Amperes
The unit of measure for
current or electrical "flow" through a circuit. It is commonly
abbreviated as "amp" and should not be confused with the word
"amplifier," which is also commonly abbreviated as
"amp."

To determine the
approximate current draw (in amperes) of your amplifier (or amplifiers), you
must calculate first the total power of each amp,If you have multiple amps,
add up the total power figures to arrive at a grand total. Next, double your
grand total power figure. Then, divide by 13.8.
The resulting figure is
your system's approximate current draw. Compare this number to the numbers in
the "Amperes" column in the chart below. Cross-reference with the
cable length (the distance from your battery to the amp mounting location) to
determine which gauge of cable you need.
