3.2 - Route the low-level audio cables (RCA cable), the loudspeaker cables, the POWER REMOTE cable,
ensuring to isolate them from powerful automobile accessories, particularly electric motors (windshield
wiper,...). Keep the whole length of the cables, which will be adjusted later on.
3.3 - Route the positive power cables (+). Make sure when doing so to route them opposite the cables that you
have previously drawn – this is to avoid any interference. DO NOT CONNECT THE CABLE YET.
3.4 - 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 effective coupling between the amplifier and the car's chassis. The cable
and its wire gauge should comply with the table on page 7. Find a suitable ground point
to remove any traces of paint or other covering and in so doing optimise the contact point. Pierce the metal
that you have previously sanded, making a hole the same size as the screw you are using, making sure that
there are no tank cables or any other sensitive vehicle devices nearby. Remove the plastic around 1 cm of cable
and then tin it. Screw the cable firmly down onto the amplifier's GND terminal. Tin the other end of it and then
crimp or weld it onto the terminal lug provided. Insert the terminal lug in the screw, and then put the screw and
nut in place and screw-drive the screw in firmly.
