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.
When the power supply lead, memory backup lead or ground lead are extended use a 5mm
friction and heat to safe grade against fires occurring as a result of short-circuiting.
GND = 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
grounded. The surface must be free from any paint or dirt. This can be accomplished with a small grinding bit, sand paper or wire wheel. NOTE: Do not ground
the amplifier to the "frame of the car. The frame on most cars and trucks is not grounded to the chassis(body). Use Solder or a clamp ring to connect the ground
wire. Pre-drill the prepped chassis to bolt the ground ring terminal with nut, bolt and lock washers. Insulate metal 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 the
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.
REM = Connect the remote wire (power antenna output) from the head unit to the remote turn-on wire of the amplifier. If the 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.
12V = Connect the proper gauge power wire to the amplifier "B+" terminal. 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, but do not install fuse at this time.
