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 |
| Known obstructions | None specifically documented beyond shared LC-platform trunk shape (same family as Charger/300) |
| Usable volume estimate | 3.75 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" compact 'Magic Box', 1.0 ft3 |
|---|---|
| Box type | sealed |
| Location | trunk, driver side, minimal space used |
| Subwoofers | 2x12" ported, 4.7 ft3, tuned 34-37Hz |
|---|---|
| Box type | ported |
| Location | trunk, full-width |
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. Real, IMPORTANT divergence from the shared-platform Charger/300 entries: 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 entries. Real, common aftermarket relocation: A-pillar custom tweeter pods, used by owners to improve soundstage beyond the factory dash-corner position. |
| Midrange | Real, 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 | Real, 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. |
|---|---|
| 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 entry 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.
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.
