3. CONNECTING THE UNITS (UC MODEL)

- WARNINGS-

• When routing leads and cords, secure them with

cable retainers and electrician's adhesive tape. Also,

to prevent any damage to the insulation on the leads

and cords, protect them with electrician's adhesive

tape wherever they touch sharp edges. Be sure to use

a rubber O-ring grommet when routing wires through

metal, such as the firewall between the engine and

passenger compartments.

• Keep ail wiring away from hot surfaces or heater

outlets to prevent short circuits.

• Amplifier ground connections (Black) should only be

made to the vehicle's metal body or chassis for safety

reasons. The ground circuit carries the same current

as the power lead from the vehicle's battery. To get

good

contact when grounding, sand the metal

surface to expose the bare metal. If using multiple

amplifiers, connect all amplifier ground leads to the

same point to prevent noise problems.

• Always connect the supplied special (red) battery lead

directly to the positive (+) terminal of the battery.

• It is recommended that the speakers connected to the

amplifier have the minimum ratings shown below. If a

speaker has a rating below what is recommended, it may

be damaged when the volume is turned up. The speaker

impedance must be 2 to 8 ohms.

Mode

Speaker ratings

Two-channel

Maximum

200 W

Nominal

100W

One-channel

Maximum

600 W

Nominal

300 W

In the case of a fult-range speaker, use one whose

maximum rating is higher than the maximum rating

shown. In the case of a sub-woofer, use one whose nominal

rating is higher than the nominal rating shown.

• Never connect a speaker lead to ground or to other

speaker grounds. The protection circuitry will operate

instantaneously, turning off the amplifier.

• To prevent noise problems, keep the amplifier power

leads away from the signal cords {RCA cords) and

speaker leads. Also, keep the power leads away from any

antenna cords.

• Before finalizing the installation, turn everything on, and

make sure everything works correctly and listen for noise

in the system.

• For

detailed

information

connections

between

different units and the amplifier, use the instruction

manuals for the units. It is important to follow their

recommendations precisely.

Connecting the special red battery lead

Use the special (red) battery lead supplied with the amplifier.

This lead contains the appropriately rated fuse [30-amp fuse

(x2)]. This special (red) battery lead is made of heavy gauge

wire so it is capable of carrying substantial amounts of current.

Connect both of the two terminals at each end of the battery

lead securely. Should any one terminal come loose, there may

be a short circuit, perhaps causing electric shock or even a fire.

Route the special battery lead from the engine compartment

through the firewall or vehicle body to the passenger

compartment and connect it to the amplifier.

Drill an 14-mm diameter hole in the firewall or vehicle body

and insert an O-ring rubber grommet and pull the battery

lead through into the passenger compartment.

Note:

The O-ring rubber grommet is important because it protects

the insulation on the battery lead from being worn away from

normal vibrations and rubbing against sharp metal edges.

Failure to install this grommet could result in a short circuit

and fire.

While installing the wires, do not connect the positive (+) lead

of the battery until the other leads have been connected. This

will prevent accidental shorting to any other wiring or ground.

After making all other connections at the amplifier, connect the

battery lead terminal of the amplifier to the positive {+}

terminal of the battery-

vehicle body.

After all the other leads

have been connected,

connect both terminals

to the positive (+)

terminal of the battery

After making all other connections at the amplifier, connect the battery lead terminal of

the amplifier to the positive (+) terminal of the battery.
