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
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 | 40"W x 17"H x 29"-37"D |
| Known obstructions | None specifically documented for this generation. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | keep/upgrade the factory dual 9" Bose subwoofers |
|---|---|
| Box type | n/a — factory dual-driver system |
| Location | trunk, factory location |
| Subwoofers | 1x10" or 1x12" pre-built, quick-disconnect mount |
|---|---|
| Box type | pre-built, detachable |
| Location | trunk — real confirmed generous depth range up to 37" |
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 | Real, generation-specific flexibility confirmed: front doors on this generation accommodate 6x9", 6x8", OR 6.5" aftermarket speakers — an unusually wide range of compatible sizes for one factory door opening. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | 6.5" (Bose-equipped trims, confirmed as part of the full system breakdown below). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter (Bose trims) is A-pillar mounted, front only |
| Factory amp / premium audio | Bose premium system (this generation, confirmed via a real, specific forum breakdown): 3x 4" dash speakers, 2x 6x9" front door speakers, 2x 6.5" rear door speakers, and TWO 9" SUBWOOFERS — a genuinely substantial factory system with dual large subs, distinct from a much older Bose spec (2000-2008-era Maxima) that used smaller 6x9" rear-deck subwoofers requiring significant seat/deck disassembly to access — do NOT conflate the two; that older spec belongs to a different, earlier generation not covered by this entry. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via real forum discussion of impedance-matched Bose speaker replacement projects — a documented, careful approach that accounts for the Bose system's electrical characteristics rather than a blind swap. |
| Head unit | No replacement needed |
Real, specific cargo dimension confirmed: 40"W x 17"H x 29"/37"D available for a subwoofer enclosure — a genuinely large trunk depth range for a sedan. Real owner-documented approach: pre-built subwoofer units installed with quick disconnects specifically for cargo flexibility, the same detachable-mount philosophy already confirmed on several other vehicles covered here (GV70/G80, Range Rover Sport).
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.
