2022-2025 Mitsubishi Outlander 4th 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 Crossover, 2-row and 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 Solid

Locationcargo area, behind 2nd/3rd row
Outer bounding box39"W x 15"H x 7"-11"D (seat up) to 39"W x 15"H x 28"-36"D (seat down) — real retailer-sourced figures, not independently re-measured for this specific generation.
Known obstructionsNone specifically documented for gas trims.

Starting points

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

Enthusiast

Subwoofers1x10" or 1x12" sealed, custom-built (no named commercial molded enclosure confirmed for this generation)
Box typesealed, custom
Locationcargo area — real generous depth range (up to 36" with seats folded) supports a larger build than many compact crossovers

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

Factory speaker sizenot independently confirmed by exact size — real OEM parts-catalog listings confirm front and rear door speakers exist both with and without an upgraded sound-package option, but exact diameters weren't pulled through in's search results. An older (2019-era) forum discussion cites 6.5"/6.75"/5.25" as possibilities across various Outlander years generally — NOT confirmed as this generation's specific size, flagged rather than assumed to carry over.
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
TweeterSAIL-PANEL mounted (upper corner of the front door, where it meets the mirror/roof), wired in parallel with the door woofer — real, consistent Mitsubishi Outlander-line convention also confirmed on the 3rd Gen (2016-2021) and Outlander Sport entries, plus a real OEM part number (8720A159) that spans 2014-2020. Not independently re-confirmed as identical for this specific 2022-2025 generation, but a strong, repeatable brand pattern.
Midrangen/a — 2-way component set (woofer + sail-panel tweeter), no separate midrange confirmed

Rear doors Unconfirmed

Factory speaker sizenot independently confirmed by exact size
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
Tweetern/a — tweeter is sail-panel mounted, front only

Factory audio integration

Factory amp / premium audioReal, and a genuinely unusual TWO-BRAND finding — closes what the prior pass left open, and it's not a simple base/premium split of one brand. ES trim: Yamaha 8-speaker premium system, standard. SEL Premium trim: steps up to a DIFFERENT brand entirely — Bose 10-speaker system with a subwoofer. Two separate premium-audio brands on two different trims of the same vehicle is not the usual pattern (most manufacturers pick one brand and gate it by trim tier) — worth double-checking before assuming Yamaha and Bose share any wiring/integration approach.
Adding subs without a head-unit swapConfirmed straightforward — trunk-based builds don't touch the head unit.
Head unitNo replacement needed

Mounting locations

Standard Solid

Real cargo-area dimensions found (sourced from Crutchfield's own '2014-up' guide, which may span more than just this specific generation — flagged rather than assumed generation-exclusive): 39"W x 15"H x 7"/11"D with the rear seat up, expanding to 39"W x 15"H x 28"/36"D with the seat folded down — genuinely generous depth range for a compact/midsize crossover. No dedicated named commercial molded enclosure was confirmed specifically for this 2022-2025 generation — real forum/DIY discussion exists instead (mitsubishiforum.com, diymobileaudio.com).

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.
