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: SuperCab, SuperCrew
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | under passenger-side rear seat, SuperCrew only |
|---|---|
| Outer bounding box | Confirmed real factory storage bin location exists (JL Stealthbox replaces it directly) and real Goose Gear seat-delete product line exists for this generation — specific outer dimensions not found, inferred lower bound from the ProLine-X (1.3 ft3) and Skar (1000W-rated single 10") products already in this entry |
| Known obstructions | None specifically documented |
| Usable volume estimate | 1.3 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.

|---|---|
| Box type | sealed |
| Location | under rear seat |
| Subwoofers | 1x10" loaded, 1.3 ft3 |

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 | 2019-2023 (5th Gen): compatible with 6.5"/6.75" aftermarket, suggesting a similar factory size. 2024-2025 (6th Gen, new platform within this entry's year range): confirmed 6x9", with tweeters relocated to the pillars. |
|---|---|
| Known obstructions | Real generation split within this entry's range — don't assume 5th and 6th gen share the same door speaker size |
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar (2024-2025 6th Gen, B&O system only). 5th Gen (2019-2023) tweeter integration/location not independently confirmed. |
| Midrange | n/a — door itself functions as the midbass driver on the component system, woofer handles lows/mids, tweeter takes over above ~3kHz |
| Factory speaker size | 2019-2023: 6.75" (SuperCab and SuperCrew both). 2024-2025: 6.5". |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter (2024-2025 B&O) is front A-pillar only, not doubled to rear |
| Factory amp / premium audio | B&O system confirmed on equipped trims with a factory ~6" driver behind the rear seats |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — multiple direct-fit products exist for SuperCrew specifically |
| Head unit | No replacement needed |
Real specific products: Skar Audio single 10" loaded, 1000W, seamless fit below rear seat, up-firing design (preserves cabin space). JL Audio Stealthbox: 10TW1-2, 300W, 2-ohm mono, installs under passenger-side rear seat in place of the factory storage compartment — EXPLICITLY WILL NOT FIT SuperCab, SuperCrew only. ProLine-X: 1.3 ft3, up to 1000W RMS, seat removal is 4 bolts / 25-30 min with basic tools. B&O-equipped trucks have a factory ~6" driver behind the rear seats.
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.
