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, 2-row and 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 | cargo tray, extra storage space to one side |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the real owner's 'fits almost perfectly' account is the best available reference point. |
| Known obstructions | 22"-tire trims ship with NO spare tire at all — an electric pump and tire sealant kit lives under the floor in the rear instead, a real, specific packaging difference from lower trims that DO get a compact spare. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" powered, tapping factory Lexicon subwoofer wiring |
|---|---|
| Box type | n/a — powered unit, factory-tap wiring |
| Location | cargo tray's extra storage space (real documented owner location) |
| Subwoofers | 1x10" or 1x12" sealed, custom-built (no named commercial molded enclosure confirmed for the GV80) |
|---|---|
| Box type | sealed, custom |
| Location | cargo area — cross-check GV70 fitment guides as a starting reference per real owner precedent, then verify on-site |
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 size — the 21-speaker Lexicon system's full driver-by-driver breakdown (sizes per location) was not found in's sources, only total speaker count and wattage. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Lexicon premium system (optional, available trims): 21 speakers, 1,050W, with Genesis's QuantumLogic surround-sound processing — the same total wattage figure reported across several Genesis models (G80, GV70), suggesting a shared amplifier platform across the brand's Lexicon-equipped lineup rather than independently-tuned per-model output. A real, already-substantial factory system — treat as a genuine baseline, not an empty slate, before assuming an aftermarket build is starting from nothing. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via real owner builds (genesisowners.com) tapping into stock subwoofer wiring rather than swapping the head unit — the general Genesis-brand tap approach (splice into the factory sub harness for high-pass input, ground at the factory location, power off the battery) documented on the G70/G80 sedan entries is a plausible cross-applicable starting point, though not independently confirmed as GV80-specific wiring. |
| Head unit | No replacement needed |
Real, specific owner-documented approach: a 'hidden' subwoofer install (genesisowners.com, GV80-specific thread) where the owner searched extensively for GV80-specific guidance, found limited dedicated material, and adapted GV70 guides as a reference — the sub was fit into the extra storage space in the cargo tray, described as fitting 'almost perfectly' on one side. This cross-model reliance (GV80 owners borrowing GV70 guidance) is itself a real, useful signal: the two share enough cargo-area structure that GV70-sourced fitment knowledge is a reasonable starting point, though not confirmed identical.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.

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.
