Top 5 Best Audio Capacitors for Your Car

A capacitor is an electronic component that can take, store, or discharge electrical energy. This action happens quickly, so they are used to buffer or filter any sudden changes that occur with the voltage of a circuit. That results in a smoother signal.

The best car audio capacitors work to prevent the lights of the vehicle from dimming when loud bass tones play over the system. These stiffening caps make this result happen by supplying the amplifier with a fast jolt of power. This action results in better sound consistency because it prevents deterioration.

5 Best Car Audio Capacitors

When shopping for a car audio capacitor, the rule of thumb is to use one Farad of capacitance for every 1,000 watts RMS of total power. There is no penalty if you use a larger value cap. A bigger capacitor helps the system get ready for the next big audio hit. And below are the top 5 best audio capacitors for your car you can buy at amazon:

1. Planet Audio PCBLK2.0

This car audio capacitor offers a two Farad experience for energy storage. It comes with a three-digit bright red digital LED voltage display so that you can always see its status. You’ll receive an audible warning tone if reverse polarity occurs, and there are safeguards in place for low battery voltage or an overload. The working rating for the unit is 20 VDC. It weighs just 3.5 pounds, creating an installation option for almost any vehicle.

You’ll want to make sure that all of the connections are correct according to the included diagram with the product. The capacitor will begin charging, which is a process that could take up to 60 seconds. You’ll see the voltage display stop rising when a full charge is achieved. Then you can take a voltmeter to your battery to know with accuracy that the unit is ready to work. The capacitor does become a little hot when charging.

2. Sound Storm C352 Car Capacitor

You’ll discover a working voltage range of 16 VDC waiting for you with this car audio capacitor. It provides a 3.5 Farad experience for energy storage. You’ll notice the bass enhancement right away with the power stability throughout the system. The surge voltage rating on this product is 24 volts, with a capacitance tolerance of 10% in either direction. Charging can take up to a minute with this unit, but it can also happen in as little as five seconds.

You’ll want to inspect the capacitor regularly to ensure that there is no fluid leakage coming from the top vent. If your car trunk gets hot, the metal foils in the unit to separate some within its electrolytic paste. With careful installation, you can ensure a positive result with this capacitor. You’ll know that the product is charged when the LCD display on the front stops trickling upward.

3. Stinger SPC505 Pro Hybrid Capacitor

This capacitor provides you with a five Farad experience to ensure that you receive a clear and loud bass response from your system. You can monitor system voltage at any time with the front LCD display. It accepts two 1/0ga or 4ga inputs or outputs – or a combination of one each. It features a unique style when compared to the cylindrical designs on the market today, giving the unit more installation options. It can handle a surge of up to 18 volts, working for systems up to 1,000 watts.

You will not need to charge the capacitor before using it, providing users with a true plug-and-play design. It does come with a discharging chip. The size is small enough that you can fit the installation point underneath a seat if needed. You’ll see an immediate stabilization in your car’s system, reducing the issue of dimming lights for most systems.

4. Rockville RFC30F Capacitor

If you need something massive for your car to help stabilize the system, then this 30 Farad capacitor will provide you with what you need. This digital hybrid unit features blue illumination with light following played music. A black wire mesh cover helps to provide more aesthetic value with the installation. The equivalent series resistance is 0.015 ohm at 120 Hz and 25°C. It is built to handle the most power-hungry amplifiers by delivering a surge of 20 volts when needed.

This capacitor features a three-digit bright digital readout to display the exact operating voltage to the decimal point. Heavy-duty bolt-down style platinum-plated terminals allow for a reliable, safe connection. Circuitry controls will alert you if your energy levels get too high or low. Then an automatic sleep feature enables reserve power during volume lulls so that you receive a delivery only when one is necessary.

5. Audiopipe ACAP-6000

This car audio capacitor provides a six Farad experience to give your power systems the stability you need. It adds the extra punch required when you experience dimming issues, although some vehicles might have systems that can overpower this product. You’ll want to be careful with your installation since this tool can charge and discharge so much power that it is capable of welding metal objects like jewelry or tools. Make sure you start the process by disconnecting the ground cable from the car battery.

If you’re running with multiple 2,500-watt subs, then you might need to have two of these units hooked into your system to provide the right level of support. It comes with a robust resistor so that you don’t accidentally overcharge the product. A blue-light LED display lets you see the current output so that you know the exact status of the unit at any time.
