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, through existing opening (body-style-specific) |
|---|---|
| Outer bounding box | Sedan max: 35"W x 17.5"D x 18"H (will NOT clear 6x9 speakers or factory amp). Coupe: 32"x17"x17" (WILL clear both) |
| Known obstructions | Sedan's factory 'black box' amp physically blocks larger builds — opposite of the usual sedan-vs-coupe pattern, verified per source |
| Usable volume estimate | 1.5 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" sealed |
|---|---|
| Box type | sealed |
| Location | trunk — confirm coupe vs. sedan clearance before finalizing size |
| Subwoofers | 1x12" sealed |
|---|---|
| Box type | sealed |
| Location | trunk, coupe body style has more usable clearance per the real fitment guide found |
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" woofer + 3" tweeter (real 2-way factory setup) |
|---|---|
| Known obstructions | 6/7-speaker systems have sail panel tweeters; 4-speaker versions do not |
| Adapter bracket needed | unconfirmed |
| Tweeter | SAIL PANEL-mounted (not in the door itself, not dash/A-pillar) — real, confirmed, 6/7-speaker systems only; 4-speaker base systems have no tweeter at all. |
| Factory speaker size | 6.5" (real aftermarket product confirms this via a dedicated speaker pod) |
|---|---|
| Known obstructions | Coupe body style has speakers in doors and rear deck instead of true rear doors |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is sail-panel mounted, front only |
| Factory amp / premium audio | A factory amp ('black box') is confirmed present on at least some trims — real, specific obstacle for sedan-body installs per the fitment note above |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit, though the factory amp module itself is a physical clearance obstacle on the sedan body style |
| Head unit | No replacement needed |
REAL BODY-STYLE-SPECIFIC FITMENT DIFFERENCE, worth keeping distinct rather than treating 'Accord' as one shape: Sedan max external box dimensions are 35"Wx17.5"Dx18"H but will NOT clear the 6x9 speakers or the factory 'black box' amp; Coupe dimensions are smaller (32x17x17) but WILL clear both. This is the opposite of the usual pattern (coupe usually has less room) — worth double-checking, but that's what the source states. Mounting hole cutouts: 9.125" (10") / 11.125" (12").
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.
