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, 3-row
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | round cavity above the spare tire, rear cargo area |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the Cerwin-Vega VPAS12ST's own confirmed fit is the best real reference point. |
| Known obstructions | None specifically documented for gas trims. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x12" powered, spare-tire-well (real named product: Cerwin-Vega VPAS12ST) |
|---|---|
| Box type | n/a — powered unit |
| Location | spare tire well, above the spare, minimal cargo-space impact per real owner reports |
| Subwoofers | Wicked C.A.S. MagicBox stealth fiberglass enclosure (real named product found, 2017-2024 fitment per its own listing — exact driver size/volume not independently confirmed, see reference_builds) |
|---|---|
| Box type | sealed, custom-molded fiberglass |
| Location | cargo area — avoid the spare-tire well if the Cerwin-Vega unit is already installed there |
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 | Non-Fender trims: 7" woofer with a 1.5" or 2" tweeter (sources give both tweeter sizes, not resolved to one). Fender-equipped trims: two 200mm (7.87", commonly rounded to 8") dual-voice-coil woofers per the manufacturer's own described 'lower tones with minimal distortion at high volume' spec. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | Non-Fender trims: 5-1/4" rear woofer. Fender-equipped trims: two 168mm (6.6") speakers per door for smooth low-frequency/midrange response. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Fender premium system (available trims, expanded to the Atlas Cross Sport per a real Panasonic Automotive press release confirming the partnership): 12 total Fender speakers, 480W. Full breakdown per the manufacturer: two 200mm front door woofers, two 168mm rear door speakers, an 80mm front-center-channel speaker, four 60mm soft-dome tweeters, 80mm wide-frequency speakers in the D-pillar, and a 168mm subwoofer housed in a 12-liter (~0.42 ft3) enclosure. This is a real, substantial, already-documented factory system — treat as a genuine baseline before assuming an aftermarket build starts from a blank slate. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via the real Cerwin-Vega spare-tire-well install, which taps the factory 52-pin harness behind the glove box rather than swapping the head unit. |
| Head unit | No replacement needed |
Real, specific, named commercial product: a Cerwin-Vega spare-tire-well subwoofer, confirmed via TWO separate real owner forum threads on vwatlasforum.com describing the same install — a real cavity above the spare tire in the rear cargo area used without sacrificing meaningful cargo space, wiring run via a connector in the 52-pin harness behind the glove box with cables routed along both sides of the vehicle. This is the same general 'spare-tire-well family' pattern already confirmed on several other SUVs.

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.
