over 600 watts ), you are probably exceeding the capability of your
charging system. Dimming lights and fluctuating voltage are solid
indicators that you need to upgrade your alternator, battery, or both.
You should also check the condition and current capacity of the
stock battery negative cable and connections, and replace or
upgrade as necessary. Keep in mind that your amplifiers simply
convert electrical energy to acoustical energy, and any electrical
deficiency will compromise the perfor mance of your sound system.

CURRENT DRAW
The following is a basic for mula to be used as a guide to deter mine
current draw. Your new
DCX amplifier is more efficient than most
other amplifiers.This f ormula is to be used as a guideline.Using wire
of a larger gauge can only improve the current transfer of your
system. Do NOT use smaller wire gauge.
Total RMS output X 1.5 = Total Input Wattage
Total Input Wattage = Current Draw (in Amps)
Supply Voltage
Example:
ADCX amplifier has two channels at 125 watts per
channel RMS rating into 4 ohms (125X2 = 250 watts).
You would use the for mula in the following way:
500 W X 1.5 = 750 watts
750W = 62.5 Amps total current draw
