subwoofer wire to radio

[Bosch]

I wonder what wire goes from the sub to wich OEM harness.

I have 2012 Avalanche with the Bose stereo and installed a aftermarket Pioneer AVH-Z9200DAB radio. I'm not sure if the sub is connected. These harnesses are left over after the install. Maybe sombody knows what these are for.

Stock sub is not connected to any of those harnesses in the picture.Did you pull those out of the Bose amp? If so they are just signal or data wires.

I dont know were they are from since the previous owner had allready installed a aftermarket Pioneer. And left these one hanging. So my question is, what are these harnasess for. I already know that one is the antenna, one is probeble the usb port in the centre console. The brown one is for the backup camera. My guess is that the bleu one is for the navigation.
