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 3rd row, below cargo cover (retailer-measured, promoted from existing notes) |
|---|---|
| Outer bounding box | 49"W x 14"H x 31-33"D |
| Known obstructions | None specifically documented beyond the cargo cover itself |
| Usable volume estimate | 11 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x12" sealed (real example: Kicker CompRT 8" + 300W RMS amp) |
|---|---|
| Box type | sealed |
| Location | cargo area, free-standing |
| Subwoofers | 2x12" sealed (real example: dual JL Audio W3) or ported |
|---|---|
| Box type | sealed or ported |
| Location | cargo area, free-standing |
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 | 6.5" |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | yes |
| Tweeter | Dash corner, not the door or A-pillar directly — a real, precise, somewhat unusual location/size worth keeping distinct from the more common A-pillar convention seen on the older GMT800/GMT900 companion entries. |
| Factory speaker size | 6.5" (same as front) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | no |
| Tweeter | n/a — tweeter is dash-corner, front only |
| Factory amp / premium audio | Real, asymmetric finding between the two badges — worth keeping separate rather than treating 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 swap | Same as the 2000-2006 generation — large cargo area supports a standalone enclosure without needing to tap factory wiring |
| Head unit | No replacement needed |
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").
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.
Each link opens the tool with this vehicle already selected.
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.
