13.2 is about as high as you should set anything, in vehicles with
13.8-14.0 there is typically a 20 ft cable running from the battery to
the radio mount and the voltage drops off in that length. You should
build a crowbar circuit so if the voltage climbs above 13.6 it turns off
or blows a fast acting fuse to protect the equipment, this circuit is
the difference between many home supplies and something you can walk
away from for a few years. Also if the micor is high band you will also
need something to turn it off below 11.0 volts or the pa deck will stay
on overheating and cooking the finals as the current demand goes up when
the voltage drops low, this is a must on a battery backed up system to
prevent the radio from being ruined if the mains are dropped for an
extended period.
