I know in some competition car audio systems, guys are running their amps at 16-18 volts. Just wondering if there would be any advantage to this this in a boat? I don't know anything about 16v systems so this might be a really stupid idea. From the little bit of research I've done, the advantages are the amps run more efficient, and put out more power (i could be wrong about this). The disadvantges are having to charge 2 electrical systems(12v for boat and headunit, 16v for amps), and most amps cannot handle above 16volts. It is just an idea I got when I was looking at batteries and came across this one
