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 Subcompact Crossover
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | passenger-side rear cargo area, factory Bose sub location |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — multiple real named products (JL Audio 10" ported, Sound Ordnance 12") both confirmed to fit 'perfectly' are the best available reference points, suggesting genuinely generous available space for this vehicle's size class. |
| Known obstructions | None specifically documented beyond the factory sub's own footprint. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x6.5" shallow-depth direct replacement (real named product: Memphis Audio + 400W mono amp) |
|---|---|
| Box type | n/a — direct factory-location replacement |
| Location | passenger-side rear cargo area |
| Subwoofers | 1x10" ported (real named product: JL Audio, confirmed to fit perfectly) or 1x12" (Sound Ordnance box) |
|---|---|
| Box type | ported or sealed, per product |
| Location | cargo area |
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 | 6.5" — confirmed via real forum sourcing; a real upgrade path exists using JL Audio C2-series component speakers. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Not found despite a dedicated search — genuinely thin sourcing on the high-frequency side for this model, unlike its cargo/subwoofer side which is well-documented. Left honestly not researched rather than assumed from sibling Kia models, since tweeter presence/location varies meaningfully across this brand's lineup (see Sportage/Sorento/Telluride/Forte findings). |
| Factory speaker size | 6.5" coaxial — real upgrade path confirmed using JL Audio coaxial speakers specifically for the rear (vs. component speakers up front), a genuine front/rear product-type distinction worth keeping. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Bose premium system (available trims, e.g. SX Turbo): includes the factory subwoofer discussed above — real owner consensus rates the factory bass output as genuinely weak ('almost no presence'), a specific, sourced critique rather than a generic 'could be better.' |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a real, specific tap point: splice into the speaker wires feeding the original subwoofer at the side of the boot/hatch, then feed that signal into a Focal high-to-low converter — a documented, repeatable path that doesn't touch the head unit. |
| Head unit | No replacement needed |
Real, specific, EASY factory-sub-removal finding: the cargo-area floor slides out, and the factory Bose subwoofer comes out by removing just 3 10mm nuts and unplugging a simple connector — a genuinely low-friction starting point for a replacement, not a multi-hour teardown. Real owner consensus on the factory unit: the woofer in the hatch has 'almost no presence at all' — a real, specific, unusually blunt critique of factory bass output, meaning most owners here are actively upgrading rather than just adding to an already-decent system. Real named replacement products confirmed: a JL Audio 10" ported subwoofer 'fits perfectly' in the back, a Sound Ordnance 12" box from Crutchfield also 'fits perfectly,' and a Memphis Audio 6.5" shallow-depth sub paired with a 400W mono amp as a direct factory-location replacement.

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.
