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 Sedan
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, through existing opening (no metal cutting) |
|---|---|
| Outer bounding box | No independent trunk WxH found — shared LX/LD platform product proxy: 4.25 ft3 undivided, 11.15" hole size. Vehicle-specific enclosure catalogues; published box footprints are lower bounds on the cavity, not the cavity: NET Audio '2006-2023 Dodge Charger Sub Box Large Sealed': 25 x 32 x 15 in (as printed; axes not labelled), 4 ft3, trunk, from the floor hinge to the back seat; NET Audio '2006-2023 Dodge Charger 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 06-26 DODGE CHARGER': 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 06-26 DODGE CHARGER': 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 | Explicitly flagged by the seller as 'a tight squeeze for the trunk opening' — real installability caveat, not just a volume number |
| Usable volume estimate | 4.25 ft³ |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x10" sealed |
|---|---|
| Box type | sealed |
| Location | trunk |
| Subwoofers | 2x12" ported, 4.25 ft3, tuned 35Hz (real example: Fox Acoustics/Gately shared design) |
|---|---|
| Box type | ported |
| Location | trunk, through existing opening — confirm tight fit before assuming easy install |
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 4-tier factory system: base 6-speaker, Alpine 6-speaker, and 10-speaker Beats OR Harman Kardon (same speaker count, different branding/tuning). |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | Named commercial speaker-pod product confirmed specifically for this generation: CustomSpeakerPods.com '2011-2023 Dodge Charger Speaker Pods | Front, Rear & A-Pillar'. |
| Tweeter | Dash corners on all trims; the 10-speaker Beats/Harman Kardon tiers add a SECOND 3.5" unit in the center of the dash — matches the near-identical pattern already confirmed on our shared-platform Chrysler 300 page (dash/center speaker architecture recurring across the LX/LY/LD platform family). |
| Midrange | n/a — the dash-corner/center units function as combined tweeter/midrange in this system, not a separate 3rd driver |
| Factory speaker size | 6x9" — upper-level systems only |
|---|---|
| Known obstructions | Base systems may not have rear door speakers — verify trim first |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — not confirmed as a rear-door component |
| Factory amp / premium audio | Four tiers: base 6-speaker, Alpine 6-speaker, Beats (10-speaker per other sourcing — no Stellantis page read states its count, so unverified), and Harman Kardon — Stellantis's own 2015 Charger press kit gives the Harman Kardon system as "18-speakers, a trunk-mounted subwoofer and a 900-watt amplifier", and "19 Green Edge speakers" on the SRT (the two counts differ on the same page). 2015 figures only — 2011-2014 and 2016-2023 not read. The trunk-mounted factory subwoofer on Harman Kardon cars matters for any sub install. Honest owner consensus: even the premium Alpine/HK/Beats tiers are described by enthusiasts as using 'poor quality speakers and underpowered amplifiers' relative to what a true component upgrade delivers — don't oversell the factory premium tiers as already great. |
|---|---|
| Adding subs without a head-unit swap | Confirmed straightforward — trunk-based builds don't touch the head unit at all |
| Head unit | No replacement needed |
IMPORTANT CROSS-MODEL PLATFORM-SHARING FOUND: Fox Acoustics sells a dual-12" vented box explicitly for '2005-UP 300 / Challenger / Charger' as ONE product — Charger, Challenger, and Chrysler 300 share the same trunk geometry on the shared LX/LY/LD platform family. Gately Audio's dual-12" trunk enclosure is similarly sold across all three. Spec: 4.25 ft3 undivided, tuned 35Hz, 11.15" hole size — but explicitly noted as 'a tight squeeze for the trunk opening,' a real installation caveat. Enclosures are designed to install through the existing trunk opening with no metal cutting required.
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.
