PAC AmpPRO SUB Advanced Amplifier Interface GM 2014-2019

SKU CH-XJM3-HEMXN

Adds and controls an aftermarket subwoofer amplifier in select 2014-2019 GM vehicles with RPO IO5 or IO6 infotainment systems

  • Product typeAmplifiers
  • Seamless factory integration via databus connection
  • Add aftermarket subwoofer amplifier with full control
  • Preset EQ optimizes factory sound settings
  • Eliminates need for audio correction devices
  • Compatible with 2014-2019 GM vehicles with IO5/IO6

Vehicle Compatibility

The PAC AmpPRO SUB interface is designed for select 2014 to 2019 General Motors vehicles equipped with the factory infotainment system carrying RPO code IO5 or IO6. It provides an upgrade path for fixed-level, databus-controlled sound systems by allowing the addition and control of an aftermarket subwoofer amplifier.

Installation Experience

The timesaving design eliminates the need for separate audio correction devices, streamlining the integration process. Installers must verify the specific RPO code before beginning work, as the interface will not function with other factory radio configurations.

Target Buyer

This unit suits GM owners who want to add a subwoofer amplifier while retaining full factory radio control and optimized equalization. Buyers whose vehicles lack the IO5 or IO6 infotainment system, or who drive models outside the 2014 to 2019 range, cannot use this interface.

Questions about this item

How do I verify the AmpPRO SUB interface is communicating with my GM databus after installation?

The interface is preset and equalised to integrate with factory EQ settings; once powered, the factory radio retains full control and sound output should remain balanced without extra correction devices.

What comes in the box with the PAC AmpPRO SUB Advanced Amplifier Interface and what must I purchase separately?

The package provides the integration module for select 2014 to 2019 GM vehicles with IO5 or IO6 infotainment; an aftermarket subwoofer amplifier and wiring are not included.

Which version of the AmpPRO SUB should I choose for my 2014 to 2019 GM vehicle?

This single model covers compatible GM vehicles from 2014 to 2019 that have RPO code IO5 or IO6; confirm your infotainment code before ordering.
