How many amps does a 2,000-watt car amp draw?

How many amps will my new 2,000-watt car stereo amplifier draw? I’m worried that it will drain my battery quickly.

Liz Jenson · Updated on Nov 29, 2021

Reviewed by Shannon Martin, Licensed Insurance Agent.

Usually, a 2,000-watt car amp will draw about 159 amps. However, this assumes that your car battery is fully charged and operating at 12.6 volts. Amps are calculated by dividing the wattage (in this case, 2,000) by the voltage (which is assumed to be 12.6). If your car battery operates at a different voltage, calculate the amps using that number.

A typical 12-volt car battery can produce up to 600 amps, so installing the amp in your car shouldn’t have a drastic impact on your car battery. Just try not to leave your

running when your engine is off!
