How to Buy the Best Audio Capacitor for Your Car


Definition of an audio capacitor: This is an electrical circuit that is used to temporarily store a charge. Do not confuse it with a battery, as the cover temporarily holds a charge. It consists of two metal plates separated by a dielectric.

New types of capacitors on the market are cylindrical, about three inches in diameter and about a foot long. There are also rectangular audio capacitors for various technologies. There are negative and positive terminals that turn the LCD on or off. It doesn’t matter where they come from, but these capacitors are designed for one thing – to store electrical energy.

The best car audio capacitor can charge and discharge very quickly and thus stabilize the voltage across the amplifier. By stabilizing the voltage, it helps the amplifier to reduce distortion and produce more power steadily.

More about capacitors for your car

  1. Audio capacitors can store energy when not needed.
  2. When the energy demand exceeds the capacity of the vehicle’s power system, this stored energy is released by the capacitor.
  3. The capacitor of a car audio system is usually in the range of 0.5 to 3 farads.
  4. Ensure proper functioning of the amplifier.
  5. If you are installing it, make sure it complements your amplifier. And besides that, you also need to place the capacitor as close to the amplifier as possible.
  6. For 500 RMS power output you will need a 0.5 farad capacitor.

Do you need a car audio capacitor?

You have a problem when you see this particular symptom: the headlights are dimmed. If your system has headlight dimming problems, it means a capacitor is needed. Take the hat. This is a pretty good assumption, but it is not always true and certainly not a guaranteed cure. However, it is also important that audio equipment is best installed before installing the capacitor. In this case, you will be able to see which symptoms need to be addressed and assess the severity of the symptoms. This way, you will also know which capacity will be useful.

The market today offers a wide variety of capacitors for your system:

  • For mid-range systems (1000W maximum) you will need a 1 Farad capacitor.
  • For 1000-2000 W systems, you will need a 1.1 to 1.9 Farad capacitor.
  • For 2000 – 3000 W systems, you will need a 2 to 2.9 Farad capacitor.
  • For high power systems (over 5000 W) you will need a capacitor of more than 5 Farads.

An audio capacitor is especially important for high power amplification systems. With a new and improved capacitor connected to the system, your amplifier will perform best at high volume and avoid known side effects such as darkening of light when music is very loud and strong.
