For Optimum Performance: Position the Power Cap no more than 36 inches from amplifier.

Determine the desired location within
your vehicle as close to your audio
amplifier as possible. Attach mounting
brackets to the capacitor.
Make sure lower bracket is around the
bottom of the capacitor, and that the
capacitor is supported by the lip on
the bottom of the lower bracket. The

Hold capacitor in place and mark the
holes as shown. See Fig. 1

With a hammer and center punch,
dimple the marks, to prevent the drill
bit from slipping.

Using an electric drill with a 1/16"
high-speed bit, drill the pilot holes
where dimpled with the center punch
for the mounting brackets.

Mount both bases of the brackets,
position the Power Cap inside the
mounting brackets, make sure the
bottom of the capacitor is supported.
Position the retaining brackets over
the Power Cap. Line up the screw
holes on all pieces. Insert and hand
tighten the provided screws with a
philips screwdriver to mount the
Power Cap firmly in place. See Fig. 2

Wiring Overview

Strip a fingernail width of insulation from
the chassis ground wire and twist the
ends together. Insert the negative (-)
chassis ground wire into a lug, tighten
the set screw. Fig. 3

Take the remaining lug and insert the
end of the supplied cartridge light bulb,
and gently tighten the set screw. Fig. 4

Connect both lugs to the terminal
posts of the capacitor with the terminal
post screws. Make sure to maintain
polarity by connecting the chassis
ground lug to the negative terminal,
and the lug with the light bulb with clip
to the positive terminal. Fig. 5

Open the jaws of the clip and take the
positive wire from the battery and insert
it into the clip, let the jaws of the clip
close on the end of the wire. The bulb
will light brightly at first, and as become
dim as charging occurs. After about
twenty seconds, the blue LEDs and the
numbers on the digital voltage display
will light, and you will hear a beeping
sound. When the cartridge light goes out
the capacitor is charged. With the
positive lug still attached, remove the
light bulb. Fig. 6

Insert the positive wire from the amplifier,
and the positive wire from the battery,
into the positive lug and tighten the set
screw. Fig. 7

Connect the positive lug to the positive
terminal of the capacitor, secure the lug
tightly with the positive terminal post
screws. Fig. 8

Be advised that the digital voltage
display on the VRPC1000 power
capacitor will automatically turn OFF
after two minutes of operation at a stable
voltage. It will also turn back ON
whenever a change of more than 1.5
Volts occurs. It is normal for the digital
