Reasons why car audio batteries require high current

1.Music is not a constant signal, it is full of instantaneous explosive power, such as the tapping of bass drums, explosions, and so on. These moments require audio amplifiers to provide enormous power (current) in a very short amount of time to drive speakers and reproduce impactful sound.

2.High power speakers require enormous energy, and energy (power)=voltage x current. To achieve high power with a fixed voltage, it is necessary to use a large current.

The standard voltage for the electrical system is usually fixed 12V,To achieve high power, it is necessary to increase the current.

If you want the peak power of your audio system to reach 1000W

  • I = P / V = 1000W / 12V ≈ 83.3A

  • This means that at peak output, your audio system needs to draw over 83A of current from the battery and generator! This is only a rough estimate, and in reality, due to issues such as amplifier efficiency, the current may be higher.

3.High performance car audio systems typically use low impedance speakers, commonly 4 Ω, 2 Ω, or even lower.

Ohm's Law: I=V/R

In the case of a fixed voltage V, the smaller the resistance R, the larger the current I.

Driving a 2 Ω speaker requires twice the current as driving a 4 Ω speaker at the same voltage.
