• Expansion / speaker wiring interface harness for newer Chrysler, Dodge, Jeep, and RAM vehicles
• Designed for use with the PAC AP4-CH41 R.2 AmpPRO module (required)
• Adds clean, OEM-style connection to factory amplified or non-amplified systems without cutting factory wiring
Compatibility:
• Select 2021 and newer Chrysler / Dodge / RAM / Jeep vehicles equipped with UConnect5 (factory amplified or non-amplified systems)
• Must be used in conjunction with AP4-CH41 R.2 interface module
Main Features / Capabilities:
• Plug-and-play harness that attaches to the factory amplifier connector (factory combo connector that combines speaker outputs)
• Provides access to all OEM speaker outputs for aftermarket amplification
• Maintains OEM audio features: uConnect, Bluetooth, navigation prompts, warning chimes
• Preserves factory wiring integrity—reversible installation
• Simplifies integration of aftermarket amps or DSPs
Signal / Output Details:
• Outputs are full-range, fixed (5 V RMS) preamp-level signals from factory speaker outputs
• Channels include front, rear, and sub outputs (depending on system)
• Levels of sub channels adjustable with supplied level knob
• Includes remote turn-on output for aftermarket amplifiers
Installation / Notes:
• Connects to the factory amplifier plug—no cutting or modifying factory harnesses
• Hardwire connections required from APH-CH42 to the aftermarket amplifier (speaker outputs)
• The factory amplifier must remain connected when used in factory-amplified systems
• For systems lacking a factory amp, the AP4/APH combination reconfigures the radio output, so an aftermarket amplifier is required to drive speakers
• If the vehicle has Active Noise Cancellation (ANC), bypass or deactivation may be necessary (depending on model)
• Verify pinouts and channels using a tone generator or test signal
Package Includes:
• APH-CH42 wiring harness
