At a Glance

• Front, rear, and subwoofer preamp outputs rated up to 5 volts RMS
• Retains supported factory volume, fade, balance, tone controls, chimes, prompts, and communication audio
• Includes a wired subwoofer-level control for convenient level adjustment
• Optional TOSLINK output is available with the separately sold PAC APA-TOS1.
• Aftermarket amplifier, amplifier power wiring, signal cables, speakers, and application accessories are sold separately

Exact Vehicle Compatibility

Find your vehicle below and match the year, model, factory audio system, screen, connector, and equipment details in the same row. Applications are derived from PAC’s June 2026 interface matrix and validated against the current dealer product record. If the details do not match, contact MCOR before ordering.

Compatibility & Installation Requirements

• Factory system: supported amplified or specifically listed non-amplified Chrysler, Dodge, Jeep, Ram or Maserati audio system.
• Factory amplifier: Factory-amplifier handling depends on the application. In non-amplified vehicles, an aftermarket amplifier must power the cabin speakers after the radio is reconfigured.
• Amplifier connections: Use the application-specific PAC speaker harness and load resistors listed in the table when required.
• Programming: Install the current PAC firmware and follow the current application guide before final system configuration.
• Screen size, body style and factory-amplifier requirements must match the exact application.
• Non-amplified vehicles with active noise cancellation require the ANC module to be bypassed.
• Professional installation and system tuning are strongly recommended.
