Use an inline 1A fuse in that wire for protection.
So why would it be an issue to use one of the fuses like I've already done since the fuse panel shouldn't receive constant power? And if this is an issue, would it cause some sort of feedback in the passenger sub like I have sometimes during startup or is this unrelated?
