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

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.

Film Capacitors which use polystyrene, polycarbonate or Teflon as their dielectrics are sometimes called "Plastic capacitors". The construction of plastic film capacitors is similar to that for paper film capacitors but use a plastic film instead of paper. The main advantage of plastic film capacitors compared to impregnated-paper types is that they operate well under conditions of high temperature, have smaller tolerances, a very long service life and high reliability. Examples of film capacitors are the rectangular metallised film and cylindrical film & foil types as shown below.

Radial Lead Type
Axial Lead Type

The film and foil types of capacitors are made from long thin strips of thin metal foil with the dielectric material sandwiched together which are wound into a tight roll and then sealed in paper or metal tubes.  These film types require a much thicker dielectric film to reduce the risk of tears or punctures in the film, and is therefore more suited to lower capacitance values and larger case sizes.

Metallized foil capacitors have the conductive film metallized sprayed directly onto each side of the dielectric which gives the capacitor self-healing properties and can therefore use much thinner dielectric films. This allows for higher capacitance values and smaller case sizes for a given capacitance. Film and foil capacitors are generally used for higher power and more precise applications.
