The QRS Series amplifiers are supplied with built-in fuses, never replace the fuse that the amp came with, 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 amplifier. A second fuse closer to the amplifier offers additional safety to the amplifier itself. This fused red power
wire should be attached to the amplifier power terminal marked
12V+
.
The wire harness should be made of red primary cable of at least 4 gauge for all QRS Series amplifiers. The harness should terminate in a large ring terminal for connection directly
to the positive terminal of the car battery. Use a spade plug to attach the wire, which connects to the amplifier location marked
12V+
.
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 amplifiers, mount them in close proximity so that they can all share the same ground point. Attach
the black ground wire to the amplifier screw terminal marked
Ground
.
We recommend that you use the Cadence AMPKIT4 or AMPKIT8 amplifier installation kits, which contains all the cabling and accessories necessary for a good, reliable installation.
Over the years we have received amplifiers 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 amplifier 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 amplifier 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.
