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: SuperCrew (only cab style offered)
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | underseat, both cubby holes |
|---|---|
| Outer bounding box | Real owner-measured (not official factory spec, but real physical measurements): roughly 17"L (stops at a bulge in the middle back corner) x 12"W x 8.5-9"H (accounting for a hump in the middle of each cubby) |
| Known obstructions | Confirmed irregularity: a bulge/hump in the middle of each cubby hole reduces usable space from the raw outer dimensions — consistent with this being a compact, non-rectangular cavity |
| Usable volume estimate | 0.65 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" sealed, 0.45 ft3 |
|---|---|
| Box type | sealed |
| Location | under rear seat, direct drop-in |
| Subwoofers | 1x10" fiberglass, 0.65 ft3 |
|---|---|
| Box type | sealed |
| Location | under rear seat |
Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.
| Factory speaker size | 6-3/4" — consistent across both base and Bang & Olufsen-equipped systems |
|---|---|
| Known obstructions | Requires removing the door panel to access; aftermarket 6-3/4" replacements need the inner tabs on their mounting bracket removed to install |
| Adapter bracket needed | no |
| Tweeter | Dash corners, not the front doors themselves — confirmed common location across both audio systems. |
| Factory speaker size | n/a — IMPORTANT CORRECTION found: this cab's rear speakers are NOT door-mounted at all. They're located BEHIND the 2nd-row seats (confirmed via Ford Authority reporting specifically on this placement), a genuinely different location than a typical rear door speaker. Confirmed size at that location: 4", two-hole mount. |
|---|---|
| Known obstructions | Not door-mounted — see other speaker locations for the actual rear speaker location/size |
| Adapter bracket needed | n/a |
| Factory amp / premium audio | Confirmed base-vs-B&O split with a real plug-and-play harness product specifically for the non-amplified base system, matching the pattern already confirmed on the sister F-150 pages. Ford's MY2024 order guide: the XL lists "AM/FM Stereo w/ 6 Speakers"; "B&O Sound System by Bang & Olufsen 8-Speakers including Subwoofer" is in the Lariat standard-equipment list (XLT and option-package rows were not read for a B&O option). |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — direct drop-in products exist |
| Head unit | No replacement needed |
Specific products: single 10" fiberglass enclosure (22"L x 12"W x 7.5"H, 6.5" mounting depth, 9" cutout, 0.65 ft3); 8" sealed (7.125" cutout, 0.45 ft3, 6" mounting depth, 7.5"H x 18.5"L x 10.75"W); 10" sealed (9.375" cutout, same 0.45 ft3 and overall footprint). Direct drop-in, no plastic removal needed — genuinely easy install compared to most trucks. CAVEAT: subwoofers with wide baskets or oversized magnets may not fit the compact cavity — driver selection matters more here than on the full-size trucks.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.

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.
