There’s often a great deal of confusion on how to wire a car audio capacitor. A good and a negative. The negative terminal is connected to ground. The positive terminal is connected “inline” with the car audio amplifier 12 volts terminal. Ideally the power capacitor should be as near as possible to the amplifier. In just a few feet is acceptable. This keeps any cable losses to a nadir.
A power capacitor is placed between the car battery and the car audio amplifier. An electric capacitor is utilized to aid to supply large quantities of up-to-date without causing a huge draw on the automobile’s electrical system. Battery and an electrical capacitor will provide maximum functionality for the car audio amplifier and avoid disastrous draw on the vehicles alternator.
