AP4-FD32: Advanced Amplifier Interface for Select Ford Vehicles

Introduction and Features

The AP4-FD32 offers a 6-channel pre-amp output, enabling the integration of aftermarket audio equipment. It leverages digital A2B audio data and CAN data to deliver a variable 5v RMS pre-amp output. Key capabilities include fading, balance, equalization, and level control. The interface also preserves crucial vehicle audio features like navigation prompts, safety chimes, Bluetooth, and voice activation. Additionally, it provides a data bus controlled remote amplifier turn-on wire and a 2-channel fiber optic digital audio output (TOSLINK).

Key Features and Compatibility

• Provides 6-channel pre-amp output for aftermarket audio systems.
• Retains factory features such as navigation prompts, safety chimes, and Bluetooth audio.
• Includes a data bus controlled remote amplifier turn-on wire.
• Offers a 2-channel fiber optic digital audio output (TOSLINK).
• Compatible with Ford vehicles featuring an A2B data bus controlled premium sound system (look for B&O badges on speakers).
• Requires an aftermarket amplifier to power vehicle speakers, as the factory amplifier is disconnected.

Installation and Configuration

The AP4-FD32 installs at the factory amplifier location. A T-harness is included to access factory speaker wiring behind the radio. Proper installation involves connecting the provided harnesses, setting DIP switches for desired features (e.g., two-channel mode, output voltage), and connecting the aftermarket amplifier's signal cables and remote turn-on. The document details manual and software-based methods for setting minimum volume and chime levels, as well as firmware updates and troubleshooting.
