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
2
(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.
