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: 2-Door, 4-Door (Unlimited)
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | multiple named locations — rear cargo area, under rear seat, under front seat, wheel-well behind passenger seat |
|---|---|
| Outer bounding box | Rear cargo (largest, ported builds up to 12"): ~21.5"W x 14"H x 16"D starting point per forum builder. Under-seat: ~0.5 ft3. Wheel-well behind passenger seat: 0.59-0.72 ft3 depending on 6" depth option. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2007-2018 Jeep Wrangler JKU Unlimited Cargo Tub Sub Box': 39 x 30 x 7 in (as printed; axes not labelled), 0.6 ft3, in the factory cargo tub behind the seat (replaces cargo bin); NET Audio '2007-2018 Jeep Wrangler JKU Unlimited Shallow Downfire Sub Box Sealed': 45 x 23 x 8 in (as printed; axes not labelled), 1.76 ft3, behind rear seat, back of back seat to where the cargo floor lifts. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: Ground Shaker 'BLACK 10" DUAL SEALED SUB BOX, FITS 07-22 JEEP WRANGLER 4-DOOR': Height 13 1/4", Length 49", Top Depth 11", Bottom Depth 12 1/4" (labelled by Ground Shaker), 1.97 FT^3 total; 0.98 FT^3 per subwoofer, FITS BEHIND REAR ROW SEAT. |
| Known obstructions | Rollbar constrains rear cargo shape; wheel-well intrusion shapes that location's usable volume directly. |
| Usable volume estimate | 0.6 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" small sealed |
|---|---|
| Box type | sealed |
| Location | under seat or wheel-well mount, ~0.5-0.7 ft3 |
| Subwoofers | 2x10" or 2x12" sealed (named option: Skar Audio behind-2nd-row enclosure, no modification needed) or 1x12" swing-gate weatherproof (named option: Stinger, mounts on the tailgate/spare-tire-carrier area) |
|---|---|
| Box type | sealed, vehicle-specific |
| Location | behind 2nd row (Skar) or swing-gate/tailgate mount (Stinger) |
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 | 6.5" component (separate tweeter) — confirmed via retailer sourcing. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Dash-mounted, not A-pillar — confirmed detail: factory used two different styles of dash tweeters depending on standard vs. premium (Infinity/Alpine) system trim. |
| Factory speaker size | 6.5" (same as front, Unlimited 4-door only) |
|---|---|
| Known obstructions | 2-door body style has no rear doors |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — this generation's tweeter is dash-mounted, not doubled to the rear |
| Factory amp / premium audio | Alpine-branded factory/dealer-option premium audio existed on some trims across these years — exact per-trim/year spec not confirmed. |
|---|---|
| Adding subs without a head-unit swap | Likely straightforward given the era's simpler electronics vs. modern trucks, not independently confirmed. |
| Head unit | No replacement needed |
Much smaller and more varied than a full-size SUV — builder data points: rear cargo area can fit a 12" in a large ported enclosure; under-seat custom builds run around 0.5 ft3; one builder used 21.5"w x 14"h x 16"d as a starting box; wheel-well-mounted box behind passenger seat ran 0.59-0.72 ft3 depending on depth (6" deep option). This is a vehicle where location choice matters as much as vehicle model — multiple named sub-locations with different volumes apply here more than on most vehicles.
Outside links. Some are commercial products, some are owner builds posted on forums — the label says which. We do not endorse any of them.

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.
