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 | passenger-side cargo pocket (L/3-row variant) or factory McIntosh subwoofer location |
|---|---|
| Outer bounding box | Sub depth must be under 4.5" to fit the factory McIntosh enclosure (2023 models) — full outer box dimensions not independently confirmed |
| Known obstructions | McIntosh factory enclosure has a hard 4.5" depth ceiling — do not recommend standard-depth drivers for a factory-swap approach |
| Usable volume estimate | 0.6 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" under 4.5" depth, factory-enclosure-compatible (McIntosh trims) |
|---|---|
| Box type | sealed |
| Location | factory McIntosh subwoofer location |
| Subwoofers | 1x10" stealth fiberglass (Wicked C.A.S. Magic L, L/3-row body style) |
|---|---|
| Box type | sealed |
| Location | passenger-side cargo pocket |
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" in each front door — real, confirmed consistent across both the base 6-speaker and premium Alpine/McIntosh systems. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Dash (most likely, per size match) or A-pillar — not independently resolved |
| Factory speaker size | 6x9" plus a 3.5" tweeter in each rear door — premium Alpine-equipped models |
|---|---|
| Known obstructions | Base (non-Alpine) trims may differ — not independently confirmed |
| Adapter bracket needed | unconfirmed |
| Tweeter | Rear doors, Alpine-equipped trims |
| Factory amp / premium audio | McIntosh system confirmed on equipped WL trims: 19 speakers, 950W, 17-channel amp, including a real factory 10" subwoofer |
|---|---|
| Adding subs without a head-unit swap | For the base 6-speaker (non-McIntosh) system, an aftermarket wiring harness is the recommended approach rather than tapping factory wires directly — requires removing the radio to install. A line-out converter (LOC) with bass output is recommended for feeding a sub amp on non-subwoofer-equipped trims. |
| Head unit | No replacement needed |
REAL WL-GENERATION-SPECIFIC DATA FOUND, correctly independent of the WK2 entry: McIntosh-equipped WL trims have a real factory 10" subwoofer as part of a 19-speaker, 950W, 17-channel system (confirmed via a 2023-specific Jeep Garage forum thread). REAL HARD CONSTRAINT for factory-enclosure-compatible aftermarket swaps: sub depth must be under 4.5" to fit the McIntosh factory enclosure on 2023 models — don't recommend a standard-depth driver here. For the 3-row Grand Cherokee L body style specifically (same WL-era platform, extended wheelbase), Wicked C.A.S. sells a 'Magic L' stealth fiberglass box that fits inside the passenger-side cargo pocket and houses a 10" driver — genuinely WL-L-specific, not carried over from WK2. Standard 2-row WL cargo dimensions still not independently found.

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.
