The ZEN-A2B amplifier replacment interface seamlessly converts 2018+ Ford factory A²B® (Automotive Audio Bus) to 12-channel analog RCA and TOSLink output. Adding aftermarket amplifiers to the OE B&O or Revel amplified SYNC3 system has never been so simple. This module integrates directly with the OEM A²B® & CAN bus to retain volume control, full fade (analog only) and balance, treble, mid-range, bass control & will do Bluetooth voice calls with no external speaker (true OEM integration).
