Wattage Chart

Choosing which battery to use to power your audio system can be daunting when faced with all sorts of numbers and specifications that don’t seem to have anything to do with car audio at all. With our wattage chart below, the choice has never been easier! When using only one battery, refer to the “Primary” column; when using a second battery as a supplemental battery, refer to the “Secondary” column. When replacing the original battery and adding supplemental power, use a combination of the two columns to arrive at the desired level of power needed to satisfy any stereo system!
