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 (retailer-measured, promoted from existing notes) |
|---|---|
| Outer bounding box | 49"W x 16"H x 27-28"D. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2000-2006 Chevy Tahoe Sub Box Downfire Sealed': 49 x 15 x 25 in (as printed; axes not labelled), 4 ft3, behind seat, keeps the third-row seating. 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. |
| Known obstructions | Factory sub cutout (if OEM-equipped) is a distinct, smaller anchor point within this larger cavity: depth ~4.5" tapering to 7.75", hole center 11-12" from floor, ~18" total usable height |
| Usable volume estimate | 12 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 (large usable volume for this platform) |
| Subwoofers | 1x8" to 1x12" depending on exact location |
|---|---|
| Box type | sealed, factory-look or StealthBox-style |
| Location | driver's side rear panel, under 2nd row seat, or center console (GMT820 short-wheelbase) |
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" (also fits 5.25") — confirmed via Crutchfield's combined guide covering Tahoe/Suburban/Yukon/Yukon XL/2002 Escalade. Additional confirmation: this is GM's own 'oversized 6.5"' spec, which is really 6.75" — same terminology/sizing convention already confirmed on our Silverado/Sierra and Escalade pages (same corporate platform family). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | no |
| Tweeter | A-pillar — confirmed. Named cross-badge aftermarket product spans this Tahoe/Yukon generation AND the Avalanche, Suburban, Silverado, Sierra, and Cadillac Escalade of the same 2000-2006 era together — an extensive cross-badge platform-sharing case matching the pattern already tracked on other vehicles covered here for GM full-size trucks/SUVs. |
| Factory speaker size | 6.5" (same as front, same guide) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | no |
| Tweeter | n/a — tweeter is front A-pillar only |
| Factory amp / premium audio | Bose confirmed on upper trims 2003-2006, with a complete architecture: A-pillar tweeters (~2"), 3.5" center dash speaker, and a 6" subwoofer under the center console. Exact per-year/trim breakdown for 2000-2002 not independently confirmed. |
|---|---|
| Adding subs without a head-unit swap | Large open cargo area makes this one of the easier platforms — plenty of room for a standalone enclosure without touching factory wiring at all if using the open cargo space rather than the factory sub cutout |
| Head unit | No replacement needed |
Measured cargo space: 49"W x 16"H x 27-28"D behind the rear seats. Factory subwoofer cutout (on OEM-equipped trims): depth ~4.5" at bottom tapering to 7.75" at top, hole center 11-12" up from cargo floor, ~18" total usable height. Separately confirmed: a commercial 'StealthBox' product line exists for this platform specifically (factory-look integrated enclosure, no cargo space lost) — this is a distinct product category worth its own recommended tier, not just a DIY afterthought. 'GMT820' naming (vs. GMT800 used elsewhere for this era) needs reconciling — may refer specifically to short-wheelbase trims; noted as-found rather than guessed at.
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.
