2020-2024 Tesla Model Y 1st Gen (pre-2025 'Juniper' refresh) — subwoofer box fitment

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 Crossover (EV)

Where a box actually fits

These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.

Trunk Likely

Locationfrunk (front) AND rear trunk — same two-cavity structure as the Model 3 companion entry
Outer bounding boxReal, SAE J1100-compliant-tested figures (2023-2024 models specifically): rear trunk 17.2 ft3, frunk 4.1 ft3, combined 28.6 ft3 with rear seats upright, 68.0 ft3 with rear seats folded. Real source disagreement noted, not resolved: one figure cites an 11.4 ft3 frunk, which is inconsistent with the 4.1 ft3 SAE-tested figure and every other source checked — treated as a likely error in that one source rather than a real alternate spec, but flagged rather than silently dropped.
Known obstructionsNo traditional engine bay, same frunk/trunk structure as the Model 3 companion entry.
Usable volume estimate17.2 ft³

Door speaker fitment

Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.

Front doors Likely

Factory speaker sizeexact door woofer size not found; the confirmed 14-speaker Premium system breakdown covers tweeter/midrange/cowl roles (see tweeter/midrange fields) but not a specific front-door woofer figure.
Known obstructionsNone specifically documented
Adapter bracket neededunconfirmed
TweeterFRONT DOOR TRIANGLE mounted (the door's upper-front corner, sail-panel-equivalent area) — real, confirmed 1"/25W unit. This is a genuinely different location from the Model 3 entry's tweeter, which sits at the door's front edge just behind/underneath the A-pillar — a real cross-model nuance within the same brand, not assumed identical.
Midrangen/a in the door — real, confirmed the door-triangle carries only the tweeter; a separate 2.5"/2W midrange sits on the A-PILLAR itself (not the door), plus 3x 4"/33W midrange units at the front cowl (between dash and windshield — one each side, one center). Neither of these midrange locations is door-mounted.

Rear doors Unconfirmed

Adapter bracket neededunconfirmed

Factory audio integration

Factory amp / premium audioFactory system is fully digital/amplified, no traditional head unit — shared trait across all EVs in this category
Adding subs without a head-unit swapConfirmed straightforward for the box/mounting; same 16V electrical caveat as Model 3 applies here
Head unitNo replacement needed

Mounting locations

Trunk Solid

IMPORTANT GENERATION CUTOFF, do not extend this entry's data past 2024: Tesla redesigned the Model Y interior for the 2025 'Juniper' refresh, and existing enclosures are explicitly confirmed NOT compatible with 2025+ due to different cargo dimensions — a 2025+ entry needs its own dedicated research pass, this one's data does not carry forward. For 2020-2024: ZEnclosures 10" sealed, 9.00" cutout, 9.00" mounting depth, 1.41 ft3 mono chamber. DIY sub-trunk build: 18.9"x13"x6" (.75" wood), 0.5 ft3 net. Real positive install note found across multiple sources: these enclosures preserve full use of the main trunk space and underneath storage compartments — genuinely low-impact installs for this vehicle.

Before you cut anything

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.
