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 | No maker-published or independently measured cargo dimensions found (width between wheel housings, floor length, height, opening, liftover all absent from every maker document read). |
| Known obstructions | Nothing documented beyond a trunk pass-through opening that Nissan's 2007 kit mentions (no size given). |
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 | Nissan's press kits give speaker counts, not sizes or positions |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory speaker size | same gap as the front doors |

| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Nissan kits. 2007: SE-R standard "6-speaker 160-watt AM/FM/CD system"; "Available 8-speaker 340-watt Rockford Fosgate-powered AM/FM/in-dash CD6 system"; base Sentra offers a "Rockford Fosgate-powered audio system with 6-disc autochanger, 8-channel amplifier and 8 speakers"; no speaker count for the base car's standard system. 2012 (specifications dated Feb. 9, 2012): 2.0 "AM/FM/CD with 4 speakers"; 2.0 S "AM/FM/CD with 6 speakers"; 2.0 SR and SL "AM/FM/CD/USB with 6 speakers, 4.3-in. color display"; "Rockford Fosgate 340-Watt AM/FM w/ 8 speakers" optional (2.0 SL Audio Package; SE-R Upgrade packages); SE-R standard 6 speakers "(160 watts peak)". The kits mention no subwoofer. Speaker sizes and positions are not stated. |

| Adding subs without a head-unit swap | no vehicle-specific integration information found |
Nissan's 2007 and 2012 kits state a 13.1 cu ft trunk (unlabelled US cubic feet); the 2012 specification table's "Cargo" row reads 13.1 for the 2.0 / 2.0 S / 2.0 SR / 2.0 SL and the SE-R and 12.0 for the SE-R Spec V (which trim column the 12.0 sits in is not certain from the table: it may be the SE-R's). A luggage rating, not a box dimension. No trunk width, length, height or opening appears in either kit read. No box made for a 2007-2012 Sentra was found from the box makers checked. Measure your own trunk before cutting wood.
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.
