Connections
Note:
• Be aware that connection Is different between 2-speaker system and
4-speaker system. Failure to follow the wiring diagram may cause consid
erable loss of power even when fader control is at the center position.
• To avoid shorts in the electrical system, be sure to disconnect the battery
© cable before beginning installation.
• Replace fuses only with the types stipulated on the fuse holder.
• Be sure to properly connect the color coded leads. Failure to do so can
cause malfunctions.
• Cover unused terminals with tape to prevent electrical shorts.
• Refer to the power amp owner's manual when connecting a power amp
(sold separately) to the pin jack.
• Since a unique BPTL circuit is employed, never wire so the speaker leads
are directly grounded or the left and right speaker 0 leads are common.
• When a blue lead (system control terminal) is present on the power amp,
connect this lead to the unit's blue lead, and do not connect the unit's red/
white lead to anything. When the power amp does not have a blue lead
(system control terminal), connect the unit's red/white lead to the power
amp red lead.
