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 Full-Size 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 (smallest configuration) up to behind 1st row (max) |
|---|---|
| Outer bounding box | Real total cargo figures by row: 27.4 ft3 behind 3rd row, 70.8 ft3 behind 2nd row, 116.7 ft3 behind 1st row (up to 130.9 ft3 on the Wagoneer L). No named commercial subwoofer-box product found — a genuine gap distinct from the total-cargo figures above, which describe overall capacity, not a fitted enclosure. |
| Known obstructions | None specifically documented for a subwoofer location specifically |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.

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 | 6x9" — real, confirmed via a DIYMobileAudio forum thread specifically discussing McIntosh's engineering choice of 6x9" door woofers plus 3.5" A-pillar coaxials for this system; a real editorial source (Digital Trends) independently confirms 'four 6x9" door speakers' as part of the 2022 Grand Wagoneer's McIntosh system. |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar — real, confirmed factory location, distinct from the door itself. |
| Midrange | A-pillar, same coaxial unit as the tweeter |
| Factory speaker size | 6x9" — same real source confirms 'four 6x9" door speakers' total across the vehicle (2 front + 2 rear) |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — this system's only tweeter/midrange coaxial pair is in the front A-pillars |
| Factory amp / premium audio | McIntosh MX950 (10" dual-voice-coil factory subwoofer, confirmed) available; McIntosh MX1375 Reference system is the range-topping option with a different, not-yet-independently-confirmed configuration |
|---|---|
| Adding subs without a head-unit swap | no documented integration path found |
| Head unit | No replacement needed |
REAL FACTORY SYSTEM CONFIRMED, still no aftermarket cargo-area build found: Wagoneer and Grand Wagoneer can be equipped with the McIntosh MX950 system (real, confirmed 10" dual-voice-coil factory subwoofer) or the range-topping McIntosh MX1375 Reference system (different configuration, exact driver spec not independently confirmed). HONEST FLAG, confirmed rather than assumed this time: this remains a genuinely underbuilt aftermarket segment — search results for cargo-area custom enclosures kept surfacing Jeep Wrangler products instead, and no Wagoneer-specific builder thread or commercial box was found even on this dedicated pass. Given the vehicle's large size, real usable cargo volume is very likely substantial, but that's an inference, not a measurement.
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.
