The remote turn on connection is located on the barrier strip next to the power and ground connections. This connection is responsible for turning the amplier on and off with the rest
of the system. A smaller gauge wire can be used to make this connection to your radio’s power antenna lead. Should your system not have any turn on leads, you can wire the remote
terminal to an accessory lead, which turns the amplier on with your car’s ignition.
The majority of the dB Series amplifers are supplied with built-in fuses. Never replace the built in or supplied external fuse with one of a larger value.
In order to protect the battery and electrical systems of your vehicle, construct a red wiring harness with a fuse and fuse holder located within 18˝ of the car battery. This fuse near the
battery offers protection against damage from short circuits to the car chassis between the battery and the amplier. This fused red power wire should be attached to the amplier power
terminal marked +12V. The wire harness should be made of red primary cable at least 8 gaug. The harness should terminate in a large ring terminal for connection directly to the positive
terminal of the car battery. An optional second fuse can be installed closer to the amplier for additional safety to the amplier itself.
A second black color wire of equal gauge should be used as a ground connection to a welded chassis member. When connecting the ground wire make sure that there is no paint or other
insulator blocking a good ground connection. When installing multiple ampliers, mount them in close proximity so that they can all share the same ground point. Attach the black ground
wire to the amplier screw terminal marked GND. Keep ground and power cables as short as possible.
We have received ampliers back to our service department with melted power/ground terminals. The cause of this is a bad ground connection. When there is a lack of good ground, heat
builds up at the weakest point which happens to be the contact screw of the amplier terminal. Over time the heat generated will begin to melt the terminal. It is a good practice to feel
the power and ground wires with your hands, near their amplier connection after having played the amp for a while. If the wires feel hot to the touch you probably have a bad or loose
connection. If you are sure of your connections and the wires still feel hot to the touch, you should upgrade the gauge of wire to next heaviest gauge.
Connections can work loose due to vehicle vibrations. We recommend tightening all power and ground connections in the system wiring as well as on the amplier terminals periodically,
at least once every 2 months.
