3.3.2 – Get the negative power cable (-). This cable should be as short as possible and ideally shouldn't be any longer
than 3ft (1m), 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 suitable grounding point, then sand it to remove any traces
of paint or other coating in order to optimise 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. Solder the ground cable to the wiring harness supplied for
your IMPULSE 4.320 amplifier and isolate using heat-shrink tubing (fig. 2).

Connect the RCAs to the RCA adapter cable supplied (fig. 3). Be careful to respect the polarities (INPUT Left = red, INPUT
Right = black or white) and distribution (F=FRONT, R=REAR). Connect the other end to the amplifier's INPUTS panel.
