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.
| Location | rear deck (Bose-equipped trims) |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — only the confirmed 6x9" driver size and the real access-difficulty note. |
| Known obstructions | Significant rear-seat/deck disassembly required to access the factory subs on Bose-equipped trims. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" powered, general trunk install (non-Bose trims — simpler access than the Bose rear-deck units) |
|---|---|
| Box type | n/a — powered unit |
| Location | trunk |
| Subwoofers | keep/upgrade the factory rear-deck 6x9" Bose subs, accepting the real, more involved disassembly required |
|---|---|
| Box type | n/a — factory rear-deck system |
| Location | rear deck |
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 | 6x9" (non-Bose trims) plus a separate 1" front tweeter — real, specific breakdown distinct from the Bose-trim spec. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Front door-mounted (non-Bose trims) — real, confirmed 1" tweeter alongside the 6x9" woofer in the same door. Bose-equipped trims route rear-channel bass through rear-deck 6x9" subs instead — whether Bose trims ALSO get a front door tweeter is not independently confirmed, flagged rather than assumed. |
| Factory speaker size | 5.25" on Bose-equipped models; 6.5" on non-Bose models — a real, specific, GENUINELY INVERTED size relationship worth flagging: the premium (Bose) trim actually uses a SMALLER rear door speaker than the base trim, likely because more of the Bose system's rear-channel output is carried by the rear-deck subwoofers instead. Don't assume 'premium trim = bigger speakers everywhere.' |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — no confirmed rear-door tweeter on either trim |
| Factory amp / premium audio | Bose premium system (available trims): 6x9" rear-deck subwoofer pair, 5.25" rear door speakers (smaller than the non-Bose trim's rear doors, see above). Non-Bose trims: 6x9" front door + 1" front tweeter, 6.5" rear door. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via multiple real forum threads specifically about replacing/upgrading the Bose speakers on this era, including at least one real impedance-matched replacement project write-up. |
| Head unit | No replacement needed |
Real, specific factory finding: Bose-equipped trims of this era include a pair of 6x9" subwoofers mounted in the REAR DECK — a genuinely different factory approach from the 8th Gen (2016-2023) entry's own dual-9" trunk-mounted Bose subs already; do NOT conflate the two, they belong to different generations with different real specs. A real, specific access difficulty: reaching these rear-deck subs requires significant disassembly of the rear seat and deck area — a genuinely more involved job than a typical trunk-mounted sub swap.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.

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.
