Precision Power DCX 300.2, DCX 500.2 manual Total RMS output X 1.5 = Total Input Wattage

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 performance of your sound system. For more information about charging system upgrades, see you local authorized PrecisionPowerTM Dealer or call PrecisionPowerTM Technical Support at 1-800-62POWER x2033.

CURRENT DRAW

The following is a basic formula to be used as a guide to determine current draw. Your new DCX amplifier is more efficient than most other amplifiers. This formula 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: A DCX amplifier has two channels at 125 watts per channel RMS rating into 4 ohms (125X2 = 250 watts).

You would use the formula in the following way:

500 W X 1.5 = 750 watts

750W = 62.5 Amps total current draw
