I have an Alpine 7525 car radio. Can you tell me what (approximately) is the normal current drawn with zero volume? Or better still, where I might get a copy of the service manual. David Brown
The current used by a car stereo is calculated by dividing its wattage by 12, which is the standard voltage for cars. This calculation is called Ohm's Law. For example, if a stereo is rated for 100 watts, it uses 8.333 amps of current.
