2009-2014 Ford F-150 Subwoofer Box Fitment

2009-2014 Ford F-150 12th 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: Regular Cab, SuperCab, SuperCrew

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.

Supercrew Likely

Location	underseat, SuperCrew — no dedicated Goose Gear seat-delete product found specifically naming this generation (their line covers 2015+), so envelope inferred from the strong cross-confirmed audio-product ecosystem already in this page
Outer bounding box	Inferred from 4 independent commercial products agreeing on similar usable space: at least accommodates dual-10"/12" configs at 5.2"-6" mounting depth range. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2009-2014 Ford F150 SuperCrew Sub Box Sealed Stage 1': 55 x 16 x 10 in (as printed; axes not labelled), 1.75 ft3, under seat; NET Audio '2009-2014 Ford F150 SuperCrew Sub Box Single Sealed Stage 1': 30 x 16 x 10 in (as printed; axes not labelled), 0.89 ft3, under seat. Published box footprints are lower bounds on the cavity, not the cavity: Kicker 51KFDL7T102 dual 10" L7T enclosure, labelled by Kicker: 55-1/8 in wide x 8-1/4 in high x 13-3/8 in deep, fits F-150 Crew Cab 2009-2026; SRQ Customs 'Ford Crew Cab Enclosure - 4 8" L7 Subs - Level 4': 52 x 16 x 16 in (as printed; axes not labelled), fits 2009+ F-150 crew cab, requires a 1" seat lift. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: Ground Shaker 'BLACK 12" DUAL SEALED SUB BOX, FITS 01-23 FORD F-150 CREW-CAB': Front Height 8 1/2", Rear Height 5", Length 44", Depth 12 1/4" (labelled by Ground Shaker), 1.35 Cubic Ft., under rear seat; Ground Shaker 'BLACK 8" SINGLE SEALED SUB BOX, FITS 09-26 FORD F-150 CREW-CAB': Front Height 7 1/4", Rear Height 5 1/4", Length 23 3/4", Top Depth 13 3/4", Bottom Depth 11" (labelled by Ground Shaker), 0.57 FT^3, under rear seat.

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 size	6x8" (Standard Cab/SuperCab) — one forum source claims 5x7" for a 2014 SuperCrew, an unresolved discrepancy. Confirmed on Sony-equipped trims: speakers exist in all four doors as part of the full system (see tweeter below for the A-pillar-specific component).
Known obstructions	Confirm cab-style-specific size before recommending a swap — the 6x8" vs 5x7" discrepancy may reflect a real cab-style difference
Adapter bracket needed	unconfirmed
Tweeter	Front pillar (A-pillar), not the door itself. Specific, asymmetric removal procedure confirmed: driver's side requires pulling down the door gasket and prying the plastic trim; passenger side requires removing the pillar pull handles first — a genuinely different procedure per side, not a mirror-image job.

Rear doors Solid

Factory speaker size	6x8" (Standard Cab/SuperCab pattern) — SuperCrew-specific rear size not independently confirmed
Known obstructions	None specifically documented
Adapter bracket needed	unconfirmed
Tweeter	n/a — this system's tweeter is front A-pillar only, not doubled to rear

Factory audio integration

Factory amp / premium audio	Sony premium audio was available on some trims this generation (matches the note already in the 2015-2020 page about the Sony-to-B&O transition happening later). Complete breakdown confirmed: 1 dash-center channel, 2 A-pillar tweeters (1.646", 4-ohm), speakers in all four doors, and the sub under the rear seat. Ford's 2012 brochure, Lariat: 'Load up to 6 CDs in the 10-speaker, 700-watt Sony Audio System'; 2013 brochure: 'Audio System from Sony with HD Radio and single-CD player'. UNRESOLVED: the breakdown above (dash centre, 2 A-pillar tweeters, four doors, one sub = 8) does not reach Ford's 10, so either a speaker is missing from the breakdown or the 10-speaker Lariat system is a higher tier than the one described. A retailer's Sony upgrade kit listing for 2009-2014 SuperCab and SuperCrew calls the Sony base system '7 speaker'.
Adding subs without a head-unit swap	Confirmed straightforward — extensive direct-fit and semi-custom product ecosystem exists
Head unit	No replacement needed

Known integration products

JL Audio Stealthbox (multiple configs, see below)
Kicker SF150C09 powered subwoofer upgrade - Kicker's own wording: 'Designed for 2009 - 2014 Ford F150 Super-Crew vehicles (not compatible with 2009-2010 trucks that have Sony Factory Premium Audio)'. Kicker PF150C11: 'Designed for 2011 - 2012 Ford F-150 Crew-Cab vehicles with base radio and 2013 - 2014 Ford F-150 Crew-Cab vehicles with non MyFord Touch radios'.
PAC AmpPRO AP4-FD11 and AP4-FD21 ("Ford Sony System Amplifier Interface") - NET Audio lists both for 'Ford F150 (2009-2014)'; PAC's AP4-FD21 manual: 'only compatible in vehicles equipped with a data bus controlled premium sound system. To verify compatibility, look for a Sony badge on the door speakers, center speaker, or factory sub woofer.'

Very well documented — multiple direct-fit commercial products. Kicker's L7T dual-10" enclosure (51KFDL7T102) is sold as fitting F-150 Crew Cab 2009-2026 — spanning THIS generation plus both later ones (2015-2020, 2021-2024). Strongly suggests SuperCrew underseat geometry stayed consistent across three full generations. Worth treating as a working hypothesis, not yet independently confirmed by measurement.

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.
