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 | factory sub location or general cargo area |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the real Audiofrog modified-fit option and the JL Audio 8" ported box are the best available reference points. |
| Known obstructions | None specifically documented for gas trims. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | Audiofrog improved sub, modified into the factory location |
|---|---|
| Box type | n/a — modified factory-location fit |
| Location | factory sub location |
| Subwoofers | 1x8" ported (named product: JL Audio, real cargo-space tradeoff) |
|---|---|
| Box type | ported |
| 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 | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | a dedicated search found no confirmed tweeter location/size for this generation. Genuinely thin sourcing given how new this generation is. |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Confirmed: Bose, not Krell. Bose 8-speaker premium audio confirmed on the Kona Electric Limited trim, and separately confirmed on the Kona N Line (2025). Real brand transition from the prior generation: the 2018-2023 companion page's Infinity system was replaced by Bose on this generation — confirmed independently for both generations. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a current, specifically-titled '2018-2024+ Hyundai Kona 5 Channel Amp and Sub Install' video that explicitly spans both this generation and the prior one, plus a forum thread specifically asking how a subwoofer/amp install would affect warranty coverage — a genuine, practical concern worth surfacing for anyone recommending a build on a newer vehicle. |
| Head unit | No replacement needed |
Specific named-brand option confirmed: Audiofrog makes an improved subwoofer that, with some modification, fits into the factory sub location — a genuine upgrade-in-place path rather than a from-scratch build. Real alternative: a JL Audio 8" ported sub box adds minimal weight and DOES give up some real cargo space, but owners describe the resulting bass improvement as 'night and day' — a deliberate volume-vs-cargo tradeoff.
Kona Electric (2nd Gen): confirmed substantial cargo-capacity increase over the 1st Gen — 25.5 ft3 behind the rear seats, 63.7 ft3 with seats folded (vs. the 1st Gen's roughly 19.2/45.8 ft3) — a genuinely bigger and more usable EV variant, still safe/not-excluded per the same reasoning as the 1st Gen file (no spare tire, but no cargo-capacity loss either).
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.
