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 eff ectiv ely
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
dra w for all of them and choose the appropriate gauge based on the
grand total.
PO WER 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.
