Connecting the Units

MANUEL

Note:

• This unit is for vehicles with a 12-volt battery and

negative grounding. Before installing it in a recre-

ational vehicle, truck, or bus, check the battery

voltage.

• To avoid shorts in the electrical system, be sure to

disconnect the ≠ battery cable before beginning

installation.

• Refer to the owner’s manual for details on

connecting the power amp and other units, then

make connections correctly.

• Secure the wiring with cable clamps or adhesive

tape. To protect the wiring, wrap adhesive tape

around them where they lie against metal parts.

• Route and secure all wiring so it cannot touch any

• When an external power amp is being used with

this system, be sure not to connect the blue/white

lead to the amp’s power terminal. Likewise, do not

connect the blue/white lead to the power terminal

of the auto-antenna. Such connection could cause

excessive current drain and malfunction.

• To avoid short-circuiting, cover the disconnected

lead with insulating tape. Especially, insulate the

unused speaker leads without fail. There is a possi-

bility of short-circuiting if the leads are not insulat-

ed.

• To prevent incorrect connection, the input side of

the IP-BUS connector is blue, and the output side

is black. Connect the connectors of the same

moving parts, such as the gear shift, handbrake and

seat rails. Do not route wiring in places that get

hot, such as near the heater outlet. If the insulation

of the wiring melts or gets torn, there is a danger of

the wiring short-circuiting to the vehicle body.

• Don’t pass the yellow lead through a hole into the

engine compartment to connect to the battery. This

will damage the lead insulation and cause a very

dangerous short.

• Do not shorten any leads. If you do, the protection

circuit may fail to work when it should.

• Never feed power to other equipment by cutting

the insulation of the power supply lead of the unit

and tapping into the lead. The current capacity of

the lead will be exceeded, causing overheating.

• When replacing fuse, be sure to use only fuse of

the rating prescribed on this unit.

• Since a unique BPTL circuit is employed, never

wire so the speaker leads are directly grounded or

colors correctly.

• If this unit is installed in a vehicle that does not

have an ACC (accessory) position on the ignition

switch, the red lead of the unit should be connected

to a terminal coupled with ignition switch ON/OFF

operations. If this is not done, the vehicle battery

may be drained when you are away from the vehi-

cle for several hours. (Fig.1)

the left and right ≠ speaker leads are common.

• Speakers connected to this unit must be high-

power types with minimum rating of 50 W and

impedance of 4 to 8 ohms. Connecting speakers

with output and/or impedance values other than

those noted here may result in the speakers

catching fire, emitting smoke or becoming dam-

aged.

• When this product’s source is switched ON, a con-

trol signal is output through the blue/white lead.

Connect to an external power amp’s system remote

control or the car’s Auto-antenna relay control ter-

minal (max. 300 mA 12 V DC). If the car features

a glass antenna, connect to the antenna booster

power supply terminal.

•The black lead is ground. Please ground this lead separately from the ground of high-current prod- ucts such as power amps.

If you ground the products together and the ground becomes detached, there is a risk of damage to the products or fire.

•Cords for this product and those for other products may be different colors even if they have the same function. When connecting this product to another product, refer to the supplied manuals of both products and connect cords that have the same

function.

With a 2 speaker system, do not connect anything to the speaker leads that are not connected to speakers.

Perform these connections when using the optional amplifier.
