This adapter allows you to add phono connections to the factory head unit (Intellilink R4.0), meaning you can connect a subwoofer or external two channel amplifier. 

In addition to the adapter, the kit also comes with the required REMOTE live wire, this is inserted directly into the grey connector, this is the same way that the factory Infinity SoundSystem amplifier would be activated, meaning under any condition that the head unit is powered up (manually pressing the power button with the ignition off etc) will activate the remote signal wire, this is the correct way to trigger the amplifier rather than tapping off a regular ignition source such as the cigarette lighter.

What's included?

1. Intellilink R4.0 subwoofer adapter
2. REMOTE activation wire

Please note - You will still be required to wire the amplifier directly to the battery as usual for the high amperage feed.
