    I am using a 12vdc battery to power an amplifier for my bicycle. I recently purchased a bike 12vdc dynamo to use in addition to the battery to increase the life between charges. I'm using a voltage regulator to keep the output under 13.6 volts but while the bike reaches cruising speed the voltage output does the same, starting off around 3 volts and increasing to 13.6 volts.

    Will the ramping voltage damage the amplifier?

    Since you didn't post any schematics or other detail, I'll take a guess...

    The amp always has the battery supplying it so it won't see the low voltages from the generator, but will run off the battery only during those times.
