What size amp do I need for 2 600 watt subs?

What size amp do I need for 2 600 watt subs?

What size amp do I need for 2 600 watt subs?

So you have 2 600RMS subs, so you need an amp that does 1,200RMS.

How do you measure the wattage of an amp?

Power = Voltage squared divided by Resistance. With a constant sine wave input, you measure 10 volts AC on the speaker output of the amplifier. Since you know the resistance (5 ohms) and the voltage (10 volts), you can calculate the power: Power = (10 times 10) divided by 5 = 100/5 = 20 watts.

What voltage should my amp be?

Usually the range is somewhere between 10.5-16.5 volts. A regulated power supply will put out the same power regardless of the vehicle voltage. So even if your vehicle’s voltage drops to eleven volts it will still put out the same power as if the vehicle’s voltage was fifteen volts.

How to determine amperage needed?

First,find the breaker that correlates to the electrical device you are using (This is normally either a 15-amp or 20-amp circuit).

  • Multiply the amperage by 0.8. This is because a circuit breaker should never exceed 80% of its max amperage.
  • Calculate the amperage draw of ALL the devices you wish to plug into the circuit.

    • How to measure Amps in a household electrical circuit?

    Turn off the power to the circuit. If your circuit is powered by a battery,unplug the negative lead that’s running from that battery.

  • Disconnect the red wire coming from the power supply. In order to test the amount of current flowing through a circuit,you have to attach the multimeter so it
  • Strip the ends of the wire,if necessary.

    • What is the formula for calculating amperage?

    Ohms calculations

  • Amps calculations
  • Volts calculations
  • Watts calculation

    • What is the equation for amps?

    83.3 amps at 12 volts

  • 41.6 amps at 24 volts
  • 20.8 amps at 48 volts
  • 8.3 amps at 120 volts
  • 4.1 amps at 240 volts
