5. CAUTION Avoid running power wires near the low level input cables antenna power leads sensitive equipment or harnesses The power wires carry substantial currentand could induce noise into the audio system For safety disconnect the negative lead from the battery prior to beginning the installation 1 Plan the wire routing Take care when running signal level RCA cablesto keep them close together butisolated from the amplifier s power cables and any high power auto accessories especially electric motors This is done to prevent coupling the noise from radiated electrical fields into the audio signal W hen feeding the wires through the firewall or any metal barrier protect them with plastic or rubber grommets to prevent short circuits Leave the wires long at this point to adjust for a precise fit at a later time 2 Prepare the Power cable for attachment to the amplifier by stripping 5 8 of insulation from the end of the wire The use of 8 gauge power cable can interfere with the installation of the end caps Proper wire dress can prevent this from occurring To prevent the wire from fraying strip the insulation at a 45 angle Insert the bared wire into the B terminal with the long side of the insulation on the top Bend the cable down ata 90 angle Tighten the set screw to secure the cable in place 10 3 Punch 160xX4 Trim the power cable to within 18 of the battery and install the protective rubber boot packed with
