3.3.2 – Get hold of the negative power cable (-). This cable should be as short as possible and ideally
should not be any longer than 1 metre, to ensure a perfect connection between the amplifier and the
chassis of the vehicle. The cable and wire gauge must comply with the table in section 3.1. Find a sui-
table grounding point, then sand it to remove any traces of paint or other coating to maximising the
quality of the contact point. Drill a hole in the metal that you have previously sanded, making a hole
the same diameter as the screw you are using, making sure that there are no fuel lines, cables or any
other sensitive vehicle devices nearby. Crimp the black Y-type spade terminal supplied to the end of
the cable. Screw the black Y-type spade terminal firmly to the GND terminal on your FDS amplifier (fig.
2). Tin the other end of the cable and then crimp or solder it onto the intended spade terminal. Insert
the screw through the spade terminal, then put the screw and the nut in place and screw tight. (fig. 2)

3.4 – Connecting the input signals to your FDS amplifier
You can now start the connection phase of the input/output cables.
3.4.1 – Your head unit is equipped with RCA outputs (fig. 3)
Connect the RCA cables to the amplifier. Be careful to respect the polarities (INPUT Left = black or
white, INPUT Right = red). Then connect the other end of the RCA cable(s) to the appropriate RCA*
outputs of the head unit (Left and Right).
Now connect the REMOTE cable to the amplifier (REM terminal) and screw tight. Connect the other
end of the REMOTE cable to the REMOTE terminal on the head unit. Finally, connect the speaker driver
cables to the amplifier. Be careful to respect the polarities (+ with + ; - with -) by using the red and black
Y-type spade terminals supplied.
