The PAC AmpPRO SUB APSUB-CH42 subwoofer amplifier interface gives a compatible factory audio system a clean, controlled preamp signal for an aftermarket subwoofer amplifier or powered subwoofer while keeping the original radio and supported factory audio functions.

At a Glance

  • Vehicle-specific interface for adding bass to a supported factory amplified audio system
  • Two non-fading subwoofer preamp outputs with selectable 4- or 5-volt RMS level
  • Includes a wired level control for adjusting aftermarket subwoofer output from the front seat
  • Provides a data-controlled remote turn-on output for the aftermarket amplifier
  • Retains supported factory radio controls, chimes, prompts, Bluetooth and communication audio
  • Aftermarket amplifier or powered subwoofer, power wiring, RCA cables and installation materials are sold separately
