The lower the impedance, the more power they produce and therefore more power from the electrical system. The generator powers the vehicle, all the components and loads the battery. Factory standard alternator is 40 amps to 120 amps, depending on the vehicle. If the generator of high demand or when demand exceeds supply, the ability of generators to start reducing and focus on the reserve battery
Upgraded Alternator
This video is giving us a tutor of alternator for car stereo and audio. This video contains a decrease in amplifier efficiency and an increase in heat due to decreases in voltage and increases in amperage. This is very hard on the alternator and amplifiers in the system and why an upgraded alternator is vital when upgrading your audio system.
