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 to 8 gauge power wire for your connections depending on the amplifier and length of the wire. Strip one end of the wire and crimp on a barrier spade connect to the terminal on the amplifier marked “+12V”. Loosen screw terminal and connect barrier spade and tighten (QS1500D uses bare wire connection). Use caution to make sure no stray wire stands 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
Connect the ground terminal of the amplifier to the car's chassis.
For the ground connection, use a 4 to 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". Also 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.
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. This connection can also be made to the radio’s Power Antenna wire.
