ELECTRICAL INSTALLATION
Wiring Precautions
• Improper wiring connections can seriously damage amplifiers, accessories, or speakers. Be sure to carefully follow the
connection instrurtions in this manual. If you are not sure of the connections, contact your dealer.
• Disconnect the positive (+) lead at the battery before making any power connections.
• Be sure to connect the amplifier's positive (+) power lead directly to the positive (+> terminal on the battery. Do not con¬
nect this wire to the car's fuse panel. Use Orion Connection 10 awg. power cable wire to extend the amplifier's positive
(+) power lead.
• Before installation, make sure the radio or control head unit POWER switch is in the OFF position.
• When making connections, be sure that each connection is clean and properly secured. Failure to do so may result in
damage to your equipment
• When replacing the amplifier's fuse, always use one having the same current rating. Using a higher-rated fuse or a slow-
blow type can result in serious damage to the amplifier.
• Never ground the speakers to the vehicle chassis or body. If this occurs, you can expect severe noise problems and, in
case of bridging, a canceling of the mono signal,
• Make sure that your vehicle has enough power to handle your current set-up and the newly installed amplifier and
accessories. If you are planning a multi-amplifier system, you may need to add a second battery and possibly a MBR 70.
• In an ideal wiring scheme the power wire from the amplifier is run along one side of the vehicle to the battery.
The remote turn-on wire and RCA audio cables are run down the center vehicle. The speaker wires
are run along the remaining side.
The idea is to keep signal groups away from each other. When wires are parallel to each other,
electro-magnetic fields generated by current flowing in the wires can cross<ouple and cause interfer¬
ence in the low-level audio cables. If two groups of wires must cross each other's paths, make sure
they are routed in a perpendicular fashion, as shown in Fig. 14,
