PAC Audio AmpPRO 4 Advanced Amplifier Interface - AP4-TY12

Today's modern vehicle audio systems are becoming increasingly more sophisticated and complex. PAC engineered AmpPRO to dramatically simplify the installation of upgraded amplifiers in data-bus 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!


  • Upgrade solution for factory, fixed level, data-bus controlled sound systems
  • Everything you need in one box to install your choice of aftermarket amplifier(s)
  • Time-saving design, prevents need for summing and audio correction devices
  • Variable volume, fade, balance, bass, mid, and treble audio settings
  • Retains Bluetooth, Navigation, Safety system and all Warning Chimes Audio
  • Front, rear, sub preamp outputs (5 volt RMS)
  • Provides flat audio output for a solid audio foundation
  • Customized OE bass, mid, and treble center frequency selection
  • Plug-n-play installation with 28pin, 10pin and 6pin factory matched harness
  • Remote sub level controller included
  • Reliable PAC quality
  • Optional TOSLINK optical output (APA-TOS1 sold separately)


  • Compatibility
    • Vehicle must be equipped with a JBL system. There must be an actual visible label that says JBL or JBL Synthesis. If the vehicle is equipped with a factory amplifier but does not say JBL, it is not compatible because the amplifier is analog and not digital
    • Lexus vehicles equipped with the Mark Levinson system are not compatible
    • Lexus vehicles equipped with navigation are not compatible
    • Lexus CT200h: Must be equipped with a center channel and a subwoofer
    • Between 2012-2015 Toyota used two different styles of connectors. In order for the AP4-TY12 to be compatible, the radio must have the 10 / 6-pin BHA1761 style connector. Vehicles equipped with the 20-pin BHA8113 style connector are not compatible. The only way to know what connector the radio has is to physically remove it from the dash and look at it. Please see pictures below for reference
