WHY CAR capacitor?
Powerful modern car amplifiers tend to have great power. A capacitor is a device "storage" of electrical energy. It allows you to instantly add the missing energy electrical circuit. By increasing the volume of car amplifier capacitor instantly produces an electrical charge required for the normal operation of the amplifier at peak loads. Additionally, the installation of the capacitor in the power car audio systems extends the life of electrical equipment.
