Add an external fuse with the same capacity, or a slightly larger capacity, as the sum total of the fuse capacities of the amplifier. For details on the fuse capacity of this machine, see "Battery Lead ( )" (page 5). *3 Connect all equipment to the same ground point while keeping wire length as short as possible. *4 To securely connect the ground lead, use an already installed screw. To prevent external noise from entering the audio system • Locate the unit and route the leads at least 10 cm (4") away from the vehicle's harness. • Keep the battery power leads as far away from other leads as possible. • Connect the ground lead securely to a bare metal spot (remove any paint or grease if necessary) of the vehicle's chassis. • If you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries various noise suppressors, contact them for further information. • Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information.
