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. Jeep's own spec sheets (MY2017 and MY2024, identical) give the cargo area: distance between the wheelhouse interior trim 38.1"; cargo width at the liftgate opening 36.9" minimum to 42.1" maximum; maximum cargo height at the liftgate opening 27.2"; liftover height 31.1" (ground to the liftgate scuff trim). Cargo floor length is not published. |
| Known obstructions | The factory sub panel is described as an expensive trim piece requiring careful removal — a 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 (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 (sourceable used-market replacement part) — no aftermarket vehicle-specific molded enclosure was found for the Compass; confirmed genuinely absent |
|---|---|
| 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. 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 | Not an A-pillar tweeter on the 2017 premium system, per Jeep: Jeep's MY2017 BeatsAudio list has no front tweeters — "Two, 3.5-inch speakers in the instrument panel", two 6x9 front door speakers, two 6x9 rear door speakers, "Two one-inch rear door tweeters", an 8-inch DVC subwoofer and a 12-channel amplifier. Jeep has not published whether the later Alpine system (2018+) adds front tweeters (an OEM listing bundles Alpine speakers and tweeters together). |
| Factory speaker size | 6x9" with a 1" tweeter in each rear door on the MY2017 premium (BeatsAudio) system, per Jeep ("Two 6x9-inch rear door speakers", "Two one-inch rear door tweeters"); Jeep does not publish the base six-speaker system's rear size. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Rear doors (Jeep MY2017 premium system: "Two one-inch rear door tweeters"). |
| Factory amp / premium audio | Alpine Premium Audio System (available trims): 9 speakers, a 12-channel 506W amplifier, and a factory 8" subwoofer — 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). Jeep feature-availability sheets: six speakers standard on every trim in both years (2017 and 2025). MY2017: "Beats premium audio system, includes nine speakers with subwoofer and amplifier", optional on Latitude, Trailhawk and Limited (not Sport). MY2025: "Alpine premium audio system with nine speakers, including subwoofer", not available on Sport, packaged on Latitude, Trailhawk and Limited (Sun and Sound Group; included with the High Altitude Package). So the nine-speaker system was Beats-branded at launch and Alpine-branded by 2025; the year the badge changed is unknown. Jeep's MY2017 release confirms the 12-channel amp and 8" DVC subwoofer; the 506W figure is not on Jeep's sheets. |
|---|---|
| Adding subs without a head-unit swap | Confirmed via a 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 |
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. 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. Jeep also sold the first-generation (MK) Compass as a 2017; that car is the 2007-2017 page, so both pages carry 2017.

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.
