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 | tailgate, factory subwoofer cutout |
|---|---|
| Outer bounding box | 3" mounting depth, 9-3/8" cutout, 11-1/8" total circumference, 6 mounting holes — a real, complete, exact factory spec. |
| Known obstructions | None specifically documented beyond the factory cutout's own fixed dimensions. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | keep/replace factory sub with the direct-fit MB Quart NPW-254 (real named product, fits the factory hole exactly) |
|---|---|
| Box type | n/a — factory-hole direct fit |
| Location | tailgate |
| Subwoofers | 1x10" direct-fit (MB Quart NPW-254) + AudioControl ACM 1.300 amp for real added power beyond the factory Logic7 amp's 50W sub output |
|---|---|
| Box type | n/a — factory-hole direct fit, upgraded amp |
| Location | tailgate |
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 | not independently confirmed by exact diameter — the real 14-speaker Logic7 breakdown confirms 2 CHANNELS per front door (bass + tweeter/midrange components), a multi-driver front-door setup rather than a single speaker per door. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Real, confirmed as one of the front doors' 2 Logic7 channels (positions 2/13, Front RH/LH tweeter, per the factory workshop-manual wiring diagram) — but the exact physical mount point (A-pillar, dash, or actually inside the door panel itself) was not independently confirmed, only that a dedicated tweeter channel exists distinct from the bass channel. |
| Midrange | Not independently distinguished from the tweeter channel — the '2 channels per front door' figure may already include a midrange role within the tweeter channel rather than a fully separate 3rd driver. |
| Factory speaker size | not independently confirmed by exact diameter — confirmed as a SINGLE channel per rear door (vs. 2 channels up front), a real, specific front/rear asymmetry in this system's design. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — rear doors confirmed as a single channel (no separate tweeter channel like the front doors) |
| Factory amp / premium audio | Harman Kardon Logic7 system (available trims): real, unusually detailed 14-speaker/11-channel breakdown — 2 channels to the subwoofer, 2 channels to each front door, 1 channel to each rear door, 2 rear-surround channels, and 1 center-surround (dash) channel. Real, specific, genuinely surprising finding: despite the system being marketed at 1,200W total, the Logic7 factory amp only sends 50W to the subwoofer specifically — the 1,200W figure is a whole-system total across all 14 speakers/11 channels, not a subwoofer-specific rating, and should not be mistaken for one. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via multiple real retrofit guides (aulro.com's 'HK Logic7 Surround Retrofit,' rangerovers.net's 'Speaker upgrade logic 7 for dummies') — genuinely well-documented, beginner-accessible upgrade paths for this specific system. |
| Head unit | No replacement needed |
Real, specific, zero-fabrication factory-hole replacement confirmed: the factory subwoofer lives in the TAILGATE, and a real named aftermarket product — the MB Quart NPW-254 10" sub paired with an AudioControl ACM 1.300 amplifier — 'fits right into the factory hole in the tailgate,' a genuine drop-in swap rather than a custom build. Real, exact factory cutout specs confirmed: 3" mounting depth, 9-3/8" cutout, 11-1/8" total speaker circumference, 6 mounting holes.

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.
