INSTALLATION PRECAUTIONS
Before you install the amplifier, invesgate your car's layout very carefully. Take special care
when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Before making
or breaking power connecons in your system, disconnect the vehicle baery. Confirm that
your head unit or other equipment is turned off while connecng the input jacks and speaker
terminals. If you need to replace the power fuse, replace it only with a fuse idencal to that
suggested by this manual. Using a fuse of a different type or rang may result in damage to your
audio system or your amplifier which is not covered by warranty .
CONNECTING THE AMPLIFIER

Use a nut and bol ! The ground cable must be at least the same size as the +12volt t
2. Connect the remote terminal to remote output of the head unit using 16 gauge upper wire.
3. Connect the fuse holder within 15”(30cm) of the car baery, and run the selected cable
from this fuse to the amplifier.
4. Connect all the inputs with high-quality cables. Connect Remote Control if necessary.
5. Insert fuse(s) into the baery fuse holder(s).
