Also asked, how many amps does it take to run a car stereo?
A typical stereo head unit will need about 5 amps of power. If you want to crank up the volume for parties and plan on using a powerful amplifier, then 5 amps likely won't be enough either. We do have power supplies available that offer up to 30 amps.
how many amps does a 1000 watt amp draw? Watt = Volts * Amps so if the amp is putting out 1000W RMS and uses a 12V supply then it requires 83 Amps. There are two other factors to consider. The amp is not 100% efficient so assume 50% efficiency and you have 166 amps. Then because the 1000W is peak, derate to 1/3 of that giving you about 55 Amps.
Just so, how many amps does a car amplifier draw?
You need to start with your given power (power is measured in watts) so your amp puts out 300w with what, 13.8v of potential voltage? So your amplifier, with your charging system sitting at 13.8 volts, puts out 300w, and your current draw of your amplifier is 21.74 amperes (amps).
How many volts does a speaker use?
Since the amplifier is at the same location as the speaker, the speaker requires only a line level audio signal as an input. Line level signals are typically around 1-2 volts, and can be transmitted over much smaller cable (typically 20-26 AWG).
