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

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 | 2006-2013: 5.25"/6.5"/6.75" compatible, but real mounting depth constraint of only 2.9" — not a simple plug-and-play swap. 2014-2016: 6x9" factory, compatible with same-size, 6.5", or 6.75" aftermarket. |
|---|---|
| Max mounting depth | 2.9 in |
| Known obstructions | 2006-2013's 2.9" depth ceiling is the binding constraint for the older generation — genuinely shallower than the 2014-2016 generation |
| Adapter bracket needed | unconfirmed |
| Factory speaker size | unconfirmed for either generation |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Bose Centerpoint Surround Sound premium 11-speaker system confirmed (Bose-equipped trims): 2.5" dash-mounted 'Twiddler' mid/high speakers, A-pillar tweeters (tight cavity), and rear-deck 6x9"+3" tweeter — a real, genuinely multi-location tweeter architecture spanning three separate spots rather than one. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit |
| Head unit | No replacement needed |
Real measured trunk space: 36"W x 17"H x 40"D (front and back). Fits up to 2x12" or 3x10" sealed. Builders commonly tune ported boxes deep (34-37Hz) on this platform, consistent with its historical association with deep-bass/SPL trunk builds. Custom builders (AK Audio, SubThump, Sound Off Audio) all offer generation-specific products, pricing starting around $700 for built-to-order enclosures.
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.
