How Do I Wire My Power Cap

By Eric Glynn

There is frequently lots of confusion on the best way to wire a car audio capacitor. There are two terminals on a car audio capacitor. A good and a negative. The negative terminal is connected to earth. The positive terminal is linked "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 satisfactory. This keeps any cable losses to a nadir.

An electrical capacitor is set between the car battery as well as the car audio amplifier. A power capacitor is used to help to provide large quantities of up-to-date without creating a big draw on the automobile's electrical system. Battery and a power capacitor will provide maximum performance for your car audio amplifier and avoid disastrous draw in the vehicles alternator.

Before you put in a capacitor, you must charge it to stop blowing fuses. Utilize a voltmeter together with a resistor to charge your sound capacitor. You can now wire the capacitor in parallel to your vehicle amplifier.

Remove the inline fuse in the car audio amplifier power cable. Disconnect the power cable in the car audio amplifier using a screwdriver. Slide a terminal connector of the tip of the power wire and secure it to the power wire by squeezing it with the pliers.

Connect a terminal connector to both ends of the 4-gauge ground wire and fasten the ends by squeezing them tight with the pliers. Connect one end of the 4-gauge ground wire to exactly the same place the auto audio amplifier is grounded.

Insert a 1k ohm resistor in the fuse block rather than the automobile amplifier power wire fuse. Join the volt meter for the positive and negative terminals of the power capacitor; the initial reading must be zero volts.

Connect the power cable to the positive phase of the power capacitor and watch the volt meter. After the volt meter reaches 12-volts, the power capacitor is properly charged. Leave the car amplifier power cable linked to the power capacitor.

Slide a terminal connector over one end-of the 4-gauge power wire and fix it by squeezing it tight using the pliers. Put the 4-gauge power wire onto the positive side on the power capacitor along with the car amplifier power wire. Secure them tightly against the wrench set.

Connect the 4-gauge power wire to the to the positive terminal on the amp and fix it tight with a screwdriver. Install the first fuse into the fuse block for that car amplifier power wire. In the event your power capacitor has a digital display, you will see a smaller third terminal on the energy capacitor; this needs to be hooked up to the amplifier's remote wire to turn on the digital display.
