Hey guys-
I've added subs to PLENTY of vehicles using the factory head unit before, but this one is giving me a heck of a time!

NORMALLY I would put an aftermarket head unit in, but this is a work truck so I'm just adding a sub to it.

I have all the power, ground and remote wired up so the amp comes on with the key, but I am still getting no sound, even with a Line-out converter.

Does anyone know what wires I need to tap into for the line-out converter?

It is a 2013 Chevy Duramax 2500, with factory Nav Touch screen and the Bose factory system.

Anyone out there able to help me?
