I have a 2012 no Nav, No Sony, with Sync. I want to install a sub and run the door speakers off the head unit (for now)
1. Is this the unit I need to run RCAs to my sub amp?
2. Will the sub volume (or bass output) be controlled by the radio volume? and the bass adjustment in stock stereo? or do I need a bass **** installed (in line the rca)?
I am doing exactly what you want to do. Door speakers powered off the factory HU. Installed the PAC and ran RCA to sub amp. On my amp I can tweak the setting on the amp but also connected a remote dial that I mounted under the dash to adjust the bass.
