2023-2025 Honda Pilot 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.

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

Locationcargo area (on top of the cargo cover, confirmed hatch clearance)
Outer bounding boxno precise dimension published, only the confirmed hatch-clearance fact above. Honda publishes no cargo width or length. Honda 2023 press kit: underfloor storage "up to 3 cu. ft. (EX-L, Touring, Elite)", and "at its deepest point, the larger underfloor storage adds 5.5 inches of storage depth".
Known obstructionsnone reported for a sub sitting on the cargo cover itself

Enthusiast

Subwoofersno molded enclosure confirmed for this generation yet — Skar Audio's Pilot-specific side-firing enclosure (10", pre-loaded VS-10 D2) is directly confirmed scoped to 2016-2022 (3rd Gen) only; a custom sealed build using the confirmed real cargo-cover-clearance fact is the more reliable enthusiast path until a 4th-gen product surfaces

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
TweeterA-pillar/sail area, on EVERY trim: Honda's 2023 press kit says the 7-speaker LX/Sport system has "one in each door, a tweeter in each A-pillar and an 8-inch subwoofer in the cargo area". The 0.75" size is a forum figure for the Bose trims; Honda gives no size.

Rear doors Unconfirmed

Adapter bracket neededunconfirmed
TweeterRear doors on the 9-speaker EX-L/TrailSport system: Honda lists "two additional tweeters in the rear doors". Not stated for the 7-speaker or Bose systems. Size not published.

Factory audio integration

Factory amp / premium audioThree tiers per Honda: LX and Sport 240W, 7 speakers including a subwoofer (a tweeter in each A-pillar and an 8-inch subwoofer in the cargo area); EX-L and TrailSport 245W, 9 speakers including a subwoofer (adds two rear-door tweeters); Touring, Elite and (2025 only) Black Edition, Bose premium, 12 speakers including a subwoofer. Every tier has a factory subwoofer. CONFLICT inside Honda for 2023 Touring: the 2023 press kit and Info Center put Touring on the Bose 12-speaker system, but the 2023 spec sheet lists Touring at 245W/9 speakers with Bose on Elite only; the 2025 spec sheet puts Touring, Elite and Black Edition on Bose.
Adding subs without a head-unit swapConfirmed, and genuinely easy per owner reports — the cargo area comfortably fits an added sub box even on top of the factory cargo cover.

Standard Solid

Full redesign confirmed — this generation added the off-road-styled TrailSport trim alongside the existing lineup. Two confirmed factory audio tiers via Honda's own official Info Center pages: EX-L and TrailSport get a 9-speaker system (includes a subwoofer) with a 245W amp; Touring, Elite, and (2025 only) Black Edition get the Bose70 12-speaker premium system (also includes a subwoofer). Practical owner-confirmed detail: an aftermarket subwoofer box can sit on top of the factory cargo cover and the power hatch still closes fully.

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.
