Sound Storm C352 3.5 Farad Car Capacitor for Energy Storage to Enhance Bass Demand from Audio System

View larger

A capacitor is a passive (a component that 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.


The main reason a capacitor is always recommend, is for power reserve. The capacitor stores energy and releases it very quickly to the amplifier(s). How does this help? It’s very simple: Music is dynamic, no matter what type you listen to. The dynamics in musical content can vary from soft voices, and very quickly transition 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.

Charging The Capacitor

First make sure that all the connections according to the diagrams in the instruction manual are correct. Pick up the cable coming from the POSITIVE (+) battery terminal. Place the supplied charging resistor between the end of this cable and the positive terminal of the capacitor. The capacitor will begin charging. Charging generally takes 5 to 60 seconds. During charging, the voltage shown in the 3 digit display will rise rapidly, then slow as it approaches the voltage of your vehicle’s battery. When fully charged, the display voltage will stop rising. If you have a voltmeter, you can first measure the voltage of your car battery. Then you will know with accuracy that the capacitor is fully charged. CAUTION!! During charging, the resistor will become hot. This is normal, but exercise caution during the charging process. After charging is complete, remove the resistor from the incoming positive cable, and IMEDIATELY connect it to the positive terminal of the capacitor.

    Buy ten of these. This capacitor works as I expected. I’m not about to even consider seeing my lights flickering, even without a capacitor. I bought a second one of these caps because I’m about to add a third SSL 4000 Watt Class D Monoblock amp, and already have a 1600 watt Class A/B 4 Channel for my Infinity’s. This cap simply bumps the amperage when the song bumps…sending the signal to the amp and then draining your amp draw…so it only makes sense to give the system some oomph when it’s needed to make up…
