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 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 various cords of 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 aif wiring so it cannot
touch any 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 orange lead through a
hole into the engine compartment to con-
nect to the battery. This will damage the
lead insulation and can cause a very dan-
gerous 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 sup-
ply lead of the unit and tapping into the
lead. The current capacity of the lead will
be exceeded, causing over heating.
When replacing fuses, be sure to use only
fuses of the rating prescribed on the fuse
holder.
Since a unique BPTL circuit is employed,
never wire so the speaker leads are di-
rectly grounded or the feft and right
speaker © leads are common.
+ Speaker connected to this unit must be
high-power types possessing minimum
rating of 35 W and impedance of 4 to 8
ohms, Connecting speakers with output
and/or impedance values other than those
noted here can damage the speakers,
When an external power amp is being
used with this system, be sure not to con-
nect the blue lead to the amp's power ter-
minal. Likewise, do not connect the blue
lead to the power terminal of the auto-an-
tenna. Such connection could cause ex-
cessive current drain and malfunction.
To prevent incorrect connection, the input
side of the iP-BUS connector is biue, and
the output side is black. Connect the con-
nectors of the same colors correctly.
When the unit is mounted in a vehicle
whose ignition switch does not have the
ACC (accessory) position as shown in
Fig. 7, be sure to connect the red lead of
the unit to the terminal controffed by the
ignition switch ON/OFF position. If you do
not, the vehicle battery may go flat when
you leave your vehicle for several hours.
