Spec:Item Type: Car CapacitorMaterial: Metal, PlasticOperating Voltage: DC12VFeatures: 9.0 Farad, Reverse Connection GuardApplication: Supplementing current in case of unstable vehicle voltage, ensuring stable output of amplifierInstallation Method:1. For best results, the capacitor should be installed as close to the power amplifier as possible, using short power lines to connect. Install the capacitor in a place that is not easily accessible and to some extent isolates heat generated by the amplifier.2. Keep the power lines as short as possible and use a dedicated wire distribution seat to connect the battery circuit. Do not install the between the capacitor and power amplifier. Ensure appropriate are used to protect the power supply line on the battery's main supply cable.3. The negative connection of the capacitor should be as short as possible, directly connecting to the bare metal cable of the car chassis. Do not connect the negative terminal or negative wire of the power amplifier directly to the negative pole of the capacitor (see Fig.1).4. The power line of the capacitor should have the same GA number as the power line of the power amplifier, using high-performance 8 or 10AWG OFC wire is recommended.5. If the capacitor comes with a control line, use 18-20AWG main wire to connect the power amplifier's control line. Connect one end of the control line to the car sound's automatic antenna connector.Charging Process and Display Function Instructions:1. Connect the power line. First connect the negative, then connect the positive.2. During the first charging process, the digital display circuit system will automatically turn on. The status light automatically lights up and the decimal point of the voltage flashes, which indicates that the system is charging the capacitor.3. When the capacitor is fully charged, the decimal point display does not flash, and the digital tube displays the
