in the power cable. Be sure to use fuses and a fuse holder adequate for the application
GND ( GROUND CONNECTION )
Locate a secure grounding connection as close to the amplifier as possible.
Make sure the location is clean and provides a direct electrical connection to the frame
of the vehicle. Connect one end of a short piece of the same size cable as the power cable
to the grounding point. Run one end of the cable to the grounding point.
Run the other end of the cable to the mounting location.
Connect the ground cable to the screw terminal labeled as GND.
REM ( REMOTE CONNECTION )
