1. Make sure to disconnect the NEGATIVE (-) terminal from your car’s battery.
2. Attach an 8 guage or heavier wire to the amplier screw terminal marked GND. Connect the other end to the car’s chassis. The connection should be as close to the amp as possible;
preferably 40˝ or less. 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.
3. Connect the remote terminal to the head unit’s remote output using 16 gauge or heavier wire. This connection is responsible for turning the amplier on and off with the rest of the
system. If there is no dedicated remote output, make this connection to the power antenna lead. Should your head unit 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.
4. Use 8 gauge or heavier wire to connect the screw terminal marked +12V to the car battery’s POSITIVE (+) terminal. In order to protect the battery and electrical systems of your
vehicle, add an in-line fuse holder within 18˝ of the car battery. This in-line fuse offers protection against damage from short circuits. The power wire should terminate in a large ring
terminal connected directly to the POSITIVE (+) terminal. An optional second fuse can be installed closer to the amplier for additional protection to the amplier itself. If installing multiple
ampliers, install a distribution block near their location and, using a 4 gauge wire, connect the block to the in-line holder that is connected to the battery.
5. Insert fuse(s) into the in-line fuse holder(s) and check that all connections are properly secured.
6. Before powering up the system, set all of the amplier’s level controls to minimum, the crossover/setting switches to the desired postion, and the head unit’s volume to 3/4.
We have received ampliers back to our service department with melted power/ground terminals caused by a bad ground connection. When there is a lack of good ground, heat builds up
at the contact screws 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 near the amplier after
using the amp for a while. If the wires feel hot to the touch you probably have a bad or loose connection. If after adjusting your connections the wires still feel hot, you should upgrade to
next heaviest gauge wire. As connections can work loose due to vehicle vibrations we recommend periodically tightening all power and ground connections.
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.
