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 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 | cargo area behind the rear seat |
|---|---|
| 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 | None documented in the releases read. |
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 | Hyundai's releases and model pages give speaker counts, not sizes or positions |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory speaker size | same gap as the front doors |

| Factory amp / premium audio | Hyundai, 2019 to 2021: "The 630-watt, 12-speaker new Infinity branded stereo system with an 11-channel amplifier" is "the available premium sound system" (Hyundai's 2019 overview and its February 2018 world-debut release; the 2020 model page says the same). For 2021 Hyundai lists a "New Harman-Kardon premium audio system": "A 630-watt, 12-speaker, Harman-Kardon premium audio system with an 11-channel amplifier". Hyundai's March 28, 2018 release printed 640 watts; its own model pages for 2019, 2020 and 2021 say 630. No trim is named for the premium system, no standard system or speaker count is given, and no subwoofer is mentioned. 2022 and 2023 are carry-over years with no audio statement. Speaker sizes and positions are not stated. |

| Adding subs without a head-unit swap | no vehicle-specific integration information found |
Hyundai's overview of the all-new 2019 Santa Fe (its model page), Volume Comparisons table, "2019 Santa Fe" column: "Cargo - Behind 2nd row" 35.9 and "Cargo - Behind FR seats" 71.3 cubic feet (the table's other columns are the 2018 Santa Fe Sport and the 2018 Tucson); Hyundai's March 28, 2018 release also prints 35.9. Hyundai's February 2018 world-debut table split the 2019 Santa Fe into a "2-row" column (36.6 behind the second row) and a "3-row" column (35.9, and 11.6 behind a third row); the US 2019 Santa Fe is the five-passenger model ("The five-passenger Santa Fe Sport will now be called Santa Fe"), and Hyundai's overview does not repeat the 36.6. For 2021 Hyundai says the "rear cargo area volume has increased by one-half cubic foot" and prints no new figure. Unlabelled US cubic feet. Luggage ratings, not box dimensions. Hyundai gives no cargo length, width, height or opening in inches; the rows named Length and Width describe the vehicle exterior. No box made for a 2019-2023 Santa Fe was found from the box makers checked. Measure your own cargo area 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.
