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.
