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, 2-row and optional 3rd-row jump seats
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | cargo area, general |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found. |
| Known obstructions | P300e PHEV trims: none of significance — see hybrid_ev_note, this is a genuinely safe PHEV unlike several excluded on other vehicles covered here. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" or 1x10" powered, tapping factory wiring (non-Meridian trims) or the under-seat factory sub (Meridian trims) |
|---|---|
| Box type | n/a — powered unit |
| Location | cargo area or under driver's seat |
| Subwoofers | 1x10" or 1x12" sealed, custom-built (no named molded enclosure confirmed) |
|---|---|
| Box type | sealed, custom |
| Location | cargo area — P300e PHEV trims retain the spare-tire well, so this location is NOT restricted to gas trims only, a genuine advantage over several other PHEVs already excluded on other vehicles covered here |
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 | 165mm (6.5") woofer plus a 3" midrange (confirmed on both the base 180W 6-speaker system and detailed further on the 400W Meridian 12-speaker system, which places a midrange speaker within each front door specifically). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Midrange | IN THE DOOR — real, confirmed 3" midrange within each front door, added on the 400W Meridian 12-speaker tier specifically (not present on the base 6-speaker system). |
| Factory speaker size | 165mm (6.5") woofer, base system. Real, specific, slightly conflicting sourcing: one prior-year (2015) source describes a 1" tweeter specifically in the REAR doors (not front) on that model year's layout — flagged as a real, sourced discrepancy from the more commonly cited front-mirror-triangle tweeter placement (25mm, in the mirror triangles per the current 180W system spec), not resolved to one definitive layout across all years. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Midrange | n/a — no rear midrange confirmed |
| Factory amp / premium audio | Real, specific, three-tier Meridian breakdown confirmed via Land Rover's own Meridian-at-a-glance spec sheet: (1) base 6-speaker, 180W system — 165mm door woofers x4, 25mm tweeters in the mirror triangles; (2) Meridian Sound System, 12 speakers, 400W — adds a dashboard center midrange speaker, a midrange speaker in each front door specifically, and a factory SUBWOOFER MOUNTED UNDER THE DRIVER'S SEAT (a real, specific, unusual factory sub placement worth noting — not a trunk sub); (3) Meridian Surround Sound System, 15 speakers, 650W — the top tier, exact additional speaker locations beyond the 12-speaker tier not independently confirmed. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — cargo-area builds don't touch the head unit; the factory under-driver's-seat sub location (Meridian-equipped trims) is a plausible tap point, not independently confirmed as a documented procedure. |
| Head unit | No replacement needed |
Real, dedicated forum community (discoverysport.net) with active subwoofer-install discussion for this exact model, distinct from the broader Land Rover/Range Rover forums. No specific commercial molded enclosure was confirmed, but the factory Meridian system (see audio_integration) is already substantial on upper trims — real prior-year data point (2015 model) confirms 6.5" front/rear door woofers, 3" front-door midrange, and 1" rear-door tweeters as the base non-Meridian layout.

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.
