PAC APH-CH01 Speaker Connection Harness Instruction Manual

1. Introduction

The PAC APH-CH01 is an 18-inch speaker connection harness designed to simplify the integration of aftermarket audio components into select Chrysler and Dodge vehicles equipped with factory amplified sound systems. This harness provides a direct connection to the vehicle's existing speaker wiring, eliminating the need for cutting or splicing factory wires. It is intended for use in custom audio installations where the factory amplifier is being bypassed or replaced, allowing for a clean and reversible installation.

2. Safety Information

• Always disconnect the vehicle's negative battery terminal before beginning any electrical installation to prevent short circuits and damage.
• Ensure all connections are secure and properly insulated to prevent electrical shorts.
• Consult your vehicle's service manual for specific wiring diagrams and component locations.
• If you are unsure about any step of the installation process, seek assistance from a qualified professional installer.
• Do not modify the harness. Any modifications may void the warranty and could lead to improper function or damage.

4. Installation Guide

This harness is designed to connect to the factory speaker wiring at the location of the factory amplifier. The specific location of the factory amplifier varies by vehicle model and year. Refer to your vehicle's service manual for precise amplifier location and removal instructions.

4.1 Preparation

1. Park the vehicle on a level surface and engage the parking brake.
2. Disconnect the negative battery terminal to prevent electrical hazards.
3. Locate and access the factory amplifier. This may require removing trim panels or seats.
4. Carefully disconnect the factory wiring harnesses from the amplifier.

4.2 Harness Connection

The APH-CH01 harness features multiple connectors. Identify the connectors that match the factory speaker output harnesses previously disconnected from the amplifier. The harness is typically used in two main scenarios:

• Bypassing the Factory Amplifier: If you are removing the factory amplifier and installing an aftermarket amplifier, the APH-CH01 connects to the vehicle's speaker wiring. The loose wires on the harness will then connect to the speaker outputs of your aftermarket amplifier.
• Integrating with Aftermarket Line Output Converters (LOCs): If you are retaining the factory head unit and adding an aftermarket amplifier via an LOC, the APH-CH01 can provide a clean signal source from the factory speaker wires to the LOC.

Connect the appropriate end of the APH-CH01 harness to the vehicle's factory speaker wiring connectors. Ensure a firm and secure connection.

4.3 Wiring Identification (General Guidelines)

While specific wire colors can vary, the APH-CH01 typically follows standard aftermarket wiring color codes for speaker connections. It is highly recommended to verify continuity with a multimeter or tone generator before making final connections, especially if your vehicle's factory wiring colors do not match standard conventions.

Connect the corresponding wires from the APH-CH01 harness to your aftermarket amplifier's speaker outputs or line output converter inputs. Ensure correct polarity (positive to positive, negative to negative) for optimal sound quality.

4.4 Final Steps

1. Secure all wiring to prevent rattles or damage from moving parts.
2. Reinstall any removed trim panels or components.
3. Reconnect the vehicle's negative battery terminal.
4. Test the audio system to ensure all speakers are functioning correctly and with proper balance.

5. Troubleshooting

• No Sound from Speakers:
  • Verify all connections to the APH-CH01 harness and aftermarket components are secure.
  • Check the aftermarket amplifier's power, ground, and remote turn-on connections.
  • Ensure the aftermarket amplifier is powered on and not in protect mode.
  • Confirm correct speaker wire polarity.
• Distorted Sound:
  • Check for incorrect wiring polarity.
  • Ensure amplifier gain settings are not too high, causing clipping.
  • Verify speaker impedance compatibility with the amplifier.
• Only Some Speakers Working:
  • Inspect individual speaker wire connections for continuity and shorts.
  • Check the balance and fader settings on your head unit.

If troubleshooting steps do not resolve the issue, contact PAC technical support or a professional installer.
