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 (identical across Tahoe/Yukon XL/Escalade ESV/Suburban 1500 per confirmed platform-sharing) |
|---|---|
| Outer bounding box | Width between wheel wells ~48-48.25"; ground-to-rear-load-floor height 32.3"; depth not independently measured |
| Known obstructions | None documented — open cargo area, free-standing build territory |
| Usable volume estimate | 8 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x12" or 1x15" sealed |
|---|---|
| Box type | sealed |
| Location | cargo area, free-standing |
| Subwoofers | 2x12" or 2x15" ported |
|---|---|
| Box type | ported |
| Location | cargo area, free-standing (108.9 ft3 total cargo volume available) |
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) — real, 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 | likely 6.5" per forum sourcing — weaker confidence than the front, Crutchfield's own guide didn't state rear size explicitly |
|---|---|
| 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. Real, 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. |
|---|---|
| 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 |
IMPORTANT PLATFORM-SHARING FACT, independently confirmed: the 2007-2014 Tahoe, GMC Yukon XL, Cadillac Escalade ESV, and Chevrolet Suburban 1500 all share the SAME chassis, wheelbase, roofline, and rear cargo compartment geometry — an enclosure engineered for one fits all four without adjustment. This is a real structural fact, not a guess, and means this single entry can responsibly cover all four badges/models for this generation. Real measurements: cargo volume 108.9 ft3, ground-to-rear-load-floor height 32.3", width between wheel wells ~48-48.25".
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.
