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 | Rear cargo area — factory Harman Kardon Premium Sound system includes a confirmed 20-liter bass box; real aftermarket builds also exist (JL Audio TW3 10" pairs, a documented fiberglass build) that either side-mount to preserve the spare tire/tools or replace the factory box location entirely |
|---|---|
| Outer bounding box | Not independently measured — the 0.71 ft³ (20L) figure below is the factory HK bass box's rated volume, not a measured custom-build envelope |
| Known obstructions | Genuinely limited cargo space (see cargo_fitment.notes) — spare tire/tools compete directly with a standalone box's footprint, which is why side-mount stealth fiberglass builds are common here |
| Usable volume estimate | 0.71 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | factory 20L Harman Kardon bass box may satisfy many owners without any aftermarket work |
|---|---|
| Box type | factory |
| Location | factory location |
| Subwoofers | 1x10" or 2x10" JL Audio TW3, side-mounted stealth fiberglass to preserve spare tire/tools |
|---|---|
| Box type | sealed (fiberglass) |
| Location | cargo area side-mount (space-preserving) or standalone (sacrifices spare tire/tools) |
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 | 6.5" mid-range — real confirmed genuine OEM front/rear door speaker part exists (6700363680), confirming this as a known factory location |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a in the door — real, confirmed A-PILLAR mounted (25mm/1"), part of the 14-speaker Harman Kardon system (4 tweeters + 4 woofers + 5 midrange + 20L bass box, 12-channel/900W amp). A genuinely different location from the Ghibli entry, which confirms DASH-CORNER (not A-pillar) tweeter mounting on its base/HK system — a real cross-model architecture difference within the same brand and audio partnership. |
| Midrange | n/a in the door — real, confirmed a genuine OEM 'Center Dashboard Harman Kardon Sound Speaker' part exists, meaning at least one of the system's 5 midrange units is dash-mounted, not door-mounted. Exact count/location of the remaining midrange units not independently confirmed. |
| Factory speaker size | 6.5" mid-range (same as front) |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Not independently confirmed for the rear specifically. The Ghibli entry confirms a real rear-DOOR-integrated tweeter on its system — plausible the Levante follows a similar pattern given the shared 4-tweeter HK count (2 front A-pillar + 2 rear, by elimination), but not confirmed specific to this vehicle. |
| Factory amp / premium audio | Harman Kardon Premium Sound system confirmed, including a real 20-liter factory bass box — a genuinely substantial factory subwoofer, not a token inclusion |
|---|---|
| Adding subs without a head-unit swap | Confirmed real activity exists — JL Audio TW3 10" builds and factory-location amp-rack approaches both documented, avoiding the head unit |
| Head unit | No replacement needed |
Real factory system detail confirmed: the Levante's Harman Kardon Premium Sound system includes a 20-liter bass box as a factory component — a genuinely substantial factory subwoofer enclosure. REAL AFTERMARKET BUILDS CONFIRMED on the follow-up read of the Levante Forum thread: owners have run a pair of JL Audio TW3 10" drivers plus an Arc Audio 1100.1 amp, with one owner noting a single 10" is sufficient for most setups. A documented 2021 Levante custom fiberglass subwoofer + speaker upgrade build exists on YouTube. REAL SPACE CONSTRAINT confirmed directly: the rear cargo area has genuinely limited room, and builders explicitly choose between two tradeoffs — sacrifice the spare tire/tools for a standalone box, or side-mount a stealth fiberglass enclosure to keep both. This aligns with the original finding that the substantial factory bass box reduces (not eliminates) aftermarket demand — real builds exist, they're just less common and skew toward space-preserving designs.

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.
