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 Sedan, 2-Door Coupe
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | trunk |
|---|---|
| Outer bounding box | No independently measured trunk dimensions found. Published box footprints are lower bounds on the cavity, not the cavity: SRQ Customs 'HONDA ACCORD 2008-2012 SUB ENCLOSURE' and 'DUAL SUB ENCLOSURE': 40 x 18 x 12 in (as printed; axes not labelled), 1.4 cu.ft, under the rear deck against the back of the rear seat, room for an amplifier up to 21 in wide; Ground Shaker 'BLACK 10" DUAL SEALED SUB BOX, FITS 94-25 HONDA ACCORD': Height 13 1/2", Front length 37 1/4", Rear length 31 1/4", Top depth 13 1/2", Bottom depth 17 3/4" (labelled by Ground Shaker), 3.15 ft^3 total. Zenclosures and Super Crew Sound print no outside dimensions (amp area 2.75 in tall x 20 in wide under the box). |
| Known obstructions | None documented for this generation. |
| Location | trunk |

| Outer bounding box | No independently measured trunk dimensions found; the same published box footprints as the sedan trunk (the makers do not split them by body style). |
| Known obstructions | None documented for this generation. |
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 | Honda's 2008-2012 pages read give speaker counts and watts, not door sizes |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Honda: standard 160 watts, single-disc CD, six speakers (LX, LX-P, SE sedans); 160-watt 6-disc in-dash changer, six speakers (Sedan EX and EX V-6, Coupe LX-S); premium 270 watts with a 6-disc changer and seven speakers including an 8-inch subwoofer on the Sedan EX-L and EX-L V-6 and the Coupe EX and EX-L (2009 release, 2012 specification page). Honda's 2008 pages word the trims differently: its 2008 introduction names the premium system for "EX-L and V-6 models", its 2008 launch release for "EX Coupe and Sedan EX-L". So a factory subwoofer exists on the EX-L sedans and the EX/EX-L coupes. |

Honda: 14.0 cu ft sedan trunk (2008) and 14.7 (2012). A luggage rating, not box dimensions. No measured width, height or depth was found. Zenclosures and Super Crew Sound boxes slide in below the rear dash and offer an amp area under the box 2.75 in tall x 20 in wide; SRQ boxes sit under the rear deck against the back of the rear seat.
Honda: 11.9 cu ft coupe trunk (2008 and 2012). A luggage rating, not box dimensions. No measured width, height or depth was found.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.
Each link opens the tool with this vehicle already selected.
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.
