The Ultimate 2015-2023 Dodge Charger Subwoofer Enclosure & Bass Package Buyer’s Guide

The NVX custom subwoofer platform for the 2015 to 2023 Dodge Charger (7th Generation / LD Body Code) is an aftermarket bass upgrade engineered specifically for modern Charger muscle sedans.

NVX’s bass platform is meant to remedy the Charger’s sound system which struggle to produce physical, low-frequency sub-bass impact.

This is why NVX offers three tailored bass upgrade options for 7th-gen Charger owners:

• a standalone empty enclosure (UBE-DOD-CHA-G7)
• a standalone loaded enclosure (BE-DODCHAG7)
• or a complete plug-and-play amplified bass package (PBK-DODCHA-G7).

Where Is the NVX Subwoofer Enclosure Installed in Your Dodge Charger?

The NVX custom subwoofer enclosure installs directly inside the passenger-side rear trunk corner storage recess behind the wheel arch of the Dodge Charger.

The custom cabinet features a hand-laid fiberglass rear shell that traces the inner sheet-metal contours of the Charger's trunk wall. It slides flush into the passenger-side trunk cavity, directing sound pressure waves inward across the cargo area.

Positioning the enclosure in the passenger-side corner well provides three major functional advantages:

1. Zero Primary Trunk Floor Loss: Your main trunk floorboard, 60/40 folding rear seat pass-through, and tie-down points remain 100% open and usable for luggage, groceries, or gear.
2. Full Spare Tire Access: The enclosure sits entirely inside the side pocket above the floor seam, allowing you to lift the lower trunk carpet mat to reach your spare tire or tire mobility kit without unbolting or moving the subwoofer enclosure.
3. Acoustic Corner Loading: Mounting a woofer directly inside a rigid trunk corner boundary forces sound waves to reflect off metal body panels. This boundary-loading effect acts like an acoustic horn, boosting sub-bass output volume and cabin pressure without drawing extra power from your amplifier.

Important Fitment Note: This custom enclosure platform is engineered strictly for 2015–2023 Dodge Charger models (including SXT, GT, R/T, Scat Pack, and Hellcat trims). It drops directly into the passenger-side trunk pocket without cutting, drilling, or custom panel fabrication. It will NOT fit 2006–2010 (5th Gen) or 2011–2014 (6th Gen) Charger models, nor will it fit Dodge Challenger coupes due to different trunk quarter panel contours.

Why NVX Outperforms Other Brands in Value & Engineering

Upgrading vehicle-specific car bass usually forces buyers to choose between generic square boxes that slide around the trunk, or expensive custom fiberglass boxes that can be quite expensive to build. NVX bridges this gap by offering handcrafted, custom-molded enclosures directly to drivers at an accessible price point.

• Hand-Laid Fiberglass vs. Thin Molded Plastic: Competitor trunk pocket enclosures frequently rely on cheap, thin plastic shells that flex, vibrate, and rattle under heavy acoustic pressure. NVX BOOST enclosures combine a dense multi-layer hand-laid fiberglass rear shell with a rigid 3/4-inch medium-density fiberboard (MDF) front baffle, creating an acoustically dead cabinet that eliminates panel flex.
• OEM-Matched Interior Aesthetics: Covered in plush automotive carpet color-matched to Dodge’s factory trunk lining, the enclosure blends seamlessly into the Charger's interior for an integrated look.
• Direct Value Engineering: Car audio brands tend to charge heavy markup fees while using copper-clad aluminum (CCA) wire or low-excursion woofers. NVX focuses engineering budgets on raw component quality to deliver premium acoustic performance per dollar. These include carbon fiber-reinforced woofer cones, high-temperature voice coils, and 100% oxygen-free copper (OFC) power grids.

Configuration Comparison: Empty vs. Loaded vs. Complete Package

Choosing the right SKU for your Dodge Charger depends on what you need and what you want your system to sound like:

1. Standalone Empty Enclosure (UBE Series)

The UBE-DOD-CHA-G7 includes the custom fiberglass 10-inch sealed box with ~0.52 cu. ft. of internal air volume, pre-wired terminal cup, and internal speaker leads. It can accommodate a 10-inch subwoofer with up to 5.5 inches of mounting depth and a 9.15-inch cutout diameter. Ideal if you already own a 10-inch subwoofer, monoblock amp, and wiring kit.

2. Standalone Loaded Enclosure (BE Series)

The BE-DODCHAG7 includes the custom fiberglass box pre-loaded with an NVX 10-inch shallow-mount subwoofer pre-wired internally to a 2-ohm final mono load. Featuring a durable composite cone, high-roll surround, and high-temperature voice coil, it handles 350W to 500W RMS. Ideal if you already own a 2-ohm stable monoblock amplifier.

3. Complete Bass Package (PBK Series)

The PBK-DODCHA-G7 is the ultimate all-in-one upgrade. It eliminates component guesswork by uniting factory-matched equipment engineered to operate in total acoustic harmony. It includes:

• The pre-loaded BE-DODCHAG7 10-inch BOOST enclosure
• An NVX VADM1v2 Micro Class-D Monoblock Amplifier (400W RMS @ 2 ohms / 600W RMS @ 1 ohm)
• An NVX XLCA2X Active Line-Output Converter with xBOOST signal restoration
• A wired remote dash-mounted bass level control knob
• An NVX XKIT82 100% Pure Oxygen-Free Copper (OFC) 8-Gauge Wiring Kit

Why a Sealed Enclosure Is Ideal for the Charger’s Acoustics

Sedan cabins create an enclosed acoustic space where sound pressure waves travel from the trunk compartment into the seating area. In this environment, ported (vented) boxes can frequently generate loose, boomy bass overhang that masks mid-range vocals and instrumentals.

A sealed enclosure acts as a pneumatic air spring behind the woofer cone. As the voice coil travels, internal air pressure keeps the moving cone under strict mechanical control, preventing over-excursion and yielding fast, articulate transient response.

Inside a Dodge Charger, a sealed 10-inch enclosure produces tight, punchy kick drums and articulate basslines that hit hard without muddying your soundstage—delivering clean, controlled bass across rock, hip-hop, electronic, and high-volume driving.

Power Integration, Factory Radio & System Safety

Overcoming Dodge Uconnect Factory Bass Roll-Off

Factory Dodge Uconnect infotainment head units incorporate internal equalizer algorithms that automatically reduce low-frequency bass output as you raise the main volume knob. This factory roll-off protects weak stock door speakers, but it leaves aftermarket subwoofers lacking low-end output at higher volumes.

Included in the complete bass package (PBK Series) is the NVX XLCA2X Active Line-Output Converter. It taps into factory speaker lines behind the radio or at the factory amplifier harness in the trunk, converts high-level speaker signals into clean low-level RCA outputs, and uses integrated xBOOST signal restoration (30 Hz–60 Hz) to feed a flat, distortion-free sub-bass signal to your monoblock amp.

Recommended Monoblock Amplification: NVX VADM1v2

The complete bass package pairs the enclosure with the NVX VADM1v2 Micro Class-D Monoblock Amplifier. Delivering clean power at 2 ohms, its ultra-compact chassis easily mounts out of sight underneath a front seat or behind trunk side trim panels. Its conformal-coated circuit board protects internal electronics against moisture and seasonal temperature swings.

100% Pure OFC 8-Gauge Power Grid

Sustaining continuous high-wattage RMS loads requires clean electrical delivery. The package includes an NVX XKIT82 8-Gauge Oxygen-Free Copper (OFC) Wiring Kit. Pure copper conductors ensure maximum current transfer from the battery to the amplifier without creating high resistance or dangerous wire heat.
