hello
i would first un hook your amp and take it for a spin if the problem goes away then thats it.if not i would look into you alternater

When a battery drops voltage, even a small amount, it makes a big difference. For instance, when a battery drops from 12.6 to 12.0 volts, its power drops from 100% to 25%. At 12.4 volts, a car battery is only 75% charged. At 12.2 volts, it is only 50% charged!

A car battery is considered charged at 12.4 volts or higher. It is considered discharged when it is 12.39 volts, or less.
Where is yours:confused:
