hey george.
the radio on my boat shuts down when i turn the volume or the base up,
it started doing this last season,
i have turned the base all the way down and was able to increase the volume, (somewhat)
it does this with a fully charged battery,
when i turn the river lights on, (with the motor not running)
the radio will power down, (off)
then it will power back up,
the radio is several (5?) years old and was moderately priced,
i do appreciate your knowledge and will appreciate your advice on how to correct this problem,
thanks,
george / waywardson
