SAEv4 SERIES AMPLIFIER OWNER’S MANUAL version 1.1
+12V Battery
You need to connect a power wire to the vehicle’s positive battery terminal. This connection must be tight and
secure to ensure proper connectivity. This wire must be fused appropriately (see each amplifier’s fuse rating
under specifications) within 12 to 16 inches for safety. You will then need to connect the power wire to the 12+
terminal of the amplifier with a Phillips screwdriver. Do not install the fuses until installation is complete.
Ground Connection
It is recommended that you connect your ground directly to your power source ground for the best possible
performance. However, if you cannot, then the ground connection must be made to the vehicle’s chassis and
should be kept as short as possible, while accessing a solid piece of sheet metal in the vehicle. The surface
should be sanded at the contact point to clean rust, paint or grime so a metal-to-metal connection between the
chassis and the termination of the ground wire is effective. You will then need to connect the ground wire to the
GND terminal of the amplifier with a Phillips screwdriver.
Remote
The +12V remote turn-on wire is typically controlled by the source unit’s remote turn-on output. The amplifier will
turn on when +12V is present at its remote(REM) input and turn off when +12V is switched off. Connect the
remote wire using 12 to 16-gauge wire to the REM connection of the amplifier with Phillips screwdriver, then
connect the other end of the remote wire to either the source unit’s turn on output or ignition switch circuit. The
models that have the extra power input will have an extra REM connection noted as OUT, this is intended to
allow you to connect your REM line to other devices if needed.
