Car stereo amps don't draw much power from the battery, but if they are left on and unused for long periods of time, their small drain can add up to a significant amount over time, which means more frequent charging is necessary.
Do amplifiers draw power when off?
Some amplifiers draw current when no remote voltage is applied. 0.045 amps of current shouldn't draw down a good battery unless the vehicle is only infrequently driven. For a daily driver, it's insignificant.
Does a sound system drain battery?
Yes. When a car stereo, radio, receiver, or head unit drains, your battery is due to a process called “parasitic draw.” This term refers to electrical equipment consuming electricity from your vehicle when it shouldn't be (e.g., when the car is turned off or the equipment is not being used).

Do amps draw power?
The average electrical consumption per hour of an amplifier is 100 to 200 watts. To put that into perspective, they use a similar amount of electricity as a refrigerator, slightly more than lights on the ceiling, and ten times less than a standard air conditioner.
Why does my amp keep turning on and off?
There are several different reasons that an amplifier will get hot and shut down. Four of the most common are: Blown/grounded speaker(s), poor power and/or ground connections, too low an impedance (load), or Gain/Punch Bass control settings too high.
