2 questions, does a head unit draw the majority of its power from the ignition wire or the constant wire? Second question, does the head unit draw power from the ignition wire once started?

Thanks

Majority of power comes from the constant wire...certainly it is the bigger wire that draws more power...

And yes, the ignition wire does draw power from the ignition wire once started.
