AHAHHAHAH This is a funny, and very common problem on people who install there own radios.
No intent to flame or anything but dude if you would have followed the instructions on how to connect the Opus you wouldnt have this problem. Your problem is the yellow and red wire connected to the same source.
Added: Put that switch in the remote line. Turn the switch on, it will sense 12v and turn on. Turn the switch off, no 12v and it will shutdown.
Shame on you.
