Full 2014 Dodge Charger Speaker Wiring Diagram with Color Codes Guide

Install aftermarket amplifiers or subwoofers without guessing–use the factory color-coded harness segments directly behind the dashboard trim panel on the driver side. Locate the 24-pin main plug labeled C1: pins 6 (dark green) and 15 (light blue/brown stripe) deliver front door tweeter outputs, while pins 3 (gray/black stripe) and 18 (violet/green stripe) handle rear full-range signals. Strip insulation carefully to prevent shorting copper strands against adjacent terminals.

Verify ground paths before powering on; chassis points beneath the front seats (black bolt heads marked M6) must show continuity under 0.2 ohms resistance. If swapping to component crossovers, bypass the 3.5 mm coupling capacitor on the brown/pink wire at pin 19–factory roll-off frequencies start at 3 kHz. Keep RCA interconnects shielded; wrap each harness bundle with spiral braid to suppress engine noise intrusion.

For cabin-wide fidelity, pair each 2-ohm voice coil with dedicated amplifier channels. Match power ratings: OEM head unit pushes 15W RMS; aftermarket units typically require 4-gauge copper fuse links at the battery. Confirm polarity before sealing connections–miswiring tweeters will invert phase, collapsing midrange imaging.

Upgrade tweeters only after validating mid-bass response. Remove the A-pillar trim to expose door speaker harnesses; orange/white and tan/yellow wires correspond to negative and positive terminals. Swap factory 1-inch silk domes for 25 mm neodymium tweeters rated to 20 kHz–mounting depth clearance is 1.7 inches maximum. Seal edges with closed-cell foam to prevent rattles.

Audio System Pinout for the 2014 Model SXT Sedan

Locate the factory harness behind the dashboard panel on the driver’s side–specifically the 12-pin black connector labeled C1. Pins 1 and 2 deliver the front left channel; pin 1 carries the positive feed (solid color wire) while pin 2 is the negative return (striped). Rear left audio follows a similar pattern at pins 7 and 8. Front right occupies pins 3 and 4; rear right maps to pins 9 and 10. Amplifier trigger wires (if applicable) appear at pins 5 (12 V remote) and 6 (ground reference). Use a 16-18 AWG crimp terminal when splicing to preserve signal integrity through 4 Ω loads typical of OEM drivers.

Aftermarket adapters like Metra 70-5802 or Scosche CR06B often simplify wiring, but verify their pin assignment against the aftermarket head unit’s harness–especially if the radio expects balanced signals. For direct splicing, strip ¼ inch of insulation, twist tightly, and solder joints with 60/40 rosin-core solder; avoid electrical tape–heat-shrink tubing forms a moisture-resistant seal. If retaining the stock amplifier (Uconnect 4), maintain the data bus connection via pins 11 and 12 on connector C2 (teal/red and teal/orange wires) to prevent flickering display errors.

Ground connections should be bolted directly to the chassis behind the kick panel near the firewall grommet–avoid paint or rust. Test continuity with a multimeter before finalizing: set to 200 Ω, probe between each positive speaker wire and chassis ground; reading should exceed 3 Ω for proper return path. For tweeters, confirm the factory attenuation network isn’t bypassed–if rear door woofers exhibit phase cancellation at 250 Hz, trace the inline 1000 µF capacitor found in the original door loom and reinstall it in series with the new coaxial setup.

Color Codes for Aftermarket Sound System Connections

Locate the factory harness behind the head unit to match each audio channel to its corresponding cable. Standard configurations use these primary colors for most trim levels:

• Front Left Positive: Dark green with orange tracer
• Front Left Negative: Dark green with black tracer
• Front Right Positive: Gray with light blue tracer
• Front Right Negative: Gray with violet tracer
• Rear Left Positive: White with pink tracer
• Rear Left Negative: White with brown tracer
• Rear Right Positive: Purple with yellow tracer
• Rear Right Negative: Purple with dark blue tracer

For vehicles equipped with amplified setups, check for additional wires behind the rear deck. These typically follow a slightly different scheme:

• Subwoofer Positive: Light green with white tracer
• Subwoofer Negative: Light green with dark green tracer
• Remote Turn-On: Bright blue with white tracer

Verify connections with a multimeter before finalizing splices. Factory cables may include extra strands for features like speed-sensitive volume or navigation voice guidance. Disconnect the battery’s negative terminal to prevent short circuits while handling these components.

Certain luxury packages substitute gold connectors for standard copper. These require crimping tools rated for high-conductivity alloys to maintain signal integrity. Avoid twisting exposed wires – use solder or butt connectors for a secure, long-term installation.

If color markings differ from the above, consult the door jamb sticker for the audio system’s part number. Cross-reference this code with manufacturer documentation, as mid-cycle updates occasionally alter wiring conventions without notice.

For premium setups with fiber optics, the data line appears translucent amber. Do not attempt to splice this strand – replace the entire harness if damaged. Use factory-matched connectors to prevent signal degradation.

Aftermarket amplifiers demand heavier gauge power cables than stock systems. Route these along existing pathways near the vehicle’s frame rails, securing them every 18 inches with nylon ties. Keep power runs separated from RCA lines by a minimum of 6 inches to prevent interference.

Step-by-Step Guide to Finding Door Audio Component Junctions

Begin by removing the interior door panel trim using a plastic pry tool to avoid damaging clips. Work along the perimeter, starting near the handle assembly where fasteners are often hidden beneath a small cover. Check behind the manual window crank (if equipped) or the power switch cluster–these areas typically conceal the first set of retaining screws. For vehicles with pull-style latches, locate the two screws under the bottom edge lip, then release the upper tabs by pulling outward with steady pressure.

• Driver-side front: 8 plastic clips, 3x 8mm screws (2 near handle, 1 behind map pocket)
• Passenger-side front: 6 clips, 2x 7mm screws (both under armrest)
• Rear doors: 5 clips per side, no concealed screws; lift upward after removing lower sill trim

Disconnect the electrical harness from the window regulator and side mirror actuator before attempting to lift the panel fully. The audio signal connectors sit behind a foam-backed isolation pad–peel this back carefully to reveal the pair of 2-pin Molex plugs. Label each plug with masking tape to prevent mismatching during reassembly. If corrosion is present, apply dielectric grease to terminals to improve conductivity.

If the connectors are absent or wires appear cut, trace the harness bundle through the rubber grommet between door and chassis. Strip any damaged sections using 16-gauge crimp connectors, ensuring polarity matches the factory color code: solid brown = positive, brown with tracer = negative. Test continuity with a multimeter before securing the panel back into place.

Reinstallation requires reverse steps–align all clips before pressing firmly, then torque screws to 12 in-lbs. Verify operation by cycling the stereo system and listening for balanced output across all channels. If distortion persists, recheck ground connections near the hinge pillar or beneath the seat rails.

Amplifier Connection Pin Configuration for Custom Audio Upgrades

Begin by linking the aftermarket power amplifier’s remote turn-on terminal to the head unit’s dedicated control wire–typically a 12V blue or blue/white conductor in the OEM harness. Verify the pin assignment in the factory connector layout to avoid mistakenly tapping into constant power sources, which can drain the battery.

Locate the front and rear signal outputs from the vehicle’s audio controller. The front left and right channels often occupy pins 1 and 2, while rear channels may use pins 3 and 4. Cross-reference these positions with a multimeter set to AC voltage mode to confirm signal presence during audio playback before splicing into the amplifier inputs.

Use twisted-pair, shielded RCA cables for signal transmission between the head unit and amplifier to minimize electromagnetic interference. If the factory system lacks preamp outputs, install a line-level converter directly on the high-level speaker wires–matching the impedance of the amplifier (typically 10kΩ) to prevent signal degradation or distortion.

For subwoofer integration, identify the low-pass filtered output from the audio processor or tap into the rear speaker leads using a dedicated mono channel on the amplifier. Configure the amplifier’s low-pass filter frequency between 80-120Hz to ensure seamless crossover with midrange drivers, avoiding dual filtration that can create phase cancellation.

Ground the amplifier’s chassis to a bare metal point on the vehicle’s frame, at least 18 inches from the battery negative terminal to reduce ground loop hum. Avoid painted or coated surfaces; clean the connection point with a wire brush and secure the ground cable with a star washer to maintain conductivity under vibration.

The main power feed should route directly from the battery’s positive post through a 4-6 AWG cable, fused within 18 inches of the post using an ANL or mini fuse holder. Bypass the factory fuse box to prevent voltage drop across connection points, which can starve the amplifier of power during peak demand, causing clipping or shutdown.

Advanced Signal Processing Configuration

If the amplifier includes built-in digital signal processing (DSP), program the input gain to match the head unit’s output voltage–typically 2-4V for modern systems. Use an oscilloscope or a test tone generator to set the gain structure precisely, preventing overdrive that can introduce harmonic distortion. Calibrate the crossover slopes (12dB/octave for most applications) and equalizer settings to complement the vehicle’s acoustics, accounting for cabin resonances around 200-400Hz.

For vehicles with active noise cancellation or factory equalization, disable or bypass these features before connecting the amplifier. Some OEM systems modulate the signal in real-time, which can conflict with aftermarket tuning. If bypass isn’t possible, use a DSP with phase correction to align the signals, ensuring coherent soundstage reproduction without comb filtering effects.
