Signal can be input into the amplifier using either the low level RCA input con-

nections or the high level (speaker level) connections. Using the low level RCA

connections is the preferred method. Use the high level inputs only if your head

unit does not have low level RCA type outputs.

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 dis-

connect 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 amplifiers 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 amplifi-

er, 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.
