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 SUV, 3-row
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | under cargo floor, spare tire area |
|---|---|
| Outer bounding box | Not independently measured — confirmed real-world fit for amp, sub, and wiring under the cargo floor |
| Known obstructions | 450e plug-in hybrid trim has a modest cargo reduction (31.5 ft3 vs. 33.3 ft3 standard) — verify trim before assuming full-size availability |
| Usable volume estimate | 1 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" sealed, under cargo floor |
|---|---|
| Box type | sealed |
| Location | under cargo floor, spare tire area — zero visible impact |
| Subwoofers | full aftermarket system replacement (real example: Helix + Focal on an AMG GLE63S) |
|---|---|
| Box type | sealed |
| Location | under cargo floor or integrated full-system replacement |
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 | unconfirmed — Crutchfield fit-database coverage confirmed to exist but specific dimensions not surfaced. The 13-speaker, 590W Burmester surround system (5 midrange + 4 tweeters + 2 front bass woofers + 2 surround-effect speakers per forum sourcing; Mercedes's 2024 GLE article confirms 13 speakers, a 9-channel amplifier and 590 W) is what Mercedes's 2024 article calls "the premium audio system"; whether it is standard or optional on a given trim is not stated on the pages read (forum sourcing calls it the base system, and calling it "an option" goes further than Mercedes's wording) — matches the same speaker-role breakdown pattern confirmed on the sister C-Class/E-Class pages, but exact per-door dimensions not found for this SUV specifically. |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | Not independently confirmed by exact door/A-pillar mount point. Confirmed detail on the Burmester 3D tier: a CENTER-DASH tweeter is added above the infotainment screen, matching the same real feature found on the sister C-Class/E-Class pages. our other confirmed Mercedes-Benz Burmester systems (C-Class, E-Class) place their base-tier tweeter in the A-PILLAR — plausible the GLE follows the same convention, but not independently confirmed for this vehicle. |
| Midrange | Confirmed 5 midrange drivers exist across the 13-speaker system (matching the sister C-Class/E-Class's 4" door-mounted midrange pattern), but exact per-location dimension/placement not independently confirmed for this generation. |
| Factory speaker size | unconfirmed |
|---|---|
| Adapter bracket needed | unconfirmed |
| Factory amp / premium audio | Burmester available on equipped trims, same family as the C-Class/E-Class. Mercedes-Benz USA's 2024 GLE article gives the Burmester surround system as 13 speakers, a 9-channel DSP amplifier and 590 W. Mercedes's 2024 article calls it "the premium audio system" without saying standard or optional (read directly 2026-10-02: "The premium audio system is the Burmester® surround sound system"); its 2020 quick reference guide lists the larger Burmester High-End 3D Surround Sound System as optional (no counts). Whether the 13-speaker Burmester is standard on some 2024 trims is not settled by the pages read, and the base system is not described on them. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward via the under-floor location |
| Head unit | No replacement needed |
Real cargo space: 33.3 ft3 standard (31.5 ft3 on the 450e plug-in hybrid trim — a real, if modest, hybrid-trim reduction worth noting, smaller than the RAV4 Prime case but the same category of finding), up to 74.9 ft3 folded. Confirmed build location: all electronics (amp, sub, wiring) can fit UNDER the cargo floor where the spare tire is located — same general pattern as other spare-area builds found across this guide (Rogue, Forester, X5).

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.
