! Use of this unit in conditions other than the
following could result in fire or malfunction.
— Vehicles with a 12-volt battery and negative
grounding.
— Speakers with 50 W (output value) and 4
ohm to 8 ohm (impedance value).
! To prevent a short-circuit, overheating or mal-
function, be sure to follow the directions
below.
— Disconnect the negative terminal of the
battery before installation.
— Secure the wiring with cable clamps or ad-
hesive tape. To protect the wiring, wrap ad-
hesive tape around them where they lie
against metal parts.
— Place all cables away from moving parts,
such as gear shift and seat rails.
— Place all cables away from hot places,
such as near the heater outlet.
— Do not pass the yellow cable through a
hole into the engine compartment to con-
nect to a battery.
— Cover any disconnected cable connectors
with insulating tape.
— Do not shorten any cables.
— Never cut the insulation of the power cable
of this unit in order to share the power
with other devices. Current capacity of the
cable is limited.
— Use a fuse of the rating prescribed.
— Never wire the speaker negative cable di-
rectly to ground.
— Never band together multiple speaker’s ne-
gative cables.
! Control signal is output through blue/white
cable when this unit is powered on. Connect it
to an external power amp’s system remote
control or the vehicle’s auto-antenna relay
control terminal (max. 300 mA 12 V DC). If the
vehicle is equipped with a glass antenna, con-
nect it to the antenna booster power supply
terminal.
! Never connect blue/white cable to external
power amp’s power terminal. Also, never con-
nect it to the power terminal of the auto anten-
na. Otherwise, battery drain or malfunction
may result.
! Black cable is ground. This cable and other
product’s ground cable (especially, high-cur-
rent products such as power amp) must be
wired separately. Otherwise, fire or malfunc-
tion may result if they are accidentally de-
tached.
