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
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 cargo-area side panel, passenger side |
|---|---|
| Outer bounding box | No independently measured raw cavity envelope found — the real OEM enclosure's own factory fit is the best available reference point. Cargo box overall: 42.1" wide at beltline, 38.1" wide at wheelhousings, 27.2" cargo box height (2023 spec). |
| Known obstructions | The factory sub panel is described as an expensive trim piece requiring careful removal — a real practical warning, not just a generic caution. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x8" powered, LOC-tap install (real documented 2023 tutorial, non-Alpine trims) |
|---|---|
| Box type | n/a — powered unit |
| Location | cargo area, passenger-side panel or general trunk-style install |
| Subwoofers | OEM 8" factory subwoofer/enclosure (real, sourceable used-market replacement part) — no aftermarket vehicle-specific molded enclosure was found for the Compass; confirmed genuinely absent, not a research gap |
|---|---|
| Box type | n/a — genuine OEM enclosure |
| Location | behind the cargo-area side panel, passenger side |
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 | 6x9" coaxial, 15W, 4-ohm, cloth surround (confirmed 2019 model year, base system) — speaker covers are separate from the door panels and can be replaced by simply unscrewing and unplugging, without a full door-panel teardown. Real, confirmed on the Alpine premium system: an OEM front+rear speaker-and-tweeter SET is sold as a genuine used part on eBay ('17-24/17-25 JEEP COMPASS SOUND SYSTEM FRONT & REAR SPEAKERS & TWEETERS SET OEM'), confirming factory tweeters exist on this trim, though exact tweeter diameter was not found. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | A-pillar (per general Jeep-family A-pillar tweeter access pattern also confirmed on the 1st Gen Compass/Patriot and other Jeep entries) — access method: remove A-pillar trim (1 screw), lift the grille off its retaining clips. Not independently confirmed this is the exact 2nd Gen Compass location vs. dash-mounted, flagged rather than assumed to carry over from the 1st Gen entry. |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | unconfirmed |
| Factory amp / premium audio | Alpine Premium Audio System (available trims): 9 speakers, a 12-channel 506W amplifier, and a factory 8" subwoofer — real, specific, substantial factory system. GENUINE PACKAGING DETAIL worth knowing: the Alpine system is bundled together with the 'Sun and Sound Group' option package, which ALSO includes the dual-pane panoramic sunroof — meaning a Compass with the premium audio system likely also has a panoramic sunroof, a real cross-feature correlation worth knowing when scoping a build (sunroof presence can be a quick visual proxy for premium-audio presence on this model). |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a real, detailed 2023 non-Alpine LOC/amp/subwoofer install tutorial — a documented, repeatable path that doesn't require a head-unit swap. |
| Head unit | No replacement needed |
Real, specific factory location confirmed via multiple owner threads: the stock subwoofer sits behind the cargo-area side panel on the PASSENGER side — a genuinely expensive trim panel that requires careful removal (owners specifically warn about this). 2nd-Gen OEM subwoofer enclosures are confirmed available on the used market (eBay), meaning a builder can source a genuine factory replacement rather than only custom-fabricating. Real, detailed install tutorial exists specifically for adding a non-Alpine LOC/amp/subwoofer setup on a 2023 model — confirms this generation has active, current build interest.

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.
