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 Coupe
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | trunk, driver side (compact) or full-width (large ported) |
|---|---|
| Outer bounding box | No independent trunk WxH found — product depth/volume table used as proxy: single-sub depth scales 14"-20" by driver size (10"-18"), volume 2.75-5 ft3. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2008-2023 Dodge Challenger Sub Box Large Sealed': 25 x 32 x 15 in (as printed; axes not labelled), 4 ft3, trunk, from the floor hinge toward the back seat, leaving room to mount amplifiers; NET Audio '2008-2023 Dodge Challenger Sub Box Medium Sealed': 31 x 12 x 14 in (as printed; axes not labelled), 2 ft3, trunk. 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 08-23 DODGE CHALLENGER': Height 14 1/4", Length 38 3/4", Top Depth 10 1/4", Bottom Depth 16 1/2" (labelled by Ground Shaker), 3.24 FT^3 total; 1.62 FT^3 per subwoofer, FITS BEHIND REAR SEAT; Ground Shaker 'BLACK 15" DUAL SEALED SUB BOX, FITS 08-23 DODGE CHALLENGER': Height 15", Length 38", Top Depth 10 1/2", Bottom Depth 20" (labelled by Ground Shaker), 3.60 FT^3 total; 1.80FT^3 per subwoofer, FITS BEHIND REAR SEAT. |
| Known obstructions | None specifically documented beyond shared LC-platform trunk shape (same family as Charger/300) |
| Usable volume estimate | 3.75 ft³ |

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" — confirmed for both base and Boston Acoustics-equipped systems, 2008-2014. IMPORTANT divergence from the shared-platform Charger/300 pages: the Challenger's top 'Premium Sound Group' packs 18 total Harman Kardon speakers with an 825W Class-D amp — a genuinely bigger/different system than the Charger's 10-speaker HK tier, despite the shared LX/LY/LD platform. Don't assume the two share an identical top-tier system just because the platform and dash-corner tweeter layout are shared. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | Dash corners — same location as the shared-platform Charger/300 pages. Common aftermarket relocation: A-pillar custom tweeter pods, used by owners to improve soundstage beyond the factory dash-corner position. |
| Midrange | Confirmed on the 18-speaker Premium Sound Group tier specifically ('high-efficiency subwoofers, midrange speakers, tweeters' explicitly named as separate components) — not confirmed present on lower tiers. |
| Factory speaker size | not independently confirmed |
|---|---|
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — not confirmed |
| Factory amp / premium audio | Confirmed multi-tier system: base, Boston Acoustics (2008-2014 era), and factory options across Beats/Harman Kardon/Alpine depending on model year — the top 'Premium Sound Group' packs 18 total Harman Kardon speakers with an 825W Class-D amplifier, a genuinely large factory system. Stellantis's own 2015 Challenger press kit gives the tiers as: base "six premium speakers"; Sound Group I "six premium speakers and a 276-watt amplifier"; Sound Group II "nine amplified speakers with subwoofer and a 506-watt amplifier"; R/T Plus "six Alpine speakers with subwoofer and 276-watt digital amplifier"; Premium Sound Group "Harman Kardon GreenEdge technology 900-watt amplifier, 18 premium speakers". CONFLICT: 825 W Class-D above vs 900 W in Stellantis's 2015 kit — the 825 W figure may belong to another model year. Sound Group II and R/T Plus both have a factory subwoofer, which matters when tapping the factory system. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit |
| Head unit | No replacement needed |
Shares the Fox Acoustics '300/Challenger/Charger' cross-model product with the Charger page already — same platform family. Genuinely rich, size-dependent spec table found: single-sub box dimensions scale by driver size — 10"=14" deep/2.75 ft3/tuned 40Hz, 12"=16" deep/3.75 ft3/tuned 35Hz, 15"=20" deep/5 ft3/tuned 30Hz, 18"=20" deep/5 ft3/tuned 30Hz. A larger multi-sub option: 4.7 ft3, 12" mounting depth, fits 3x8"/2x10"/2x12", tuned 34-37Hz. A compact 'Magic Box' (driver-side only) fits a single 10"/12"/13" in 1.0/1.05/1.1 ft3 respectively — a genuinely useful small-footprint option distinct from the full-width builds.

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.
