## How much power does an amp draw?

Power supply schematic shows a 1 amp fuse.

The maximum amount of power it can draw would be limited by that.

If your AC is 120v then multiply that by 1 amp to get 120 watts.

Under normal operation it may vary from 2-5 watts up to maybe 100 watts at full volume..

## How many amps do I need for my car audio system?

In most cases, you’ll want one amp for all the speakers in the car, which means you’ll need multiple channels on the amp — each channel drives one speaker. Since most cars have four speakers, four-channel amps are the most popular. Five- or six-channel amps will give you even more options.

## How many watts does a car amp need?

Standard factory car stereos usually have no more than about 10 watts RMS maximum output power per channel, in spite of what the car dealers advertise. That’s usually not enough power to overcome road noise without sounding shrill.

## How many watts can a 20 amp fuse handle?

For standard 120-volt service, a 20-amp breaker can support up to 2,400 watts on a single circuit. However, circuits should not be loaded to greater than 80 percent of their maximum capacity for long periods, which makes 1,920 watts the safe maximum for a 20-amp circuit.

## How many amps does a remote wire draw?

Don’t go pulling a crap load of current though. But with the small fans you’ll be good. Most head units can only handle about . 5 amps of current draw on the remote line, so like others have said, use the relay.

## How do I convert watts into amps?

Amps calculation with line to line voltageI(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.amps = watts / (√3 × PF × volts) or.A = W / (√3 × PF × V) Example. … I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.
