One more question - Bose Nav
 

So after looking at the wiring diagram for the Bose with Nav. It looks like there isn't any inputs that are for the subwoofer, total of 4 inputs (front left/right, rear left/right). My plan is to just use the front inputs from the headunit/nav to feed both the front input on the LOC along with the sub input on the LOC. I am hoping to get a clean signal this way. Do you gentlemen think there will be any issues with this? Its my first time using an LOC. Thanks again.

You can just use a RCA Y splitter and split the rear channels.
