How many amps does a 12v amplifier draw?

The problem with using some type of transformer is not that it puts out 12v but its the amperage. A typical car amplifier requires anywhere from 10-30 amps.

What size amp do I need for 2 12 subs?

RMS power handling of a 55 series 12” dual 2 ohm voice coil subwoofer is 400 watts. Two of these subwoofers would mean you need 800 watts of power at to the total circuit impedance.

What size amps do I need?

Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.

How do I know what size amp I need for my subs?

Find out the “watts RMS” rating of the sub. Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating.

How many amps does a 1000w amp draw?

Watts To Amps Table (At 120V)

Watts:	Amps (at 120V):
800 Watts to amps	6.67 Amps
900 Watts to amps	7.50 Amps
1000 Watts to amps	8.33 Amps
1100 Watts to amps	9.17 Amps

How many amps does a 1200 watt car amp draw?

1200 watts is 100 amperes at 12 volts, and 10 amperes at 120 volts. (power = volts x amperes) So we also need to know that. It should give you that information on the back of the amp. 10 amps would be a good guess but that also depends on the class of the amp.

What is the formula to calculate Amps?

To obtain Amps you need both Watts and Volts: The formula is (W)/(V) =(A). For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A. This comes from the equation I = P / V. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

Is a 1200 watt amp good?

In some cases, a 1200W budget amp could be a viable choice. For example, if you need a cheap amp to run you four 30W (or even 50W) speakers, a cheap 1200W amp can do the job just fine.

How many watts is 6 amps?
