Interesting Qualities of the Best Car Audio Capacitor
A capacitor is an electronic device with two plates separated by an insulator. This device collects and stores power just like the battery.
The value of the capacitor known as capacitance is determined by the overall surface area of the plates and its distance between the two plates. The term used to describe the capacitor’s capability to store energy is known as Farad.
Finding the best car audio capacitor is not that easy. You need to consider several factors before you decide which capacitor to buy. Capacitors are typically available in cylindrical shapes that are 3 inches in diameter and one foot long. There are capacitors which are rectangular in shapes but used in different technologies.
It has negative and a positive terminal and a third remote turn on terminal that converts an LCD display on or off. Regardless what shape they come they are designed for one purpose, to store electrical power. Here are 3 of the best power capacitor for car audio that you can consider.
13 x 9.5 x 3 inches
10 x 5 x 2.5 inches
12.5 x 4.2 x 3.2 inches
What to Consider When Choosing a Car Audio Capacitor
1. The Size
The accepted rule since the time car audio power capacitor was introduced has been one Farad of capacitance per 1,000 watts of power having one Farad as the minimum. More than the said value is not necessary but it does not hurt either.

2. The Capacity / Capacitance
In choosing the best capacitor for your car, you will encounter the term capacitance. It refers to the diameter of the capacitor. You should keep in mind that the larger tank can hold more water. This means that the larger tank can hold more electrons as well.
3. The ESR or Equivalent Series Resistance
Normally, a capacitor would only have capacitance. As you know, all conductors have resistance. There are multiple conductors in a capacitor lie the foil, the electrolyte and the wire leads. The ESR contributes to the capacitor’s resistance. It is just like having a resistor in series with the right capacitor. Those with high ESR will have less capability to pass electricity from its plates to the external circuit. If you are using a capacitor as a filter choose the one with low ESR.
4. The Working Voltage
Another important characteristic of a capacitor is the working voltage. This defines the maximum continuous voltage either AC or DC that can be applied to the capacitor without failure on its working power. Generally, the working voltage is expressed in WVDC or working voltage DC which is printed on the side of the capacitor’s body. Any excess DC voltage of its working voltage may cause failure. The common DC voltages are 10V, 25V, 16V, 63V, 1000V, 50V, 35V, 400V and 200V.
5. The Tolerance (+%)
The tolerance in capacitors is expressed as plus or minus value generally less than 100 pF. The capacitors are rated based on how near to their actual values they are compared to the rated nominal capacitance with colored letters or bands used to indicate actual tolerance. The most common tolerance value is either 5% or 10% but there are some that are rated as low as ±1%.

What is the Best Capacitor for your Car?
When it comes to choosing the best car audio capacitor, you need to think about the important features of the capacitor. If you are looking for a capacitor with higher Farad or capacitance BOSS AUDIO CAP8 8 Farad Capacitor is a perfect choice. At 8 Farad it can hold enough water and electron to provide the needed power. The Boss audio also has the best tolerance as compared to the other two capacitors.
But if you are looking for a smaller capacitor then choose the Power Acoustik PC1.5F 1.5 Farad. The Power Acoustik can still provide the required power for continuous functioning of your audio system.
