Capacitor Specifications

Capacitance (farads)
Capacitors are rated in farads, and at times microfarads or millionths of a farad. The more farads the capacitor is rated at, the more electrical charge (and wattage) the capacitor will hold. Capacitance is defined as the property of storing an electrical charge between two separate conductors.
3 farads
LCD Meter Display
Displays the current voltage and/or other specification on an LCD readout.
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Any Gauge with use of Ring Terminal AWG
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.
Any Gauge with use of Ring Terminal AWG

Why did you choose this?
Sonic Electronix Store
have used capacitors before, I had a 3 farad capacitor by spl, which is used for about 5 years before it was stolen, I have found a good capacitor eliminates all the things that can occur with high powered systems especially when the subs are called upon to workout and the amps are amplifying. I only know about these two brands of capacitors and they are a needed item for anyone needs extra supplementation to a auto stereo system. They work.

I picked this item because of the balance it had between price and out of the 20 reviews it had a majority of people said they had a good experience with the product.

What is the resistor for that comes with the capacitor?
A shopper on Feb 1, 2015
Best Answer: It allows you to charge and uncharge your capacitor which by the way works fine with my thousand watt amp you only need it during install and discharging when your done with it just put in line + side to charge then take back out when full charge opposite to discharge
