wires as close together as possible, and use the same gauge wire
for both. This will ensure that you have a good ground path, and may
eliminate such potential problems as engine noise and overheated
amplifiers.
CHARGING SYSTEM
If your total current draw is over 100 amps (
or total output power is
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 performance of your sound system.

CURRENT DRAW
The following is a basic formula to be used as a guide to determine
current draw. Your new 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 1.3 = Total Input Wattage
T
otal Input Wattage
= Current Draw (in Amps)

Example:
A PPI
amplifier has one channel at 1000 watts RMS
rating into 4 ohms.
You would use the formula in the following way:
1000 W X 1.3 = 1300 watts
