The Best Car Audio Capacitors You Need To Know

If you love listening to music every time and everywhere, you probably have heard of a car audio capacitor. It is fundamentally a device that stores alternative current and only consumes, not create energy. That’s why it can adjust a stable and constant power running to your amplifier and make the entire audio system work smoothly.

With music lovers, it can be considered the best tool to produce a high-quality sound.Although it is quite essential, I still see many people not realize its importance. And even if they do, they still don’t know how to use it and which one to choose when buying. Therefore, in this article, I will show you how to charge a capacitor, the most basic skill, and recommend some of the best ones. If you are having troubles with those, I believe you will discover the most useful solution after reading.

The Best Types You Need To Know

1. PYLE PLCAPE50 5.0 Farad Digital Power Capacitor

Best Car Audio Capacitors, PYLE PLCAPE50 5.0 Farad Digital Power Capacitor

Power at a high speed is what I need to say about this product. It was the first capacitor I had a chance to use, when I still had my old Ford Fiesta. Its audio system was great and provided wonderful sound, but it was quite slow. I did not know why but perhaps, the power from the amp was not as strong as I expected when buying the car.

This capacitor had fixed everything since I purchased it. The time for the whole system to work was shortened to only 1 second, while it was about 5 or 10 seconds without the capacitor. Furthermore, it keeps your car battery charged all the time and is very easy to install.

Although I no longer keep it because I sold that car, it’s still one of the most high-quality capacitors I had ever used. If you have a low power amplifier or tired of the slow pace system, this capacitor will be just perfect.

2. Power Acoustik 2.0 Farad Digital Power Capacitor

Best Car Audio Capacitors, Power Acoustik 2.0 Farad Digital Power Capacitor

This second one is for busy people, who like to use it for good without adjusting or replacing. Because it is very durable, you can use it without any replacement after the first time installing. My friend, Edna, had one just like this and she had been using it for more than 5 years. It had still been working well until now.

I guess its chrome cover along with plated finish were the crucial features for durability and a stable outlook. Edna’s light became brighter than ever and never dim again when she had it. And if you buy it, you won’t need any remote cable. The capacitor had a feature of shutting off automatically, so you won’t even have to touch to turn it off.

It will shut whenever you turn your key.I like this product because of its amazing durability and strong current that it can handle. If you don’t have time to pay attention to the capacitor much and only need one for conveniently turning off, I believe this Power Acoustik 2.0 is the right one.

3. Rockford RFC 11 Farad Power Capacitor

Rockford is a quite popular brand, which has created various electronic products. Capacitors are also one of their primary best-sold items. And I think this RFC 11 was produced aiming at providing the best sound quality for the user. It is also my most favorite capacitor in this list and I am still using it now.

If you love music just like me, it will boost the sound to such a whole new level. Deeper and stronger bass, as well as a clear and high-quality sound will definitely satisfy you. Particularly, even if you have a subwoofer, the bass it creates will still be stable and produce a wonderful beat.

You will become the king or queen of any outdoor parties you join in. Besides, this capacitor is plated with platinum and has a solid design with brass top and hardware. Therefore, it can stand significant impacts no matter terrains your car is running on. If you have an off-road vehicle and still want great music on the way, this capacitor is worth the money.

4. Soundquest SQCAP2M 2 Farad Power Capacitor with Digital Display

I bought this one for my father about a month ago on his birthday. He likes listening to music as well, especially Mozart. Nevertheless, his car was quite old and gave irritating engine noise. That’s why this capacitor was perfect because it could reduce that to the minimum level. It had a so fantastic sound filter that you will hear only the music when the glass windows are closed.

Even when there was a heavy rain or uncomfortable weather conditions, the sound would always remain its quality. Furthermore, this product looked quite small and light, so it was the most appropriate choice for limited space in my dad’s car. Screws, wrench, and solid brackets were also my most favorite features. It showed obvious number so there were no difficulties for my dad to see and adjust it.

If you have a small car and need a clear sound quality as well as to save rooms, or you need something as a gift for your father and granddad this Christmas, this capacitor won’t disappoint you.

5. New VM Audio SRCAP2.0 2 Farad Car Hybrid Digital Power Capacitor Blue LED Cap

New VM Audio SRCAP2.0 2 Farad Car Hybrid Digital Power Capacitor Blue LED Cap, Best Car Audio Capacitors

I had a chance to test this product at the store when I went to buy a capacitor. Its high surge protection was what impressed me most. It can protect the whole amplifier and speaker system even when the volt is up to 20.

In fact, you will hardly ever use it with 20 volt, but it’s still safer if it can withstand a high level electric current like that.Its LED display was also one of its unique characteristics, which is only turned on when the volt got too high. Therefore, it’s a perfect support tool for your battery and an adjusting part for your audio system.

If you don’t have a high demand on sound quality and need something stable and secure, you can try this capacitor. I think it would bring the greatest using experiences ever.

How To Charge A Capacitor?

After cutting the power and wiring your capacitor, there are two ways to charge it, which are with a resistor and test light. With a test light: This is the simplest method to charge a capacitor. Hook the power and ground cable of your test light to the terminals in which your fuse used to be plugged. Remain the position until the light bulb turns off.

That’s when it reduces from 12 volt to 0 volt, which means the capacitor is fully charged.With a resistor: Using this tool is a little more complicated, but not so difficult. Just hook up its positive lead to the same terminal on the capacitor and the negative one on the negative terminal. Wait until the number 11 or 12 appears on it. Then, feel free to replace it with your car fuse.For further instructions, you can watch this video:

These methods are not too hard to apply, aren’t they? You will learn them in no time. Don’t worry!


I hope all of the information I provided would be useful to you when choosing a capacitor. I had the most appropriate one after I made my decision, so I hope that you would have the wisest choice as well after reading.
