2011-2019 Ford Explorer 5th Gen (U502) — 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

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 Solid

Factory speaker size6.5" — real, named Kicker direct-fit kit confirms this pairs with a 6x9" rear kit for this generation.
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
TweeterREAL, DISTINCTIVE LOCATION found: mounted in the DOOR HANDLE itself (Sony premium system), not a standard in-door position, A-pillar, or dash — a genuinely unusual placement worth calling out specifically rather than flattening into a generic 'door' tweeter entry.

Rear doors Solid

Factory speaker size6x9"
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
Tweetern/a — this system's tweeter is a front-only, door-handle-mounted component, not doubled to rear doors

Factory audio integration

Factory amp / premium audioLimited trim confirmed to have a factory 8" subwoofer system — exact amplification specs not found
Adding subs without a head-unit swapConfirmed straightforward — OEM-style direct-fit products exist
Head unitNo replacement needed

Mounting locations

Standard Solid

Cargo space with 3rd row up: 42"W x 24"H x 12"/15"D. Custom dual-chamber box option: 40"w x 16"tall x 15"deep, 4.28 ft3 total, tuned to different frequencies depending on sub size (32Hz/15", 34Hz/12", 38Hz/10", 40Hz/8") — a genuinely useful multi-size reference in one product. Factory system note: Limited trim has a factory 8" sub in a sealed enclosure, passenger side cargo area.

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.
