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.

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 | 6-3/4" (6.5" also fits without major issues per real owner reports) |
|---|---|
| Max mounting depth | 3.5 in |
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a in the doors — real, genuinely trim/config-dependent DASH tweeter location confirmed: 2020-2023 (pre-refresh) non-external-amp trims mount the tweeter in the CENTER dash; trims WITH an external amp instead mount it in the OUTER dash corner. 2024-2025 (facelift) trims moved to outer-dash mounting universally, regardless of amp configuration — a real, confirmed running change at the mid-cycle refresh. Exact diameter not confirmed. |
| Factory speaker size | 6-3/4" (same as front) |
|---|---|
| Max mounting depth | 3.5 in |
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is dash mounted, front only |
| Factory amp / premium audio | Real, confirmed throughout this entry's full span with a genuine mid-cycle spec upgrade. Bose 12-speaker system available across 2020-2024. Real refinement within the span: the 2024 model year added Bose CenterPoint 360 processing — a real DSP/software upgrade, not just a rebadge, similar in kind to the Super Duty B&O amplifier-spec change found on other vehicles covered here. Exact trim gating (which Sonata trim gets Bose) not independently confirmed. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit |
| Head unit | No replacement needed |
Real full spec: mounting hole cutouts 7.125"/9.125"/11.125" for 8"/10"/12", 7.75" mounting depth, 0.90 ft3 airspace per sub/chamber.

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.
