Once the capacitor is mounted, connect its positive terminal to the positive terminal of the battery using an 8-gauge wire. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. Yes. By using our site, you agree to our. Keep safety in mind when working with a charged capacitor. 0:13. They can get very hot, and if you have chosen too small of a resistor, they can blow up. It is also used as a crossover component to filter out lower frequencies and allow higher frequencies to pass. By putting it close to the parts that are not getting sufficient power you allow it to supply power to those parts with minimal loss do to the extra resistance of a long wire. Once the capacitor is charged the light will go out because current will no longer be flowing (the voltage drop between the power line and the capacitor will be zero). Setting up your audio system with two capacitors is honestly just as simple as installing one capacitor. Besides all the wires and the capacitor, you will need a voltmeter and a resistor (you most likely got one with the capacitor you purchased). For tips on how to charge a capacitor, read on! Many car audio fanatics will use a power capacitor as an alleged passive storage device to supply current to their amplifiers. First, you should go ahead and mount your audio capacitor. As for the positive wire, run the power wire from one audio capacitor to the other one then run a power wire connecting that audio capacitor to the amplifier and battery. Fosgate powered subwoofer - rockford fosgate slimline subwoofer. The best rockford fosgate subwoofers are P3D4-12 Punch P3 DVC 4-Ohm, R500X1D Prime 1-Channel,P3D4-10 Punch,R2S-1X10 Prime R2S Single,P3-2X12 1200 Watts . Wear safety glasses or goggles and remove any jewelry before installing the capacitor. http://www.caraudiohelp.com/car_audio_capacitors.html, http://www.crutchfield.com/S-QwuPR0qfqNW/learn/learningcenter/car/capacitors/faq.html#6, http://www.crutchfield.com/S-WEjsGucUkDY/learn/learningcenter/car/capacitors/faq.html, http://www.mobileaudio.com/rac-faq/rac-faq_2.html#SEC22, http://www.caraudiohelp.com/car_audio_capacitor_installation.html, http://www.popularmechanics.com/cars/how-to/a10359/installing-a-diy-car-amplifier-16639127/, consider supporting our work with a contribution to wikiHow, If you already have a capacitor in your system you will need to. Don’t forget to make sure you ground the negative terminal of the capacitor. This makes sure you will kill the power, letting you work without worry. Connect the positive terminal on the audio capacitor to the resistor. Now its finally time to install your car audio capacitor. Make sure everything has its own separate ground. Now all you need to do is get your voltmeter and connect it’s positive lead to the positive terminal of your capacitor. First things first, before you even install a car audio capacitor you will need to make sure you charge it so you don’t do something to your car like blowing a fuse.
