Many car audio enthusiasts ask about the importance of car audio capacitors to their overall car audio performance. If you have a high powered system or your amplifier doesn't get enough power, probably you need a capacitor. Making sure you have a capacitor installed will prevent any damages to your amp and other audio components.

What is the main role of a car audio capacitor?

Unlike automobile batteries, the main function of an audio capacitor is to store energy. This stored power will be used on demand (when your amp needs it). This will ensure that your audio system is being used to its maximum capability.

How do I know that I need an audio capacitor?

The first thing you will notice is dimming lights. The light will get weaker each time a heavy bass note sounds. If you installed the right capacitor, your audio system would have received the right amount of power needed.

What type of a car audio capacitor should I buy?

Depending on your system, but generally speaking:

- For mid-level systems (1000 watts maximum), you need a 1 Farad capacitor.
- For 1000 - 2000 watt systems, you need to get 1.1 to 1.9 Farad capacitor.
- For 2000 - 3000 watt systems, you need 2 to 2.9 Farad capacitor.
- For high power (over 5000 watt) systems, you need 5+ Farad capacitor

Keywords: Polarised, DC power supply circuit, large capacitance.

Electrolytic Capacitors are generally used when very large capacitance values are required. Here instead of using a very thin metallic film layer for one of the electrodes, a semi-liquid electrolyte solution in the form of a jelly or paste is used which serves as the second electrode (usually the cathode). The dielectric is a very thin layer of oxide which is grown electro-chemically in production with the thickness of the film being less than ten microns. This insulating layer is so thin that it is possible to make capacitors with a large value of capacitance for a small physical size as the distance between the plates, D is very small.

The majority of electrolytic types of capacitors are Polarised, that is the DC voltage applied to the capacitor terminals must be of the correct polarity, i.e. positive to the positive terminal and negative to the negative terminal as an incorrect polarisation will break down the insulating oxide layer and permanent damage may result. All polarised electrolytic capacitors have their polarity clearly marked with a negative sign to indicate the negative terminal and this polarity must be followed.

Electrolytic Capacitors are generally used in DC power supply circuits due to their large capacitances and small size to help reduce the ripple voltage or for coupling and decoupling applications. One main disadvantage of electrolytic capacitors is their relatively low voltage rating and due to the polarisation of electrolytic capacitors, it follows then that they must not be used on AC supplies. Electrolytic's generally come in two basic forms: Aluminum Electrolytic Capacitors and Tantalum Electrolytic Capacitors.

If you always purchase many kinds of film capacitors, or electrolytic capacitors, you should know how to test the capacitors.
1. Remove the suspected faulty capacitor from the unit. If it's a high powered capacitor, it will still hold a high charge. Discharge the capacitor by using a metal screwdriver with a handle that's insulated. Touch the metal end of the screwdriver to both metal terminals at the same time to discharge any power left in them.
2. Turn on the capacitor tester and make sure it's getting power. Plug in the tester probes according to the instructions on the meter. Set the selector to an OHM scale before testing the capacitor. Some meters will have an OHM setting pre-set for you.
3. Touch the leads together so that the meter will zero out by adjusting the wheel on the meter
4. Note where the meter points to before touching the wires to the capacitor. Then touch the terminals of the capacitor with the red probe, which will go on the left, and the black probe which will go on the right.
5. Watch the pointer on the meter. The needle should move away from the left side, or the infinity, and veer toward the right before returning to the infinity. It should move further to the right when the probes are reversed. This means the capacitor is good. If the needle goes all the way to the right side and doesn't return to the left, or infinity side, the capacitor is bad, or it has shorted out.
