Amplifier Current Draw...
The following basic formula can be used as a quick guide to determine the
total amperage draw of a mobile audio system. This formula is based on a 50%
amplifier efficiency rating. Diamond Audio D5 amplifiers are more efficient.
Others may be less.
Formula:
Total amplifier rated RMS power divided by .5 = Total Input Wattage
Total Input Wattage = Current Draw (in Amps)
Battery Voltage
Example:
An D5 600.4 amplifier has 4 channels at 75 Watts per channel RMS into 4 Ohms
totaling 300 Watts. Work the formula as follows:
300 Watts / .5 = 600 W
600 W = 50 A Total Current Draw
12 V
If the same amplifier is being driven to a 2 Ohm stereo or a 4 Ohm mono load,
double the total wattage number:
(D5 600.4 = 600 W @ 4 Ohms Mono) / .5 = 1200 W
1200 W = 100 A Total Current Draw
12 V
Note: If you are installing multiple amplifiers, add up the total current draw
for all of them and choose the appropriate gauge based on the grand
total.
TURN-ON CONNECTION (REMOTE)
Locate the terminal labeled "REMOTE" between the ground and +12V power
connection points on the end of the amplifier. Your source unit should have a
wire in its harness labeled "REMOTE" or "AMP TURN-ON." Some source units
come equipped with a "Power Antenna" lead only. This should also work. Run
this wire from your source unit to the amplifiers REMOTE connection. Strip
approximately 1/2 inch of insulation from the wire. Insert the wire into the
terminal, and tighten the Allen screw. Your D5 Professional Reference Series
Amplifier will accept remote turn-on wire up to 10 gauge directly.
