[. . . ] dO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND CONNECTIONS. Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc. Return it to your authorized Alpine dealer or the nearest Alpine Service Centre for repairing. [. . . ] Connect the ground lead securely to a bare metal spot (remove any paint or grease if necessary) of the car 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. Do not use the speaker (­) terminals as a common lead between the left and right channels. 2 RCA Input Jacks Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately). Be sure to observe correct channel connections; Left to Left and Right to Right. 5 Amplifier LINK Connector 6 Battery Lead (Yellow) (Sold Separately) Be sure to add a # 80 amp fuse (or four 20A fuses in parallel) as close as possible to the battery's positive (+) terminal. This fuse will protect your vehicle's electrical system in case of a short circuit. If you need to extend this lead, the wire gauge should be 8mm2 or larger. 7 Remote Turn-On Lead (Blue/White) (Sold Separately) Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit. 8 Ground Lead (Black) (Sold Separately) Connect this lead securely to a clean, bare metal spot on the vehicle's chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (­) terminal of the vehicle's battery. Ground all your audio components to the same point on the chassis to prevent ground loops. Cautions on wire lead connections When using third-party wire cables (power supply wire), use the supplied hex screws and the hex wrench (included) to simplify the connection. If you are in doubt about how to make this connection, consult your dealer. Wire Size (Battery Lead, Ground Lead) Recommended wire size for this unit is 21mm2 ­ 0. Remove the insulation from the ends of the wire leads by about 7 ­ 10mm (9/32" ­ 3/8"). If length of the exposed wire is too short, a poor connection may occur causing operation failure or sound interruption. On the other hand, if the length is too long, an electrical short-circuit may occur. Tighten the hexagon screw with the hex wrench (included), to fix the lead. 8) Before making this connection, use insulated shrink tubing to cover any exposed wire extending beyond the terminal. [. . . ] C) Setting this switch to "1 + 3/ 2 + 4" will sum the CH-1 and CH-3 input and send it to CH-3 while the CH-2 and CH-4 inputs are summed and sent to CH-4. When finished, close the top cover and secure with the original hexagon screws. When multiple amplifiers are connected to an Amplifier LINK compatible Head Unit, each amp must have its own, unique ID. Adjust the input level of the amplifier to match the output of the connected head unit. [. . . ]
