Our take on the StreetWires Power Station PSC401D

The StreetWires PSC401D 1-farad capacitor is rated at 20/24 volts, and the digital display lets you see immediately how much power you're drawing. It installs in-line between your battery and amplifier, delivering the extra power you your amp needs to maintain consistent voltage during peak demand. Use ring terminals to mount any gauge cable to the machined brass Diamond Nickel-plate mounting studs. The clear, polycarbonate terminal cover protects your connections, and included brackets let you mount your cap securely.

Product Research


Overview: The StreetWires Power Station Digital Capacitor (1 Farad, 20/24 Volt) maintains consistent voltage to your audio system. When your turn up the volume on your audio system, you put more strain on your vehicle's electrical system and even more so during severe transient peaks and heavy bass loads. The result is a voltage drain on your electrical system with decreased output from your audio system and other vehicle electronics. Adding the Power Station Digital Capacitor helps prevent this and keeps your headlights from dimming when your bass hits. The capacitor increases the performance of your car audio system by reducing the voltage changes in your power delivery system caused by large loads, in doing so it delivery large quantities f power in a very short amount of time which will result in increased system performance.

Digital Display: The PSC401D features a Digital Voltage Display and also offers current sensing activation and shut down, as well as audible warnings.

Mounting: In order for the digital capacitor to deliver the maximum possible performance it should be located as close to the amplifier as possible. The digital capacitor comes supplied with a pair of metal mounting brackets and four self-tapping screws to firmly secure the capacitor to a metal or wood surface in your vehicle.

Connections: The use of 4 gauge cable for the positive and negative connections are recommended for installing the digital capacitor. The length of the cables should be kept as short as possible and the wire connectors should be fastened securely under the capacitor terminal studs. The capacitor's terminal studs measure 0.275" in diameter.

Charging Capacitor: The digital capacitor comes supplied with a resistor for initial charging for the device. Remove the negative cable from your vehicle and system batteries and install the included resistor in place of the main power fuse. Connect all power cables to the appropriate battery terminals and wait approximately 10 minutes for the capacitor to fully charge. Once charged, the resistor may be removed from the fuse holder and the main fuse reinstalled.

Note: Use caution when touching the resistor as it will have heated up while charging.

Discharging Capacitor: The resistor should be kept to discharge the capacitor if removed from system. Remove the negative cable from the vehicle and system batteries. Then place the resistor between the positive and negative terminals of the capacitor. Quickly do so and release the resistor, as it will become hot while discharging the capacitor. Wait approximately 10 minutes for the capacitor to discharge and check with a digital voltmeter to make sure the voltage is at a nominal level (less than 1 volt). It is now safe to remove the capacitor from the vehicle.

Note: It is a good idea to leave the resistor installed on the capacitor while not in use.
