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.
Displays the current voltage and/or other specification on an LCD readout.
This is the main color of the item.
A built-in distribution block simply means that the item includes a distribution block. The built-in distribution block will split the single power input into a multiple power output.
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.
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.

Car Audio Capacitors:

A car audio capacitor is an electrical circuit element used to store charge temporarily. This should not be confused with a battery, as a cap only temporarily holds a charge. It generally consists of two metallic plates separated by a dielectric. It is also used as a crossover component to filter out lower frequencies and allow higher frequencies to pass.

Audio capacitors charge and discharge very fast, stabilizing the voltage to the amplifier. Stabilizing the voltage helps the amplifier stay cooler and run more efficiently because the amplifier is not straining to get the power it needs. Stabilizing the voltage helps an amplifier reduce distortion and produce more power consistently.

A farad is the measurement unit used to determine the size of a capacitor. One farad to 500 watts RMS is the ratio used to determine the size of capacitor needed to supply enough power to an amplifier. While using a cap much larger than recommended will not damage an audio system, it is not recommended because of the unnecessary strain it puts on the vehicles electrical system.

Which Capacitor Should I Get?

Installing a capacitor is a great way to help stabilize the voltage being sent to the amplifier. This can help reduce the strain on the vehicle?s electrical system, reduce dimming lights, and improve sound quality of the audio system. Since each car is different and unique, knowing which capacitor is best for your system is important to know. As a general rule of thumb, Sonic Electronix uses the following information as a guideline for selecting capacitors:

Capacitor Farad RatingTotal System Wattage
Under 1 Farad0-499 Watts
1-1.9 Farad500-999 Watts
2-2.9 Farad1000-1499 Watts
3-4.9 Farad1500-2499 Watts
5+ Farad2500-Up Watts
