment door is removed); not XL. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: Ground Shaker 'BLACK 10" SINGLE SEALED SUB BOX, FITS 95-24 CHEVY TAHOE (w/3rd row seat)': Height 18", Length 25 1/2", Top Depth 10 1/4", Bottom Depth 13 1/2" (labelled by Ground Shaker), 1.53 FT3, behind the 3rd row seat; Ground Shaker 'BLACK 10" DUAL SEALED SUB BOX, FITS 95-24 CHEVY TAHOE (w/3rd row seat)': Height 18", Length 41 1/2", Top Depth 10 1/4", Bottom Depth 13 1/2" (labelled by Ground Shaker), 2.58 FT3 (2 chambers), behind the 3rd row seat.

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 Likely

Factory speaker size6.5"
Known obstructionsNone specifically documented
Adapter bracket neededyes
TweeterDash corner, not the door or A-pillar directly — a somewhat unusual location/size, distinct from the more common A-pillar convention seen on the older GMT800/GMT900 companion pages.

Rear doors Likely

Factory speaker size6.5" (same as front)
Known obstructionsNone specifically documented
Adapter bracket neededno
Tweetern/a — tweeter is dash-corner, front only

Factory audio integration

Factory amp / premium audioAsymmetric finding between the two badges — do not treat Tahoe/Yukon as identical here. GMC Yukon: Bose became STANDARD equipment with the 2015 redesign (not optional/trim-gated — a genuine difference from most GM Bose fitments, which are upper-trim-only). Chevrolet Tahoe: Bose remained a package/trim-gated option, offered in two tiers — 9-speaker with a Richbass woofer, or a 10-speaker tier adding AudioPilot/Centerpoint/SurroundStage processing. Exact Tahoe trim names gating each tier not independently confirmed.
Adding subs without a head-unit swapSame as the 2000-2006 generation — large cargo area supports a standalone enclosure without needing to tap factory wiring
Head unitNo replacement needed

Known integration products

Mounting locations

Standard Solid

Retailer-measured: 49"W x 14"H x 31-33"D below the cargo cover with 3rd row seats up. Slightly less height than the 2000-2006 generation (14" vs 16") but more depth (31-33" vs 27-28"). Secondary source — GM figures as reported by GM Authority; GM's own media site returned 403: cargo volume 15.3 cu ft behind the third row, 51.7 behind the second row, 94.7 behind the first row (2015-2020 Tahoe; Yukon not separately stated). Whole-cargo volumes, not box space.

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.
