Kicker KX200.4 technical manual Power Cable Calculation, Power Wire Chart

Power Cable Calculation

(Total RMS power output into 4Ω) x 2 = (Total input wattage [Watts])

(Total input wattage)

= (Maximum input current [Amps])

(Supply Voltage)

Example: Amplifier with a rating of 100 watts per channel into 4Ω 200 x 2 = 400 Watts (Total input power)

400 Watts / 12.5 Volts = 32 amps (Total maximum draw) Use this value of current draw to determine wire size from the chart below.
