Connection Diagram of SPST Switch (sold separately)
(If the ACC power supply is not available)
• If your vehicle has no ACC power supply, add an SPST (Single-Pole, Single-Throw) switch (sold separately) and fuse (sold separately).
• The diagram and the fuse amperage shown above are in the case when X008U/INE-W957HD is used individually.
• If the switched power (ignition) lead of the X008U/INE-W957HD is connected directly to the positive (+) post of the vehicle’s battery, the
X008U/INE-W957HD draws some current (several hundred milliamperes) even when its switch is placed in the OFF position, and the battery may
be discharged.

To prevent external noise from entering the audio system.
• Locate the unit and route the leads at least 10 cm 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, dirt 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.
