Preparation
This connection turns on the amplifier
when you turn on the auto sound sys-
tem, and turns off the amplifier when
you turn off the auto sound system. This
prevents your vehicle’s battery from
being drained if you leave your amplifier
on when you turn off your auto sound
system.
If your auto sound system does not have
a switched power lead
, connect the
blue/white wire’s other end to a point in
your vehicle’s fuse block that has power
only when you turn on the ignition or turn
the key to ACC.
This connection turns on the amplifier
when you turn on the ignition or turn the
key to ACC, and turns off the amplifier
when you turn off the ignition. This pre-
vents your vehicle’s battery from being
drained if you leave your amplifier on
when you turn off the ignition.
6. Use a screwdriver to connect the spade
end of the supplied red power cable
(with in-line fuse holder) to the ampli-
fier’s
+ 12V
terminal.
7. Connect the other end of the red power
cable to your vehicle’s positive (+) bat-
tery terminal. Then tighten the terminal.
Caution:
Due to the amplifier’s high cur-
rent requirement, you must connect the
red power cable’s fused end directly to
the vehicle’s positive (+) battery terminal
or damage to your vehicle’s wiring could
result.
Do not reconnect your vehicle’s negative (–)
battery cable yet.
