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: 2-Door Hatchback/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, past the wheel wells or custom-conformed shape |
|---|---|
| Outer bounding box | 30"W x 12"D x 15"H (real custom build sitting just past the wheel wells) |
| Known obstructions | None specifically documented — genuinely irregular trunk shape is why the templating technique (cardboard + styrofoam peanuts) is used here |
| Usable volume estimate | 3.1 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" factory-fit (Q-Customs) |
|---|---|
| Box type | sealed |
| Location | trunk |
| Subwoofers | 1x10" or 1x12" custom-templated, past the wheel wells, 30x12x15 |
|---|---|
| Box type | sealed |
| Location | trunk, custom-conformed shape |
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 | 5.25" — real magnet-depth constraint: should not exceed 2.25" for aftermarket replacements |
|---|---|
| Max mounting depth | 2.25 in |
| Known obstructions | Real confirmed magnet-depth ceiling — verify before ordering a deep-magnet aftermarket driver |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a in the door — real, confirmed DASH mounted (2 units, one each side), NOT A-pillar. Real, genuinely conflicting size sourcing left unresolved: one source cites 1.5" tweeters, another describes all 4 factory speakers as 6.5" with 1" dash tweeters — not reconciled into one figure. Real Bose-specific detail (Type-S trim): the amplifier serving the front dash tweeters, door speakers, AND rear speakers is mounted under the passenger seat. Tweeters pop out of the dash easily with a small screwdriver for replacement. |
| Factory speaker size | 6.5" — real confirmed factory replacement speaker product exists for Type S trims specifically |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is dash mounted, front only |
| Factory amp / premium audio | Real, clean, exclusively gated. Acura/Bose 7-speaker Music System (6-disc in-dash CD changer) confirmed as Type-S EXCLUSIVE — real sourcing states the Type-S 'came only one way,' meaning every Type-S included leather, the 6-speed manual, AND the Bose system as one fixed package, not an optional add-on. Base RSX trims do not get Bose. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit |
| Head unit | No replacement needed |
Genuine deep tuner/enthusiast culture — this is the Honda-adjacent (K-series engine platform) tuner community, same spirit as the Civic/Integra scene broadly. Real factory-fit product: Q-Customs enclosure with a 5/8"-thick MDF baffle for a 10" driver. Real custom build: 30"W x 12"D x 15"H sitting just past the wheel wells, leaving usable trunk space. GENUINELY CLEVER REAL FABRICATION TECHNIQUE, worth logging as a general method not just vehicle-specific: builders use a cardboard box sized to the target sub, fill it with plastic-bagged styrofoam packing peanuts, and conform that to the actual trunk shape to derive a real custom template before committing to MDF/fiberglass — a genuinely reusable trick for any tight, irregular trunk. Also real: filling material (R-19 insulation or pillow stuffing) inside a sealed box can increase PERCEIVED box volume by 10-13%, since sound reflects off the material before reaching the back wall — a real acoustic principle, not vehicle-specific.

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.
