When updating your stereo system, How to Charge a Car Audio Capacitor, this question also rises you have to add a capacitor to your car stereo system.
Without having a capacitor, the amp can bring out a lot of power from the battery and evacuate it too arid to power up your car, lightning, and other characteristics. Note that these capacitors do not come charged, as they may lead to a voltage surge as soon as the installation occurs.
On the other hand, you can also not add an empty capacitor. It can lead to an abrupt current inflow, which can result in sparks, and it will be dangerous not only to the capacitor but also to the other electronic components and your entire audio system.
Curtly, a capacitor has to be charged before it’s installed in your audio system. Although, it is not very complicated to charge the capacitor. To keep your audio system safe and sound, you have to know how to charge a car audio capacitor.
If you don’t know, here in this article, I am going through the details and general steps to charge your capacitor on your own without the help of an expert.
So, let’s get started without any delay!
How a Capacitor is Helpful for Your Car Audio?
Capacitor assists in preventing straining the battery. Having a capacitor in your audio system can prevent an imbalance of the power supply and the malfunction of several car systems.
If your amp is consuming a lot of energy and does not carry a capacitor, then, in that case, you may come across dim lights and poor visibility whenever you play a song in your vehicle.
As you know, the capacitors take less duration in charging and store less power as pertained to batteries, but you can charge them at the maximum level; for example, an ordinary 12V battery can charge the capacitor to no surplus than 12V and can get the best out of them.
Which Items do you Need to Charge a Capacitor?
However, there are not any special items that you will need while charging your capacitor. A few are the main ones that become handy when charging a car’s audio capacitor, like capacitors, power wires, connectors, wire crimpers, a memory saver, and pliers.
Steps to Charge a Capacitor
As a general rule, there are some steps to charge a car audio capacitor:
- Park your car on the steady ground and apply a hand brake.
- Plugin the memory saver.
- First, unplug the ground wire starting from the negative terminal. You can’t collect negative terminals to your car stereo system.
- While charging your car capacitor, connect the positive terminal to the positive terminal in your car’s battery.
- Don’t forget to add a resistor between the positive terminals you wired before.
- Now, time to connect the negative terminal to the ground and covering and not at a similar place as the amplifier.
- If you charge it without a resistor, the voltage across it must be more than its relevant voltage
Now, let me brief the process regarding how to charge a car capacitor with the charging tool and without the charging tool.
Charge a Car Audio Capacitor with a Charging Tool
Some audio capacitors are available with a charging tool that makes it easy to charge your capacitor on your own. This charging tool is virtually an acreage accentuating a resistor and four wires, two positive and two negatives. I am writing the steps below on how to charge a car audio capacitor with a charging tool.
- Attach one positive and one negative wire with the related terminals of the capacitor.
- Attach the second positive wire of the charging tool with the positive terminal of your car battery.
- Attach the second negative wire of your charging tool to the car casing to ground it. Take a note here that don’t make a common ground between the charging tool and the stereo system.
- As soon as the second negative wire is grounded, your capacitor will start charging.
- Bring out the multimeter and compose it to calculate the direct voltage.
- Wait for 2-3 minutes, and put the probes on the edge of the charging tool to receive the voltage reading. You will see a gradual increase in the reading of your capacitor charging.
- When the millimeter shows the 12V or stops the increase in reading, it indicates that your capacitor is fully charged. Now, it’s the time to remove your charging tool’s ground and then the other wires you connected.
Charging a Car Audio that is available without a Charging tool
Some capacitors in the market come without a charging tool. I’ll tell that how to charge a car audio capacitor without a charging tool.
Here is a solution for that, too. You can use a 12V test light bulb to charge your car’s audio capacitor. Consider the following steps while looking for how to charge a car audio capacitor without a charging tool.
- Attach the negative terminal of your capacitor to the casing to ground it.
- Attach the wire to the +ve terminal of the battery and relate its other edge to the initial edge of the test bulb.
- Attach the wire to the +ve terminal of your capacitor and relate its other end to the second terminal of the test bulb. The test bulb will be brightened. It will remain to brighten for a few minutes. When it stops brightening, it is an indicator for you that the capacitor is fully charged.
What if the Car Audio Capacitor is not Charging?
Now that you know how to charge a car audio capacitor let me tell you if your audio capacitor is probably not charging because it is not in a complete circuit.
Your circuit needs a source of power, load, and a way to flow current. In case your capacitor is harmed, the best advice is to make a replacement of it.
How much Time will it take to Charge a Car Capacitor ?
Charging time may vary on its size, but on average, it takes hardly 5 minutes for a car capacitor to be fully charged.
How to Charge a Car Audio Capacitor?
I hope this article is enough to help you with how to charge a car audio capacitor. Hopefully, you will use this guide to be aw how to charge a car audio capacitor safely.
Although, it is important to be careful in dealing with capacitors. Large capacitors can even become destructive when they are shorted. Don’t forget to release a capacitor before heaving it away, as it may cause a fire.
