You might have heard of the word car audio capacitor before but never fully understand its main function. An audio capacitor acts as a power storage for your car sound system. A car stereo capacitors is also referred to as the stiffening capacitors. The way a capacitor work is it stores power that are utilize by the amplifier and this results into the production of great sound. Because of the audio capacitor, your car audio speakers is able to create a nice crisp and booming bass sound.

Here are some basic facts about car audio capacitors.

The main function of the car stereo capacitor is to store up power whenever it is not being used. The accumulated power inside the capacitor are used up whenever the power system of the car exceeds the available energy supply capacity.

Additionally, this device act as a supplemental power to the car energy system so that uninterrupted power supply are fed to the amplifier at all time. The basic unit of capacitor is in farads. The general range of capacitor that are used up in most car capacitors is between 0.5 farads to 3 farads.

It is important that you install a car audio capacitor that is compatible with the amplifier installed on your car. It is also a common practice to have the amplifier installed adjacent to the capacitor. If your power output is 500 RMS (root mean square) it is important that your car capacitor should be about 0.5 farads.

In addition to a regular capacitor, you can also now buy digital audio power capacitors in which you can also use for your car audio system. These digital models usually has capacitor that starts at 1.5 farads and up. It is also equipped with a turn on and off switch and some models requires a 24-volt DC battery to power it.

You might consider buying a car audio capacitor if you noticed that the brightness of your car lights at nighttime slightly dims whenever your car audio system creates a deep bass note.
