I only ran the input, amps, and remote wire over to the battery area. the power and the ground to the helm bus
The remote will allow you to turn the unit on when you turn your stereo head unit on. Similar in that your amps turn on when you turn your head unit on.
I just ran the red to the stereo switch but am considering changing it to the bus as it causes a slight pop if turned off before the head unit is turned off.
