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
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | cargo area behind rear seats (Tahoe / Yukon; a shared compartment with the Suburban, Yukon XL and Escalade ESV is not established) |
|---|---|
| Outer bounding box | Width between wheel wells ~48-48.25"; ground-to-rear-load-floor height 32.3"; depth not independently measured. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2007-13 Chevy Tahoe Sub Box Downfire Sealed Medium Third Row': 42.25 x 13.25 x 16 in (as printed; axes not labelled), 2.6 ft3, behind third row seat [only 2007-2013]; NET Audio '2007-13 Chevy Tahoe Sub Box Downfire Sealed Large Third Row': 47 x 13.5 x 24 in (as printed; axes not labelled), 4.2 ft3, behind third row seat [only 2007-2013]. 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. |

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 | 6-3/4" (also fits 6.5" aftermarket) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | no |
| Tweeter | A-pillar (Bose system: one tweeter per side) — named cross-badge aftermarket product spans this Tahoe/Yukon generation AND the Avalanche, Suburban, Silverado, Sierra, and Cadillac Escalade of the same 2007-2014 era together — same extensive cross-badge pattern already confirmed on the prior GMT800 generation. |
| Factory speaker size | 6.5" — reported by owners for both a Bose and a non-Bose 2007 truck (a wiring-guide site lists 6-3/4" instead; unresolved). 2008-2014 not confirmed. |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is front A-pillar only |
| Factory amp / premium audio | Bose was available on upper trims across this GM full-size SUV generation. Complete architecture confirmed, matching the prior GMT800 generation almost exactly: one A-pillar tweeter (~2") per side, 3.5" center dash speaker. Exact per-model/per-year trim breakdown for base (non-Bose) systems not yet confirmed. 2007 owner posts: 'the BOSE 9 speaker system', 'The amp they use is operating under a two ohm load', Bose speakers 2-ohm, and a 6.5" dual-voice-coil subwoofer under the center console. Later years not covered. |
|---|---|
| Adding subs without a head-unit swap | Large open cargo area supports a standalone enclosure without needing factory wiring at all, same as the other Tahoe/Yukon generations already |
| Head unit | No replacement needed |
PLATFORM-SHARING CLAIM NOT CONFIRMED (2026-10-02): it is not independently confirmed that the 2007-2014 Tahoe, GMC Yukon XL, Cadillac Escalade ESV and Chevrolet Suburban 1500 share the same chassis, wheelbase and rear cargo compartment, so do not assume an enclosure engineered for one fits all four without adjustment. No source is recorded for that, and NET Audio's vehicle-specific 2007-13 Tahoe boxes list only the Chevy Tahoe, GMC Yukon and (large box) Cadillac Escalade — not the Suburban, Yukon XL or Escalade ESV. Treat a Tahoe box as unproven in a Suburban or Yukon XL until measured. Figures kept from the earlier research (source not named, body length not stated): cargo volume 108.9 ft3 (seat position not stated — a luggage rating, not a box volume), ground-to-rear-load-floor height 32.3", width between wheel wells ~48-48.25". This page covers the standard-length Tahoe and Yukon (NET Audio's large box and SubThump also name the standard-length Cadillac Escalade). The Suburban, Yukon XL and Escalade ESV are not covered by any page: Chevrolet's 2012 catalog gives the Suburban a 130.0 in wheelbase and 222.4 in overall length against the Tahoe's 116.0 in and 202.0 in (20.4 in longer), and 45.8 cu ft behind the third-row seat against the Tahoe's 16.9.

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.
