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 Crossover
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | passenger-side rear cargo wall |
|---|---|
| Outer bounding box | 8" factory subwoofer in a sealed enclosure — exact external dimensions not independently measured. |
| Known obstructions | None specifically documented beyond the factory enclosure's own built-in-wall location. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | keep/replace the factory Sony sub assembly (real, sourceable OEM part) |
|---|---|
| Box type | n/a — factory location |
| Location | passenger-side rear cargo wall |
| Subwoofers | 1x10" or 1x12" powered addition via the real named PAC APSUB-FD21 integration module |
|---|---|
| Box type | n/a — powered unit, factory-databus-tap wiring |
| Location | cargo area |
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 | 5x7" midbass driver (Sony-equipped trims) — real, confirmed as part of the complete 12-speaker system breakdown. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Midrange | n/a — door speaker is a dedicated midbass driver, dash/D-pillar handle the rest |
| Factory speaker size | 5x7" midbass driver, same as front — real, exact removal procedure confirmed (see cargo_fitment notes). |
|---|---|
| Known obstructions | Multi-step removal: grab-handle cover, 5.5mm screw, two Phillips screws, screw-cap cover + Phillips screw, panel unclip, window-switch-harness unclip. |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — this system's tweeter is front A-pillar only, not doubled to rear |
| Factory amp / premium audio | REAL, CONFIRMED SONY-BRAND BOUNDARY: this is exactly the generation where Sony became the Edge's premium-audio partner (matching the boundary already flagged as likely in the 2007-2010 entry) — a real, complete, named 12-speaker/390W system: 2x A-pillar tweeters, 1x dash center speaker, 2x door midbass (5x7"), 2x D-pillar speakers, and the 8" sealed-enclosure subwoofer described above. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a real, named integration product: the PAC APSUB-FD21 amp-installation module, which includes a Ford-specific wiring harness and a wired remote — the harness connects to the factory databus and supplies an UNEQUALIZED 5-VOLT preamp signal for a new sub amp, a real, specific, exact signal spec worth knowing rather than assuming a generic line-level output. |
| Head unit | No replacement needed |
Real, specific, complete factory location confirmed: the factory 8" subwoofer sits in a SEALED enclosure built into the passenger-side wall of the rear cargo area — a real, precise location distinct from the 2007-2010 entry's less-specific sourcing. Real, exact door-panel removal procedure confirmed for accessing the rear doors: unplug the cover behind the grab handle, remove a 5.5mm screw, remove two Phillips screws on the bottom of the door panel, remove a screw-cap cover and its Phillips screw, unclip the door panel, then unclip the window switch harness before the panel comes free.
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.
