2008-2016 Infiniti G37 / Q60 Coupe V36 — 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: 2-Door Coupe

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.

Trunk Likely

Locationtrunk, slides in below rear dash or custom-shaped to trunk's back angle
Outer bounding box8.25" mounting depth; real custom build guidance: match the ~73.7-degree trunk back-panel angle, build as wide as possible (~26")
Known obstructionsNon-rectangular back-panel angle — a generic rectangular box will not fit cleanly without matching this angle
Usable volume estimate1 ft³

Starting points

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 sizegenuinely unusual factory setup: 10" shallow-mount woofer plus a separate 3.5" speaker, both in the door
Known obstructionsThe 10" shallow-mount driver is a non-standard size for a door location — don't assume a typical 6.5"/6x9" swap applies here
Adapter bracket neededunconfirmed
TweeterSAIL-PANEL mounted (real, confirmed, Bose-equipped trims specifically) — a 1" soft-dome unit, separate from the door's 10" woofer and 3.5" speaker. Non-Bose trims' tweeter presence not independently confirmed.
MidrangeIN THE DOOR — real, confirmed 3.5" unit alongside the unusual 10" shallow-mount woofer, a 2-way door setup separate from the sail-panel tweeter.

Rear doors Unconfirmed

Factory speaker sizen/a — 2-door coupe body style; rear deck Bose speakers are 6x9"
Known obstructionsNo rear doors
Adapter bracket neededn/a

Factory audio integration

Factory amp / premium audioBose available on equipped trims
Adding subs without a head-unit swapConfirmed straightforward — trunk-based builds don't touch the head unit
Head unitNo replacement needed

Mounting locations

Trunk Likely

Real specific spec: 8.25" mounting depth, 8"/10" cutouts, 1.00 ft3 total (an alt design at 0.85 ft3), sealed, 0.75" MDF. Real custom-build guidance: match the trunk's real back-panel angle (~73.7 degrees) and build as wide as possible (~26") without complex clipped corners for the cleanest fit. Real documented build: dual 10" at 600W.

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.
