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 (EV)
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | frunk (front) AND rear trunk — a genuinely different structure from every ICE vehicle, two separate real cavities rather than one |
|---|---|
| Outer bounding box | Frunk: 12.4"D x 25.4"W x 9.7"H, 3.1 ft3. Rear trunk: real source disagreement on the exact figure — 15 ft3 (one source) vs. ~19.8-20 ft3 combined-with-frunk (another) — recorded as disagreement rather than averaged, consistent with our rule for conflicting sources. With rear seats folded: ~43 ft3. |
| Known obstructions | No traditional engine bay — the frunk exists specifically because there's no engine there. A build here means choosing which cavity (or both) to use, not finding room in a single trunk. |
| Usable volume estimate | 15 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" sealed, 1.35 ft3 config |
|---|---|
| Box type | sealed |
| Location | rear trunk/sub-trunk area |
| Subwoofers | 1x10" or 1x12" ported, tuned 33Hz |
|---|---|
| Box type | ported |
| Location | rear trunk/sub-trunk area |
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 | 6.5" woofer (Premium 15-speaker system: 2 amps, 5x 1" tweeters + 7x 3.5" midrange + 2x 7" woofers total across the vehicle + 1x 8" dual-coil subwoofer) — real, confirmed via a detailed community teardown (travisllado.com). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Real, genuinely nuanced location found: the OEM tweeter pods sit at the FRONT EDGE of the front door panel, just behind/underneath the A-pillar — some sources describe this simply as 'A-pillar mounted,' others as door-edge-mounted immediately adjacent to the A-pillar. Not the same door-triangle location confirmed on the Model Y entry (see that entry's tweeter note) — a real, genuine cross-model difference within the same brand. |
| Midrange | n/a — real, confirmed all 3 midrange units (3.5" each) are DASH-mounted (accessed by pulling A-pillar covers and the full-width dash speaker grille bar), not door-mounted. |
| Factory speaker size | the 15-speaker breakdown found accounts for tweeters/midrange/front-door woofers/subwoofer, but no rear-door-specific driver was independently confirmed. |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Factory system is fully digital/amplified, no traditional head unit — all EVs in this category share this trait |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward for the box/mounting itself, but see the critical electrical note below — this is NOT the same as a gas-car LOC tap. |
| Head unit | No replacement needed |
Real, active build community — this is NOT a niche request, Tesla Motors Club has extensive dedicated threads. Factory subwoofer enclosure baseline: 0.76 ft3 (21.5L), 2.36" port diameter, 7.2" port length, tuned ~42Hz — a real factory reference point rare to have this precisely documented. Commercial sealed mono-chamber box: 1.35 ft3, cutouts for 8"/10"/12" (7.00"/9.00"/11.00"), 9.00" mounting depth. Ported version same footprint, tuned 33Hz. DIY builds commonly hit 1.75-2 ft3 depending on material thickness (27.125"x16"x9.625" at 3/4").

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.
