There is frequently lots of confusion on how to wire a car audio capacitor. There are two terminals on a car audio capacitor. A positive and a negative. The negative terminal is linked to earth. The positive terminal is joined “in-line” with the car audio amplifier 12 volts terminal. Ideally the power capacitor should be as close as possible to the amplifier. In a couple of feet is okay. This keeps any cable losses to a nadir.
An electrical capacitor is placed between the car battery and also the car audio amplifier. An electric capacitor is used to help to provide large amounts of current without creating a big draw to the vehicle’s electrical system. An electrical capacitor will avoid crushing draw in battery and the vehicles alternator and provide maximum performance for your car audio amplifier.
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 one end-of the 4-gauge ground wire to the same place the vehicle audio amplifier is grounded. Connect the other end-of the 4-gauge ground wire to the negative side of the power capacitor and fix it tight using the wrench set.
Fit a 1k ohm resistor in the fuse block in place of the car amplifier power cable fuse. Connect the volt meter to the positive and negative terminals of the power capacitor; the first reading ought to be zero volts.
Connect the power wire to the positive side of the power capacitor and observe the volt meter. After the volt meter reaches 12-volts, the power capacitor is correctly charged. Leave the car amplifier power wire joined to the power capacitor.
Set the 4-gauge power wire onto the good side to the power capacitor as well as the car amplifier power wire. Secure them closely with 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.
