If the same amplifier is driven into a 2 ohm stereo or 4 ohm mono load, double it’s 4 ohm RMS rating. All DCX amplifiers will effectively double their power at this load.

500W X 1.5 X2 = 1500 watts

1500W = 125 Amps total current draw

12V

If you are using more than one amplifier, add up the total current draw for all of them and choose the appropriate gauge based on the grand total.

POWER WIRE SIZE

A minimum of 8 gauge or a maximum of 4 gauge wire is recommended dependent on the application.

The ground wire must be the same gauge as the power wire.
