What Is A Capacitor?

A capacitor is a passive(meaning it consumes but does not produce energy) two terminal electrical component. In building a sound system for your car, you would want to use a capacitor for a couple of different reasons.

Why Do I Need One?

The main reason a capacitor is always recommended is for power reserve. The capacitor stores energy and releases it very quickly to the amplifier(s). This helps because music is dynamic, no matter what type you listen to. The dynamics in musical content can vary from soft voices to thundering bass notes. These moments are where the benefit of having a capacitor is heard. The amplifier requires a constant amount of steady power to function efficiently and power the speakers. A capacitor will keep the power going to the amplifier consistent and stabilized, which means a better sounding system. Important: The remote output of the head unit is connected to the remote turn on of the capacitor. The capacitor will not function if the remote wire is not connected to your head unit.


  • Three-digit, super bright blue LED voltage meter
  • Voltage measurement accurate to +/- 0.1VCD
  • Blue illuminated window
  • Warning tones for the following detected conditions: Reverse polarity connection, over voltage limit (above 17VCD), and low battery voltage (below 10VCD)


  • Capacitance, Microfarads – 10,000,000
  • Working voltage – 16VCD
  • Surge voltage – 20VCD
  • ESR (equivalent series resistance) – 0.0015 Ohm @ 120Hz/25ºC
  • Capacitance tolerance – +/- 10%
  • Dimensions – 10 - 5/6 x 9-1/7 x 3-5/8 (275 x 232 x 92)

Most Helpful Customer Reviews

Works as intended. Do not try and use the included resistor, mine started smoking because the pull of the capacitor is too high. I recommend an automotive head light you can watch a video of how to use it to charge the capacitor. I picked up a pack at advanced auto parts for like 4$. Overall I am satisfied with this purchase, I am using it to power a 1500 watt amp and I plan to add another 4000 watt amp. I liked the connection ports for the inputs and outputs. They are very large and comes with the Alan wrech tool for tightening. I like boss audio and recommend this capacitor if you are trying to keep your system powered. I went a little over kill with 20 farad but it's not dangerous. The rule of thumb I've seen is 1 farad= 1000w so purchase accordingly and good luck with your system.
Nice cap using it on 4000 boss phantom amp big difference in sound compared to a 4 farad cap sounds a lot clear then my 4 farad witch was the boss 4 farad chrome cap and these two are around the same price might as well get the bigger one quality is great.
my car never sounded so good. my amp was starving for current, despite huge + and - wiring.
