When it comes to installing a car audio ultracapacitor, you have a couple of options. You can use a standard electrolytic capacitor or a carbon car capacitor. The difference between the two is the type of materials used to create them. For example, carbon car capacitors are larger but won’t recharge as quickly as electrolytic ones. They may be larger, but they also require a battery and may use the same amount of farads. However, if you want to use a hybrid car ultracapacitor, you can use it as a second battery in your vehicle.
Another choice is the Planet Audio cap. This cap comes with extras for your car stereo. It has a ten million uF capacitance and a 16-volt power output. Because it can power up to 24VDC, it can keep your headlights bright even when you play music at a high volume. Depending on the type of car audio ultracapacitor you choose, you may want to consider the extra features it offers.
If you’re considering adding a car audio system to your vehicle, you’ll probably want to over-build the electrical system to handle the peak power demands of the speakers. However, don’t forget that power is the same as resistance times squared. A ten kW car audio system will use as much as 100 amperes of current at its peak. So, you don’t want to run into this problem.
