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.
LCD Meter Display
Displays the current voltage and/or other specification on an LCD readout.
Primary Color
This is the main color of the item.
Built-In Distribution Block
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.
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.
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.

    FAQ Frequently asked questions in Discontinued Audio Capacitors

    Car Audio Capacitor Frequently Asked Questions (FAQ)
    A car audio capacitor is an electronic component that stores and releases electrical energy to support high-demand audio systems. When amplifiers require a surge of power to deliver heavy bass hits or loud music passages, the electrical system might experience voltage drops. Capacitors act as a buffer, providing instant power when needed, reducing strain on the alternator, and preventing dimming headlights or other electrical issues. High-power audio systems can benefit from capacitors by ensuring a stable voltage supply, resulting in improved amplifier performance and cleaner sound output.
    If you have a high-power audio system with large amplifiers, subwoofers, and upgraded speakers, you may experience voltage drops and dimming lights when playing music at high volumes. These are indications of a strained electrical system. Installing a car audio capacitor can alleviate these issues by providing the extra power needed during peak demands, improving amplifier performance, and maintaining consistent voltage levels. If you notice any signs of electrical strain or audible distortion at high volumes, adding a capacitor to your system may be beneficial.
    The size and capacity of the capacitor you need depend on your audio system's power requirements. Capacitors are measured in Farads (F), and higher capacity capacitors can store more electrical energy. To determine the right size, calculate the total RMS power output of your amplifiers. As a general rule of thumb, a 1 Farad capacitor is suitable for every 1,000 watts RMS of total amplifier power. For example, if you have 2,000 watts RMS of amplifier power, a 2 Farad capacitor should be sufficient. However, it is essential to consult with a car audio expert or use Sonic Electronix's AmpliFinder tool to ensure you select the appropriate capacitor size for your specific setup.
    Installing a car audio capacitor involves several steps. First, disconnect the vehicle's negative battery terminal to ensure safety. Next, identify a suitable location near the amplifier(s) to mount the capacitor. Install the capacitor by connecting the positive power wire from the amplifier(s) to the positive terminal of the capacitor and the negative terminal to a suitable ground point. It's crucial to use proper wire gauge and secure connections to prevent voltage drops and potential hazards. After the installation, reconnect the battery terminal and test your audio system. If you are unsure about the installation process, it's best to seek assistance from a professional car audio installer to ensure a safe and reliable installation.
    While car audio capacitors can improve voltage stability and prevent voltage drops, they may not fix all power-related issues. If your audio system experiences significant voltage drops, dimming lights, or audible distortion at high volumes, adding a capacitor can help alleviate these problems. However, if the electrical demands of your audio system exceed the capabilities of your vehicle's stock alternator or battery, a capacitor may not be a complete solution. In such cases, you may need to upgrade your alternator or battery to handle the increased power demands. It's essential to assess your audio system's power requirements and consult with a car audio expert to determine the most effective solution for your specific setup. Sonic Electronix's expert staff can assist you in selecting the right capacitor and providing guidance on any additional upgrades needed to optimize your car audio system's performance. Car audio capacitors are valuable accessories for high-power audio systems, providing the extra power needed during peak demands and ensuring a stable voltage supply. By understanding your audio system's power requirements and selecting the appropriate capacitor size, you can enhance your car audio experience and enjoy clean, distortion-free sound at any volume level. Sonic Electronix offers a wide selection of high-quality car audio capacitors from top brands, ensuring you find the perfect capacitor to meet your system's needs.
