Power Connections
It is crucial 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 of the battery. Use 8 gauge or larger automotive grade wire if the distance from the battery to the amp is
excessive. Avoid sharp or rough edges as a safeguard against short-circuiting and potential fire hazards.
GND = Connect the proper gauge ground wire to the amplifier GND terminal. Locate the position on the chassis of the car
where the amplifier will be grounded. Use solder or a crimped ring terminal to connect the ground wire. Pre-drill the
prepped chassis to bolt the ground ring terminal with a nut, bolt, and lock washer. Insulate the metal and the connector
with paint or silicone to prevent rust and oxidation. Silicone also works great to prevent nuts and bolts from working
loose in harsh environments of an automobile. Upon completion of the ground connection, grab the wire and connector
to confirm the connection is solid. To prevent engine noise, it is recommended to ground the head unit and other
electronic audio devices to the exact location.
REM = Connect the remote wire (power antenna output) from the head unit to the REM terminal. If the head unit is not
equipped with a remote/antenna output, locate a wire controlled by the key's accessory position. It is crucial to have the
amplifier turn off with the radio or key. If the amplifier remains on, the battery will drain.
12V = Connect the proper gauge power wire to the B+ terminal. Trace the power wire through the car to the in-line
fuse or circuit breaker that is no more than 18" from the battery. Remember, the in-line fuse or circuit breaker
protects the vehicle in the event of short circuit. Connect the in-line fuse or circuit breaker to the battery, but do not
install the fuse or activate the circuit breaker yet.
