Wiring
Signal can be input into the amplifier using either the low level
RCA input connections 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. Connecting to the
amp with either input will provide a low level signal at the output
(PAST) jacks.

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
possibility for 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 (36 inches or less) and connected to a paint
and 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 highly recommended. Adding or
upgrading the ground from the case of the alternator to the car
chassis 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.
The supplied ANL fuse holder and fuse must be installed within
18 inches of the battery to protect the power wire feeding your
amplifier.
The Remote Turn-On lead gets connected to your source unit’s
power antenna lead or another switched + 12 volt source in your
vehicle.
