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.
Thecapacitormaybemountedinanyposition;however,careshould
be taken to ensure the venting hole on the top is unobstructed at all
times.Thisventisareliefvalveshouldtheelectricalpolaritybecome
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.Itshouldbewiredusingthesamegaugewireasthatofthe
main system.
The positive side of the capacitor will be connected to the positive
side of the amplifier's power connection (B+).

CHARGING
The supplied resistor is used to initially charge the capacitors. The
chargingprocessisaccomplishedby connecting the resistor in series
betweenthepositivesideofthebatteryandthepositiveterminalofthe
capacitor. It is very important that polarity be observed and main-
tainedduringthisprocesstoeliminatethepossibilityofdamagingthe
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
Avoltmetershouldbeusedtoverifythatthecapacitorisfullycharged.
When the charging process is complete, the resistor may be discon-
nected and stored for later use.

Power Indicator
Whenthe LED is green,
the unit is on and func-
tioning properly. If it is
red, immediately dis-
connect the power and
check that positive and
negativearenothooked
up in reversed.
Positive Terminal
Connect to
vehicle's battery
Charge Level Indicator
Withtheenginerunningand
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 al-
ways charged)
Sensitivity Adjustment
To set properly, turn engine on
and set system volume level to
anaveragelisteninglevel(90dB).
With a small screwdriver, turn
counterclockwiseuntilatleast3
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 opti-
mum charge level. If 5 or fewer
barsarelitduringloudlistening,
thisisagoodindicationthatyou
may need more capacitance in
your system.
