Connections
1
GROUND (-)
Ground connection should be made to the vehicle’s chassis with a clean, bare metal, strong connec-
tion keep the length of the ground wires as short as possible. Always use the same wire thickness as used for the
positive 12V DC connection.
2
REMOTE INPUT (REM)
This is the connection to turn the amplifier on and off. When a +12V DC voltage is applied
to this terminal the amplifier will switch on, when this voltage is removed the amplifier will switch off. Usually this
is done by the source unit’s remote output. The source unit’s remote output lead or power antenna lead will supply
+12V DC when the unit is turned on.
3
POSITIVE (+12V)
Positive power connection should be made directly to the vehicle’s battery positive (“+”) ter-
minal. Use the proper wire thickness (see Power Wiring Connection chart) and make sure you install an inline
fuseholder within 18 inches of the battery connection, the fuse rating for each EFX amplifier is given in the speci-
fications.
