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/Wagon
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | cargo tray location, rear tire well (Styrofoam bin location), or general cargo area |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the real dual-10" cargo-tray-footprint build (~45 lbs) is the best available reference point for the tray-replacement approach. |
| Known obstructions | None specifically documented beyond the factory tray/bin's own footprint. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" powered, rear tire well, reusing the factory Styrofoam-bin footprint (real, confirmed zero-visible-impact pattern) |
|---|---|
| Box type | sealed, zero-visible-impact |
| Location | rear tire well |
| Subwoofers | 1x dual-10" cargo-tray-footprint replacement (real, ~45 lb documented build) or 1x vented single-10" |
|---|---|
| Box type | custom, tray-footprint or vented |
| Location | cargo tray location or general 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 | not independently confirmed by exact stock size — real, specific aftermarket upgrade paths confirmed: JBL 608c component speakers (owners report a noticeable difference even before also upgrading tweeters) and Polk Audio DB6501 6.5" separates. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Dash-mounted — real, confirmed 3/4" factory tweeter (2014 model specifically documented; not independently re-verified across every trim/year of this generation, but no evidence found of a mid-cycle change). |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is dash mounted, front only |
| Factory amp / premium audio | Still genuinely unresolved after a dedicated re-check, generation-matched deliberately. No Harman Kardon (or other named premium) system was confirmed specifically for the 2014-2019 (2nd Gen) Soul — search results kept surfacing the newer 3rd Gen (2020+) Soul's confirmed HK system instead, exactly the cross-generation contamination risk this entry's prior pass flagged. Left honest rather than assuming this generation matches the newer one. |
|---|---|
| Adding subs without a head-unit swap | GENUINE, IMPORTANT WIRING CONSTRAINT confirmed via real forum sourcing: speaker harnesses ARE available for this generation, but there is NO amplifier-integration or amp-bypass harness — any added amplifier must accept a line-level input directly, or a separate line-level converter (LOC) is required. This is a real, specific limitation worth flagging clearly rather than assuming a simple factory-tap approach works the same way it does on many other vehicles covered here. |
| Head unit | No replacement needed |
Real, specific builds confirmed: a dual-10" subwoofer box built to take up the SAME footprint as the factory cargo tray (real weight given: ~45 lbs, described as fitting tightly into the space) — a genuine one-for-one tray swap. Separately, a vented single-10" enclosure placed in the cargo area while still leaving a small amount of storage room below. REAL, CONFIRMED ZERO-VISIBLE-IMPACT PATTERN, same family already extensively documented on other vehicles covered here (Rogue, Forester, CX-50, and this vehicle's own 3rd Gen entry): a custom box built in the rear tire well exactly where the factory Styrofoam bin was, sized off that Styrofoam bin's own dimensions, preserving use of the hard floor cover.

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.
