Our take on the StreetWires ZeroNoise1 Capacitor

by Buck Pomerantz

If your car's sound system needs a little help on the beat because you're straining your electrical system, then a StreetWires ZeroNoise1 ZN1-1FC capacitor may be just what you need. This 1-farad cap can smooth out the power demand peaks for systems up to 1,000 watts RMS, so the lights won't dim every time your sub hits hard. The ZN1-1FC is rated at 16 volts max (20 volts surge), so it'll handle almost any electrical surge your system may experience, even during peak demand.

Features

Overview: The StreetWires 1 Farad/20 VDC Capacitor (ZN1-1FC) maintains consistent voltage to your car audio system. When you turn up the volume on your audio system you strain your vehicle's electrical system, 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 ZN1-1FC Capacitor helps prevent this and keeps your headlights from dimming when your bass hits. The 1 Farad 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 delivers large quantities of current in a short time, which results in improved system performance.

Mounting: In order for the capacitor to deliver the maximum possible benefit it should be located as close to the amplifier as possible. The package includes a pair of plastic 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 is recommended for installing the 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 0.25" in diameter.

Charging Capacitor: The capacitor includes a resistor for initial charging. 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 the 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 reads 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.
