2013-2018 Hyundai Santa Fe 3rd Gen (DM) — 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 Likely

Locationcargo area, custom shallow build
Outer bounding box~7" clearance available in the cargo area; real build example 24"x24"x6"/6.5" with mounting legs
Known obstructionsLow clearance forces shallow-mount drivers only (e.g. 4.5"-shallow 15") — do not assume standard-depth drivers fit
Usable volume estimate1.5 ft³

Starting points

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

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

Factory speaker sizeunconfirmed — no specific factory size surfaced despite a dedicated search
Adapter bracket neededunconfirmed
TweeterReal, confirmed genuine OEM tweeter part exists (part # 96310-4Z200, listed for 2013-2018 Santa Fe Sport), Infinity-equipped trims. Exact location (dash vs. A-pillar) and diameter not confirmed. Real, important install caution: no Crutchfield-available wiring adapter OR mounting bracket exists for this location — any aftermarket tweeter swap needs spliced wiring and a fabricated bracket.

Rear doors Unconfirmed

Factory speaker sizeunconfirmed
Adapter bracket neededunconfirmed
Tweetern/a — tweeter is front only

Factory audio integration

Factory amp / premium audioReal, confirmed with a naming correction worth flagging. Infinity premium speakers confirmed real, bundled into the Technology package for 2018 (also adds nav, panoramic sunroof, heated steering wheel/rear seats, ventilated front seats) — a real package bundle, not a stand-alone audio option. NOTE: no source found calling this system 'Infinity Dimension' — that more elaborate naming belongs to a later/different Hyundai generation (e.g. Palisade); this generation's system should be referred to as plain Infinity unless a source specifically confirms otherwise. Earlier years within 2013-2017 not independently confirmed.
Adding subs without a head-unit swapConfirmed straightforward — cargo-area builds don't touch the head unit
Head unitNo replacement needed

Mounting locations

Standard Likely

Real cargo space: 36.4 ft3 behind rear seats, 72.1 ft3 seats folded (72"L x 45"W x 30"H folded, 43"W x 29"H opening). Real documented custom build: 24x24x6" (6.5" with mounting legs), 1.318 ft3 raw, brought to the recommended 1.5 ft3 with polyfill — real ~7" of clearance available in the cargo area to work with. A professional installer specifically used a Polk MM1540, a 4.5"-shallow-mount 15" driver, to fit the low-clearance space while still running a genuinely large 15" cone. REAL MATERIAL LESSON, worth keeping as a general build-quality note: an initial build using 1/2" MDF to save space had too much panel flex and poor resulting sound quality — proper (3/4") material thickness matters for structural rigidity and acoustic performance, not just fitting the space.

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.
