IMPORTANT! Before making any connections, disconnect the car's battery until
the installation is completed to avoid possible damage to the electrical system.
Connect the amplifier to the car's battery.
At times, the amplifier will need to draw large levels of current that cannot be provided by
any circuit in the car's fuse box. We recommend using a 4 or 8 gauge power wire for
your connections depending on the amplifier and length of the wire. Strip one end of the
wire and connect to the terminal on the amplifier marked "+12V". Loosen the set screw
on the terminal and insert wire and tighten. Use caution to make sure no stray wire
strands come in contact with surrounding terminals causing short circuits. Run the wire
directly to the positive terminal of the car's battery. Make sure to use an in-line fuse
within 6" of the car's battery to protect the electrical system and amplifier against short
circuits and/or power surges.
Connect the ground terminal of the amplifier to the car's chassis.
For the ground connection, use a 4 or 8 gauge wire (black) to connect to the terminal
marked "GND" and then connect it to the car's chassis. Try to keep the length of the
cable as short as possible, preferably less than 6". Make sure that the point on the car
where the connection is to be made is free of paint and dirt.
Connect the remote terminal of the amplifier to a switchable +12V source
Please note: If you intend to use the high level inputs for your signal connections, we
provide a "Remote Auto Sensing" feature that will automatically turn-on the amplifier
when the high level inputs sense input signal. Please skip this step and see page 12.
This connection allows the amplifier to be turned on and off with the power control of the
radio. If the radio has a REMOTE output terminal, connect it to the amplifier's terminal
marked "REM" (using a 16 gauge wire or heavier). Now when the radio is turned on, the
amplifier will automatically turn on. When using this wire, the "REMOTE AUTO
SENSING" switch should be in the "OFF" position.
