This is more of a technical question, but I wouldn't personally do such a thing. Remote turn on wire should be wired to your HU. I'm surprised the technicians didn't advise the same or as well.. good luck tho

You can, but I would find a wire that is controlled by the vehicles ignition, with a fuse. If you do use the battery at lease use a fuse.
