It takes lots of amps to power your vehicle. But when you add big sound power, you need to produce lots of energy to produce no-clip, clean audio. A good rule of thumb is 16-amps of power for every 100-watts of audio output. (If you're into extreme audio, you'll also want an extra battery for every 1000-watts of audio/amplifier draw.)

Stock alternators can deliver only so many amps. And that delivery depends on engine speed. At idle, output is reduced and may not keep up with your sound system draw.
