INSTALLATION / MOUNTING

The Rockford Fosgate Reinforcement Capacitor should be mounted
as close to the amplifier as possible keeping the wire runs short to
reduce voltage losses in the cables. Use the mounting brackets
supplied to secure the capacitor as close to the amplifier as possible.

The capacitor may be mounted in any position; however, care should
be taken to ensure the venting hole on the top is unobstructed at all
times. This vent is a relief valve should the electrical polarity become
crossed. Should the capacitor be damaged, fluid will exit from this
vent rendering the capacitor useless.

Installation is simple and straightforward and should not be difficult.
When installing the capacitor, we recommend using the same gauge
wire as that of the power connection to the amplifier. Ground the
capacitor to the nearest chassis ground using the same gauge wire as
that used for the power connection. It is strongly recommended the
capacitor be fused at the battery. The fuse value should be the same
as that of the power connection to the amplifier. This fuse should be
installed 18" from the battery. (See illustration)

POWER WIRING CONSIDERATIONS

If the capacitor is to be used in a multi-amp system, a power
distribution block may be used between the capacitor and the
amplifiers. It should be wired using the same gauge wire as that of the
main system.

The positive side of the capacitor will be connected to the positive
side of the amplifier's power connection (B+).

CAUTION: Do Not overtighten screws. Stripped or broken terminals
are NOT covered by warranty.

CHARGING

The supplied resistor is used to initially charge the capacitors. The
charging process is accomplished by connecting the resistor in series
between the positive side of the battery and the positive terminal of the
capacitor. It is very important that polarity be observed and main­tained during this process to eliminate the possibility of damaging the
capacitor, the battery, or other associated equipment. Charging is
complete when the voltage at the capacitor reaches that of the
vehicle's battery. This process will take only a matter of seconds to
complete.

CHARGING VERIFICATION

A voltmeter should be used to verify that the capacitor is fully charged.
When the charging process is complete, the resistor may be discon­nected and stored for later use.

WARRANTY INFORMATION

Theses capacitors are nearly indestructible and will provide years of
service if installed and used in accordance with the instructions in this
manual. If this product should prove to be defective within a period
of ninety (90) days from the date of purchased, contact your dealer or
Rockford Corporation Customer Service Department at 1-800-669­9899 for replacement instructions.

In the event the vent is blown or leaking as a result of switched
polarity, the capacitor is not covered by warranty. Stripped screws or
terminals are not covered by warranty.

Power Indicator

When the LED is green,
the unit is on and func­tioning properly. If it is
red, immediately dis­connect the power and
check that positive and
negative are not hooked
up in reversed.

Positive Terminal

Connect to
vehicle's battery

Charge Level Indicator

With the engine running and
the system turned on at a
reasonable level, all bars
should be lit.

Negative Terminal

Connect to chassis
ground

Turn-on Wire

Attach amp turn-on
wire here to turn
electronics on and
off. (The cap is al­ways charged)

Sensitivity Adjustment

To set properly, turn engine on
and set system volume level to
an average listening level (90dB).
With a small screwdriver, turn
counterclockwise until at least 3
bars are not lit. Then, turn it
clockwise until all bars are lit
again. Be sure to stop as soon as
all bars are lit. This is the opti­mum charge level. If 5 or fewer
bars are lit during loud listening,
this is a good indication that you
may need more capacitance in
your system.
