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 amplier 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 amplier 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.



We suggest you construct a red wiring harness with 2 additional fuses. One fuse should be located near the car battery. This fuse near the battery offers protection against damage

from short circuits to the car chassis between the battery and the amplier. A second fuse closer to the amplier offers additional safety to the amplier itself. This fused red power wire

should be attached to the amplier power terminal marked +12V. The wire harness should be made of red primary cable of at least 8 gauge for the dB12 and at least 4 gauge for all

other larger models. The harness should terminate in a large ring terminal for connection directly to the positive terminal of the car battery.

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 ampliers, mount them in close proximity so that they can all share the same ground point. Attach the black

ground wire to the amplier screw terminal marked GND. Keep ground and power cables as short as possible.

We have received ampliers 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 amplier 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 amplier 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 amplier terminals periodically,

at least once every 2 months.
