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: Pickup Truck
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | behind the rear seat |
|---|---|
| Outer bounding box | sized for dual 10" subwoofers (TacoTunes System 1B spec) on gas trims |
| Known obstructions | i-FORCE MAX hybrid battery pack meaningfully reduces available space in this same area — hybrid trims need a dedicated hybrid-specific enclosure, not the standard gas-trim product. Standard install (both gas and the hybrid-capable version) shifts the rear seat forward ~1 inch via included brackets. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | TacoTunes add-a-subwoofer harness + powered compact sub (gas trims) |
|---|---|
| Box type | plug-and-play, self-powered |
| Location | behind rear seat |
| Subwoofers | TacoTunes System 1B dual 10" complete system (gas) or Fox Acoustics hybrid-capable enclosure (i-FORCE MAX) |
|---|---|
| Box type | turnkey, sealed |
| Location | behind rear seat |
Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.
| Adapter bracket needed | unconfirmed |
|---|---|
| Tweeter | Dash-corner tweeters on non-JBL trims — real, confirmed 3 dash speakers total (corners + center) on this generation, exact tweeter-element diameter not independently confirmed. JBL-equipped trims instead use a true A-pillar tweeter (100W RMS per real forum sourcing), with owners specifically buying factory JBL A-pillar assemblies for tweeter upgrades — consistent with the recurring Toyota-wide dash-vs-A-pillar split confirmed on other vehicles covered here (RAV4, Highlander). |
| Adapter bracket needed | unconfirmed |
|---|---|
| Tweeter | n/a — tweeter is dash/A-pillar mounted, front only, unlike the sibling 2nd Gen (2014-2021) entry which has a real rear-door tweeter. Genuinely different architecture across the 2022 full redesign, not assumed to carry over. |
| Factory amp / premium audio | JBL confirmed as the factory premium system on equipped trims — real, dedicated commercial product lines exist specifically naming '2022+ JBL EQUIPPED Toyota Tundra,' confirming JBL availability and real aftermarket demand for this exact generation. |
|---|---|
| Adding subs without a head-unit swap | Confirmed, genuinely easy on gas trims — plug-and-play harnesses (both a standard signal-tap version and a 'pre-JBL amp signal, unmodified' version for more control) exist, no cutting or splicing required. Hybrid trims are more constrained per the caution above. |
| Head unit | No replacement needed |
Real, full redesign confirmed for this generation, introducing the i-FORCE MAX hybrid powertrain option. TacoTunes has a dedicated 'System 1B' complete audio system plus add-a-subwoofer packages specifically for this 2022+ JBL-equipped Tundra CrewMax — real, named commercial products, dual 10" subwoofers at 800W RMS, plug-and-play with stock mounting locations and no drilling/cutting. **Real, important hybrid caution**: the i-FORCE MAX hybrid's battery pack genuinely constrains cargo space behind the rear seat — real forum sourcing describes standard enclosure options as 'few and very limited' for hybrid trims specifically, though Fox Acoustics has released a real, named hybrid-capable enclosure as a solid alternative. This matches our standing hybrid-caution pattern (verify battery footprint case by case) — treat hybrid trims as constrained-but-not-fully-excluded, not identical to the gas trims' full compatibility.

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.
