Advanced Amplifier Integration for 2025+ Ford B&O Systems

The PAC AP4-FD32 (AmpPRO Series) is a specialized amplifier integration interface designed for select 2025 and newer Ford vehicles equipped with the premium B&O (Bang & Olufsen) A2B data-bus sound system. This module allows you to bypass the factory amplifier and output a clean, flat, high-voltage signal to aftermarket amplifiers without losing critical vehicle functions. By tapping into the digital A2B stream, it eliminates factory bass roll-off and processing, providing a high-fidelity foundation for custom audio builds.

The AP4-FD32 delivers a 6-channel 5V RMS preamp output (Front, Rear, and Sub) that is fully adjustable and switchable to 4V if needed. It includes a vehicle-specific T-harness for a plug-and-play installation, retaining all factory audio features such as navigation prompts, SYNC, Bluetooth, and safety chimes. Additionally, it features a TOSLINK optical output for direct connection to high-end Digital Signal Processors (DSPs) and a remote turn-on lead for your aftermarket gear.

Product Features:

  • Compatible with select 2025-2026 vehicles from Ford
  • Compatible on models with B&O A2B factory amplified systems
  • Factory amplifier must be removed from the vehicle when installing this interface
  • Provides a 6 channel pre-amp output for use with aftermarket audio equipment
  • Provides 2 channel fiber optic digital audio output (TOSLINK)
  • Retains factory navigation prompts, safety chimes, Bluetooth, and voice activation
  • Delivers variable 5V RMS pre-amp output with fading, balance, equalization, and level control
  • Plug and play connection, no cutting or splicing required
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Note: Not compatible with 2025+ Explorer and Expedition.
