that the unit will not interfere with the nor-
mal driving functions of the driver and that
the unit will not be exposed to direct sun-
light or hot air from the heater. Do not install
the unit under the floor carpet, where the
heat dissipation from the unit will be con-
siderably impaired.

ona level surface on an inner trunk support
and drill the boit holes 3 mm (?/, in.) in dia.
2Secure the unit to the support.
If the support is thin, drill bolt holes of 3mm
('/, in.) in diameter, then screw the bolts into
these holes and secure them with nuts. If

CONNECTIONS
Caution
*Before making connections, disconnect
the ground terminal of the car battery to
avoid short circuits.
* Connect the red power input lead only af-
ter all other leads have been connected.
Run all ground wires to a common ground
point.
SPEAKER CONNECTION
*Since the XM-601 employs the BTL
(balanced transformerless) circuit system,
be sure to make speaker connections as il-
lustrated.
If the connection is made through already
existing speaker leads which have a com-
mon © lead for both right and left chan-
nels, it is possibile that the amplifier and
the speaker system will be damaged.
*Do not connect the © terminal of the
speaker system with the car chassis, and
do not connect the © terminal of the right
speaker with that of the left speaker. Doing
so will damage the XM-601.

Notes
*4-speaker system is possible even when
using a car stereo equipped with one out-
put connecting cord. In that case, connect
the output connecting cord of the car
stereo to the MAIN input jacks of the XM-
601. The sound will be heard from both
front and rear speaker systems.
* The levels of the MAIN speaker system and
SUB speaker system can be adjusted with
the LEVEL ADJ controls also when con-
necting the output connecting cord of the
car stereo only to the MAIN input jacks of
the XM-607.
