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 | factory sub+amp location |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the real factory sub+amp part's own footprint is the best available reference point. |
| Known obstructions | None specifically documented. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | keep/replace the factory sub+amp combo (Limited trim, sourceable OEM part) |
|---|---|
| Box type | n/a — factory location |
| Location | factory sub location |
| Subwoofers | 1x10" or 1x12" sealed, custom-built |

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 | 6x8" (oval), 4-ohm, 2-way midrange — confirmed via a named OEM replacement part (6U5T18808EA). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar — confirmed by Ford's 2009 and 2010 brochures ('A-pillar-mounted tweeters') as part of the Premium Sound System (9 speakers including an 8" subwoofer, 320 W): standard on Limited, optional on SEL and Sport. SE and SEL cars with the standard 4-speaker system (2008 spec page) do not have this tweeter or the front subwoofer wiring. |
| Midrange | n/a — the door speaker itself is already a 2-way midrange unit |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — this generation's tweeter is A-pillar, not doubled to rear doors |
| Factory amp / premium audio | Ford's own 2007-2010 documents do not call this system Sony. 2008 spec page: SE 'Premium AM/FM/Single CD/MP3 capable audio system and 4 speakers', SEL 'Premium CDx6 with 4 speakers', Limited 'Audiophile sound system with 9 speakers'. 2009 and 2010 brochures: the Limited carries a 'Premium Sound System' with a 6-disc changer and '9 speakers (including A-pillar-mounted tweeters and an 8" subwoofer) with 320 watts', optional on SEL and Sport. The 2007 spec page instead lists 'premium CDx6 with 9 speakers' on the SEL with an SEL-only 'audiophile sound' option, so Ford's 2007 and 2008 pages disagree about which trim carried the 9-speaker system. The A-pillar tweeters and the 8" subwoofer are confirmed; Ford's first Sony mention for the Edge is the 2011 brochure ('a new 390-watt Audio System from Sony'). The 2026-07-22 text here said a Sony Audiophile system was available on 2007-2010 Limited trims and that the factory sub and amp belong to it. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward via named replacement speaker/amp bundles designed as drop-in solutions. |
| Head unit | No replacement needed |
Specific factory finding: 2007-2010 Edge Limited trims came equipped with a genuine factory-installed subwoofer+amplifier combo — confirmed as a sourceable used-market replacement part. CROSS-MODEL NOTE: at least one real parts listing bundles this exact sub+amp part as fitting '2008 2009 2010 2011 Ford Edge Escape' together — a real hint that this generation's Edge may share this specific audio component with the contemporary Ford Escape, though not independently confirmed as a full platform-sharing case.

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.
