2020-2024 Kia Telluride 1st Gen — 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, 3-row

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, down-firing, spare-tire-drop-point-accessible
Outer bounding boxBox sits ~0.5" taller than the rear seats when folded flat; takes about half the cargo space
Known obstructionsMust remain removable and keep the spare tire drop point accessible — real family-use durability requirement, not just a volume figure
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.

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 Likely

Factory speaker size6.75"
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
Tweetern/a in the front doors — Harman Kardon trims (10-speaker/630W, or a 12-speaker/11-channel variant) DO have a front tweeter, but could not resolve WHERE — real owner forum discussion shows genuine uncertainty/hope among owners themselves about whether it's dash-mounted (firing at the windshield) or A-pillar-mounted, meaning even the community hasn't settled this. Left honestly unresolved rather than guessed at. A separate center-dash speaker (below the window, above center dash) is confirmed distinct from this front tweeter.

Rear doors Likely

Factory speaker size6.75" (same as front)
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
TweeterRear door-mounted (both left and right) — real, confirmed on HK trims. Exact diameter not confirmed.

Factory audio integration

Factory amp / premium audioReal, trim-gated, with a confirmed mid-cycle expansion. Harman Kardon premium audio confirmed on the SX trim throughout 2020-2024. Real expansion found: the EX trim gained a 10-speaker Harman Kardon system starting 2024 — HK is no longer SX-exclusive by the end of this entry's span, a genuine trim-availability change worth keeping distinct from the base 2020-2023 SX-only picture.
Adding subs without a head-unit swapConfirmed straightforward — real documented build taps the rear speaker wires at the pillar next to the front seats via a line-out converter, doesn't touch the head unit
Head unitNo replacement needed

Mounting locations

Standard Likely

Real documented build: box sits about 1/2" taller than the rear seats when folded flat, down-firing design with real clearance underneath for the shallow sub to move (not flush-mounted against the floor). Takes a little over half the cargo space but explicitly still allows access to the spare tire drop point — a real, deliberate design tradeoff, not an accident. An 'L' bracket is used to secure the box against sliding during driving. REAL PRACTICAL DURABILITY NOTE, genuinely relevant for a family 3-row SUV: prefab options (JL Audio named specifically) are noted as durable enough to 'take a beating from strollers' and other family cargo, and are removable for big-haul days — a real family-use-case consideration distinct from pure audio performance.

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.
