Fasten the unit down with the four self-tapping screws (M4 x 40, supplied). NOTE: A magnetic screwdriver is recommended to prevent the screw being dropped while tightening. Attach the four joint caps (supplied with connected amplifier) in the four corners of the first unit with 2 machine screws (M2. 6 x 14, supplied with connected amplifier) per each cap.

Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle's battery. Do not connect this lead to the fuse block. cAUTION Caution on connection terminals/parts · Do not allow other objects (particularly electrically conductive) to get too close or in contact with any of the unit's terminals/parts (power supply, fuse, speaker output terminal, RCA connector, etc. Doing so may result in short circuit or accident. Locate the unit and route the leads at least 10 cm (3-15/16") away from the car 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 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. 1 Power Supply Terminal 2 Fuse 3 Speaker Output Terminals Referring to "Cautions on speaker wire connections", insert the speaker wire into the speaker plug, which is then inserted in the speaker output terminal. note: · Fully insert the speaker plug to avoid poor connection, or the wire coming loose due to vehicle vibration, etc. [. . . ] If in doubt, consult your dealer regarding correct wire gauge to use.
