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.

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 | genuinely unusual 5.8" factory driver + 1.3" tweeter (not a standard round size) — real aftermarket options include 6.75"/6.5" with brackets/minor modification |
|---|---|
| Known obstructions | Non-standard factory size means most drop-in replacements need modification |
| Adapter bracket needed | yes |
| Tweeter | Originally dash-mounted per real forum sourcing — exact dash position (corner vs. center) not fully pinned down. A real, genuinely unusual 1.3" size, matching the non-standard 5.8" door driver as part of the same odd-sized factory system. |
| Factory speaker size | unconfirmed |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — tweeter is dash mounted, front only |
| Factory amp / premium audio | Real, trim-gated, with a confirmed spec detail for the current model year. Harman Kardon premium audio available on the GT trim via the GT2 package for 2019-2021 (BD generation). For 2024 specifically: 8-speaker Harman Kardon standard on GT Manual, optional via GT-Line Premium Package or GT2 Package on other trims. 2022-2023 not independently re-confirmed, though likely consistent with both ends of this range. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit |
| Head unit | No replacement needed |
Real specific spec: 8" mounting depth, cutouts 11.125"(12")/9.125"(10")/7.125"(8"), 0.98 ft3 airspace per chamber. Earlier generation (2014-2018) cargo: 16"H x 41"W x 39"/32"D. Real pricing data: pre-made Zenclosures box $239.99; a complete professional installation (amp, sub, sealed enclosure, wiring, install, line converter) ran under $1,300 CAD.

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.
