Input Connections
This amplifier will accept low level inputs. Low level is the same as line level or preempt level.
Low level signal is carried through RCA cables. It is preferred to use low level inputs to the amplifier if
the head unit is equipped with the low level outputs.
Low level/line input-connect RCA cables from head unit, or other signal processor, to the line level
input on the amplifier. See Fig.2 system wiring diagrams.
Power Connections
It is important to have good quality power and ground connections. Remember, to complete an
electrical circuit, the ground connection is just as important as the positive power connection. Before
any power connections are made, disconnect the ground cable at the battery.
2 When the power supply lead. Memory backup lead or ground lead are extended, use a 5mm (AWG5)
or larger automotive grade cable which will withstand friction and heat to safe guard against fires
occurring as a result of short-circuiting.
Ground-Connect the proper gauge ground wire to the amplifier "GND" terminal. Locate the position
on the chassis of the car to which the amplifier is to be ground. The surface must be free from any
paint or dir. This can be accomplished with a small grinding bit or wire wheel. NOTE: Do not ground
amplifier to the "frame" of the car, the frame on most cars and trucks is not grounded to the chassis
(body). Solder or clamp ring terminal to ground wire. Pretrial the prepped chassis metal to bolt the
ground ring terminal with nut, bolt and lock washers. Insulate mental and connector with paint or
silicon to prevent rust and oxidation. Silicon also works great to prevent nuts and bolts from working
loose in a harsh environment of an automobile. Upon completion of ground connection, grab wire or
connector and confirm that it is a solid connection. To prevent engine noise, it is recommended to
ground the head unit and other audio electronics in the same location.
Remote Turn-on-Connect smaller light gauge wire to "REMOTE" terminal of amplifier and to remote/
antenna turn-on output or "remote amplifier" of head unit. If head unit is not equipped with a remote/
antenna output, locate a wire that is controlled by the accessory position of the key. It is important to
have the amplifier turn off with the radio or key. If the amplifier remains on, the result will most likely
be a dead battery.
Positive-Connect the proper size wire to the amplifier "B+" terminal of amplifier. Run wire to wards the
fuse holder that is no greater then 0.5 meters from the battery. Remember, the fuse is to protect the
safety of the car in the case of a short. Connect fuse holder to battery, however, do not install fuse at
this time.
