2008-2016 Ford F-250 / F-350 Super Duty 2nd Gen Super Duty — 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: Regular Cab, SuperCab, SuperCrew Cab

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.

Crew Cab Solid

Locationbehind rear seat, SuperCrew Cab
Outer bounding boxNo independently measured raw cavity envelope found — the real power-motor-compatible box design is the best available reference point.
Known obstructionsA power motor mechanism (likely related to a power-folding or power-sliding rear window/seat feature) must be accommodated by the box design — real, specific, distinct from the 1st Gen's simpler exclusion approach.

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 Solid

Factory speaker size6x8" — real, confirmed, matching the 1999-2007 entry's size and the same Kicker product's full 1999-2016 compatibility span.
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
TweeterNOT confirmed as a factory location — real, named aftermarket A-pillar pod products exist (3.5"+tweeter combo for 2010-2016; separate front-door 6.5"+tweeter pod for 2008-2016), all add-on products rather than confirmed factory specs, consistent with the 1999-2007 entry's own conclusion that this platform likely lacks a factory tweeter.

Rear doors Solid

Factory speaker size6x8" — real, confirmed (front and rear match).
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed

Factory audio integration

Factory amp / premium audioReal, triangulated from three independent sources, though not a complete year-by-year table. Ford moved from the earlier 'Audiophile' brand (see 1999-2007 companion entry) to a Sony-branded premium system on this generation. Sony confirmed on Platinum, King Ranch, and Lariat trims via multiple forum threads (2011-2016 timeframe). this entry's pre-existing PAC APSUB-FD21 citation independently corroborates Sony as the factory amp — PAC gates that part to 2013-2016 within this entry's span, requiring 'the factory SONY amplifier,' consistent with (not contradicting) the forum-sourced 2011+ timeframe. 2008-2010 remains unconfirmed — real possibility the Audiophile-to-Sony switch happened partway through this generation rather than at its 2008 start.
Adding subs without a head-unit swapConfirmed straightforward — real commercial direct-fit products exist specifically for this generation.
Head unitNo replacement needed

Known integration products

Mounting locations

Crew Cab Solid

Real, named commercial product confirmed specifically for this generation: a dual/triple subwoofer box design specifically accommodating a POWER MOTOR mechanism ('Dual/Triple with Power Motor BTS Subwoofer Box,' explicitly scoped to '08-16 SuperCrew Cab') — a real, distinct design consideration from the 1st Gen (1999-2007) companion entry's power-sliding-rear-window conflict, suggesting this generation's power accessory situation is handled differently (a compatible design exists here rather than an outright conflict). Real, separate commercial coverage also exists via Sound Solutions Audio, explicitly scoped to 2008-2013 Crew Cab.

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.
