I work in a network company as a customer service.I've heard the question asked many times before, 'Do I really need a capacitor?' Before answering that question I ask, 'Do you have a high powered system?' 'Does it require sudden power bursts?' 'Is your amplifier being robbed of power?' If the answers to my questions are yes, make every effort to connect a capacitor to your car audio system.
What is a capacitor?
A capacitor can be used like a temporary battery,because it can store electric energy when disconnected from its charging circuit.Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)
A capacitor is an electrical/electronic device, and its ability to store electrical energy is termed capacitance.The capacitor can be fixed or varied by switching discrete capacitor segments in and out as dictated by system conditions. This specification is applied to the capacitor ohich are used to across-the-line for the appliance.
So, as you know a capacitor is a bit similar to car battery; it stores electrical energy. But unlike a battery it doesn't produce its own power, it simply stores it. A car audio capacitor will help you get the most from your amplifier. It will store power for release on demand, delivering it to your amplifier just when it's needed.
Your car amplifier requires a lot of power to play loud music, especially when there's lots of heavy bass. Without a capacitor your amplifier will be robbed of power by parts like your lights, engine, and air conditioner.
So what happens when your car audio amplifier doesn't receive enough power?
A common occurrence is dimming lights. In such a situation the light will follow the beat of the music. The light will dim each time a heavy bass note sounds. If you were to turn off the lights, your car stereo system would suddenly sound louder and the music would be cleaner.
Your amplifier is simply trying to use more energy than the electrical system can supply. If a capacitor had been present there would have been enough energy to power your amp. That electrical energy would have already been stored.
When you want to reduce headlight dimming, improve bass response, and increase the power of your amp, a stiffening capacitor is a must. Equipped with capacitor and an adequate power supply, your system will get every bit of current it needs. Voltage drops will be a thing of the past.
Have a capacitor. No longer will your car amplifier be hungry for power.
