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: Minivan
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | cargo area behind the third row (third-row seat folds into the floor) |
|---|---|
| Outer bounding box | No cargo dimensions in inches found for this generation. Maker-published, not a measured usable cavity: Honda's 2005 interior release says the flat floor "can accommodate 4x8 sheets of building materials". A capability statement, not a measured width; the seat position it assumes is not given here. |
| Known obstructions | Third-row seat folds into the cargo well (Honda 2005 interior release); the well and seat are the same space. |
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 | Touring (Honda 2005): "the four front and rear speakers are a 17cm Kevlar- injected polypropylene mid-range speaker." (17 cm = 6.69 in by conversion; the sentence names front and rear speakers without saying doors). LX and EX sizes not stated. |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory speaker size | Touring (Honda 2005): the same 17 cm mid-range speaker as the front ("four front and rear speakers"); whether the rears are in the sliding doors is not stated. LX and EX sizes not stated. |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Honda, by trim (no brand name printed). 2005 interior release: LX "AM/FM stereo radio with a CD player and an auxiliary input (four speakers, 120 watts)"; EX adds a six-disc in-dash changer; Touring "a 360-watt amplifier and a total of seven speakers (including a subwoofer)". 2010 specification rows: LX "120-Watt AM/FM/CD Audio System with 4 Speakers"; EX and EX-L "120-Watt AM/FM//6-Disc In-Dash Audio System with 6 Speakers"; Touring "360-Watt AM/FM/6-Disc In-Dash Premium Audio System with 7 Speakers including Subwoofer" (the page text is flattened; trim columns inferred from marker positions). 2006-2009 not read. |

Honda 2005 interior release: "The cargo area behind the third row seats provides 38.4 cu. ft. of storage." Honda 2010 specification rows (all trims): "Cargo Volume (cu ft, behind 3rd-row)" 38.4; "behind 2nd-row" 91.1; "behind 1st-row" 147.4. Honda 2005 also says the flat floor "can accommodate 4x8 sheets of building materials" (a capability statement, not a width). No cargo length, width, height or opening in inches. No SAE or EPA label printed. No box made for a 2005-2010 Odyssey was found from the box makers checked.

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.
