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 | behind 3rd row (promoted from existing commercial-product notes) |
|---|---|
| Outer bounding box | >12" mounting depth, large enough for up to 4x8"/3x10"/3x12" sealed — the commercial product's own 4.83 ft3 rating effectively describes the usable envelope |
| Known obstructions | None specifically documented |
| Usable volume estimate | 4.83 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" sealed |
|---|---|
| Box type | sealed |
| Location | behind 3rd row, down-fire |
| Subwoofers | 2x12" or 3x10"/12" sealed (real examples: dual JL 12W3v3, Sundown-driver custom build) |
|---|---|
| Box type | sealed |
| Location | behind 3rd row or behind 2nd row |
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" woofer/midrange (confirmed on 2020-2022 Alpine-equipped trims — other trims/years not independently confirmed). Real, precise Harman Kardon Premium tier spec found: the system uses 5 two-way (woofer + built-in tweeter) speakers, which Dodge's own marketing counts as 2 speakers each toward the advertised '19-speaker' total — a real, honest clarification of what that speaker count actually means physically. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | Real, important caution: the A-pillar speaker on HK-equipped trims is NOT easily replaceable due to its mounting hardware — no adapter harness exists, requires splicing the factory wire directly rather than a plug-and-play swap. |
| Tweeter | Built into each of the 5 two-way door/dash speakers (HK Premium tier) PLUS a separate 3.5" 2-way speaker in the dash center. Real, confirmed cross-badge finding: a named commercial A-pillar speaker pod (single 3.5" + single tweeter) is sold explicitly for BOTH 2011-2023 Dodge Durango AND Jeep Grand Cherokee — a genuine new cross-badge platform-sharing case (Dodge/Jeep, relevant for the upcoming Jeep brand pass in this same phase). |
| Midrange | Front doors |
| Factory speaker size | 6.5" two-way (Alpine-equipped trims) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Built into the rear door 2-way units, HK Premium tier |
| Factory amp / premium audio | Real, confirmed: Harman Kardon Premium tier advertised as '19-speaker' but physically built from 5 two-way (woofer+tweeter) units each counted as 2, plus additional single-driver locations — a real, honest clarification of what the marketed speaker count means. |
|---|---|
| Adding subs without a head-unit swap | not confirmed, but the volume of large custom sealed builds (4.83 ft3, dual 12") suggests no major factory-amp blocker for the builds people are actually doing |
| Head unit | No replacement needed |
Commercial box for 2011-2019: 4.83 ft3 airspace, >12" mounting depth, fits up to four 8s, three 10s, or 12s sealed — genuinely large usable volume for this platform. Real builder projects confirm serious builds happen here: a Houston-based builder did a custom enclosure specifically for Sundown drivers (3rd gen), another builder ran dual full-depth 12" JL 12W3v3 subs. Skar Audio also sells a single 10" sealed box rated for the full 2011-2025 range.

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.
