Installation
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
battery voltage.
• To avoid shorts in the electrical system, be sure
to disconnect the
·
battery cable before begin-
ning installation.
• Refer to each product’s manual for details on
connecting the power amp and other units, then
make connections correctly.
• Secure the wiring with cable clamps or adhe-
sive 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 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 out-
let. 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 bat-
tery. This will damage the lead insulation and
cause a very dangerous short.
• 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 cut-
ting 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 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 common.
• Speakers connected to this unit must be high-
power types with minimum rating of 45 W and
impedance of 4 to 8 ohms. Connecting speak-
ers with output and/or impedance values other
than those noted here may result in the speak-
ers catching fire, emitting smoke or becoming
damaged.
• 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 sys-
tem remote control or the car’s Auto-antenna
relay control terminal (max. 300 mA 12 V DC).
If the car features a glass antenna, connect to
the antenna booster power supply terminal.
• 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 disconnect-
ed lead with insulating tape. Especially, insu-
late the unused speaker leads without fail.
There is a possibility of short-circuiting 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 colors correctly.
