Connecting the Units

Note:

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

and negative grounding. Before installing it in a

recreational vehicle, truck, or bus, check the bat-

tery voltage.

• To avoid shorts in the electrical system, be sure

to disconnect the ≠ battery cable before begin-

ning installation.

• Refer to the owner’s manual for details on con-

necting 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.

• 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 ter-

minal of the auto-antenna. Such connection could

cause excessive current drain and malfunction.

• To avoid a short-circuit, cover the disconnected

lead with insulating tape. Insulate the unused

speaker leads without fail. There is a possibility

of a short-circuit if the leads are not insulated.

• 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 col-

• Route and secure all wiring so it cannot touch

any moving parts, such as the gear shift, hand-

brake 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.

ors 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 con-

nected to a terminal coupled with ignition switch

ON/OFF operations. If this is not done, the vehi-

cle battery may be drained when you are away

from the vehicle for several hours.

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

tion 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 capac-

ity of the lead will be exceeded, causing over-

heating.

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

the rating prescribed on the fuse holder.

• Since a unique BPTL circuit is employed, never

wire so the speaker leads are directly grounded

or the left and right ≠ speaker leads are com-

mon.

• Speakers connected to this unit must be high-

• 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 dam-

age to the products or fire.

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

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

control signal is output through the blue/white

lead. Connect to an external power amp’s system

• Cords for this product and those for other prod-

ucts may be different colors even if they have

the same function. When connecting this prod-

uct to another product, refer to the supplied

manuals of both products and connect cords that

have the same function.
