I have a Powermax 100 amp and plan on using it with my RCI2970N3. Still looking for the best voltage to set it on for safe use either the radio. This is like a mystery it seems. I have it set to fixed output not charging. I think I eould rather the fan run all the time than just come on when it starts getting . What voltage do most run for their 300+ watt radio like a RCI2970N3
RTFM for the radio equipment for the best voltage to set it at.
