The use of twisted pair interconnects is recommended for all
installations to minimize noise. When routing these cables
through the automobile, try to keep them away from factory
wiring harnesses and other power wiring. If you need to cross
any of this wiring do so at a 90 degree angle to reduce the
potential of noise problems.
When working with power connections it is always
recommended that you disconnect the battery to prevent
accidents.
The ground should be connected to the amplifier first before
making any of the other connections. This wire should be as
short as possible (24 inches or less) and connected to a
paint/corrosion free solid metal area of the car’s chassis. Use the
same gauge wire as recommended for the amplifier’s power
connection to the battery. Adding an additional ground wire
between the car battery’s negative post and the car
chassis of this same gauge (or larger) is also
recommended.
If you ever need to remove the amp from the vehicle after it
has been installed, the ground wire should be the last wire
disconnected from the amplifier, just the opposite as when you
installed it.
A fuse must be installed within 18 inches of the battery to
protect the power wire feeding your amplifier. This fuse should be
of at least the same value used in the amplifier but no higher
than the capacity of the wire. See the chart below for wire size
and fusing recommendations.
RCA Dummy Plugs
When using both sets of High Level inputs, RCA dummy plugs
must be inserted into the AMP 2 inputs in order for the fader to
work properly. If the amplifier is being used in any other
configuration do not use the RCA dummy plugs! If you do not
have dummy plugs available, simply using raw RCA ends or
cutting the ends off of existing cables will be sufficient. See the
Amplifier Technical manual for more information. DO NOT USE
SHORTING PLUGS!
