Today's modern vehicle audio systems are becoming increasingly more sophisticated and complex. PAC (R) Audio engineered the AmpPRO 4 Interface for select Ford (R) 2018 and up vehicles to dramatically simplify the installation of upgraded amplifiers in databus-controlled amplified sound systems. AmpPRO allows you to keep the original radio's fit, finish, and features while giving you the freedom to improve the audio performance in record time! The module also retains all audio from other vehicle features such as factory Bluetooth (R) and all warning chimes. A sub level controller and optical output are included.
