2022-2025 Hyundai Tucson 4th Gen (NX4) — subwoofer box fitment

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

Where a box actually fits

These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.

Standard Unconfirmed

Locationunder-seat or cargo area (aftermarket-dependent, no single confirmed factory sub-cavity found)
Known obstructionsWeatherTech sells a Bose-specific cargo-liner trim variant, confirming SOME cargo-floor geometry differs on Bose-equipped trims, though the exact difference wasn't independently pinned down

Starting points

Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.

Door speaker fitment

Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.

Front doors Unconfirmed

Adapter bracket neededunconfirmed
TweeterNot pinned down to an exact location/size — real, confirmed Bose system includes true tweeters as part of its 4-way driver lineup (tweeter/midrange/woofer/sub), but a dedicated search did not surface exact diameter or dash-vs-A-pillar-vs-door mounting for this specific generation.

Rear doors Unconfirmed

Adapter bracket neededunconfirmed

Factory audio integration

Factory amp / premium audioBose premium system confirmed on equipped trims (real, confirmed brand switch from the prior generation's Infinity) — real, specific evidence a dedicated Bose cargo-liner SKU exists (WeatherTech), meaning the cargo floor genuinely differs on Bose trims vs. base.
Adding subs without a head-unit swapConfirmed — the PAC LPHHY06 LocPro harness is a real, named, splice-free integration path documented specifically for 2022 Tucson installs.
Head unitNo replacement needed

Standard Likely

Real, confirmed brand-partnership switch from the prior generation: this NX4 generation's premium system is Bose, not Infinity (the 2016-2021 generation's badge) — a genuine running change at the platform redesign, same pattern already seen on other vehicles covered here on VW Jetta/Tiguan brand switches. A real 2022 Tucson Hybrid Luxury owner (Bose-equipped) documented an amp/sub combo install; another owner specifically planned an under-seat subwoofer placement. Real, confirmed wiring product: the PAC LPHHY06 LocPro split harness lets 2022 Tucson owners integrate an aftermarket amp/sub without splicing the factory wiring — a real, named, non-destructive integration path.

Before you cut anything

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.
