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 | side panel of the cargo area |
|---|---|
| Outer bounding box | sized for an 8" driver (factory spec) — full outer box dimensions not independently published |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | OEM-spec 8" replacement in the factory side-cargo location |
|---|---|
| Box type | factory enclosure |
| Location | side of cargo area, Infinity trims only |
| Subwoofers | Not researched yet (no larger commercial build confirmed) |
|---|---|
| Box type | unconfirmed |
| Location | unconfirmed |
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 | 6.75" (confirmed factory spec) |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | GENUINELY CONFLICTING SOURCING, flagged rather than resolved: one source describes a 1-1/4" tweeter in the front PILLAR; a separate source describes the front door itself as a 2-way component setup with a dedicated 0.75" tweeter alongside the 6.5" midbass. These may describe different trim/system tiers (base vs. Infinity) rather than being a straight contradiction, but that wasn't confirmed — do not assume one figure over the other. |
| Factory speaker size | 6.75" (confirmed factory spec) |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is front pillar or front door mounted, front only |
| Factory amp / premium audio | Infinity premium system confirmed on equipped trims, 6-channel architecture (front/rear/center/subwoofer channels, real confirmed spec). Real, honest limitation noted above — described by reviewers as competent but not as strong as Hyundai's own Sonata/Genesis Infinity-Lexicon systems. |
|---|---|
| Adding subs without a head-unit swap | Confirmed common — multiple real Hyundai/Tucson forum threads cover upgrading the factory sub or adding an aftermarket unit to the factory side-panel location without a head-unit swap. |
| Head unit | No replacement needed |
Real, confirmed factory design: Hyundai mounts the subwoofer on the SIDE of the cargo area (not the floor/spare-tire-well pattern seen on many other SUVs) on Infinity-equipped trims. Real, specific factory driver size confirmed: 8" subwoofer, 6.75" front and rear door speakers. Real, honest comparative finding worth keeping: Hyundai's own Infinity system in the Tucson is described as good but wanting for louder output/more bass, and is explicitly noted as LESS impressive than the Infinity/Lexicon systems in the Sonata and Genesis sedans of the same era — the same badge doesn't mean the same tuning across Hyundai's own lineup.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.
Each link opens the tool with this vehicle already selected.
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.
