NOTES OF CONNECTION
■ This unit is designed to be used in a vehicle with a 12-volt battery and negative
grounding. Before installing this unit to a mobile home, a bus, or a truck, make sure the
battery voltage is appropriate for this unit to be used, otherwise, install a transformer
to convert the output voltage to 12 V.
■ To avoid short circuit in the electrical system, ensure that the negative battery cable is
disconnected before installation.
■ To prevent short circuit in the wiring and damaging to this unit, secure all wirings with
cable ties or adhesive tape. Route the wirings in a secured, out of heating place without
touching any moving parts such as gear shift, handbrake, and seat rails to prevent the
wiring insulation being melted/wore off.
■ Never pass the yellow power cord through the installation hole into the engine
compartment and connect to the car battery. Otherwise, a high possibility of serious
short circuit to the electrical system may occur.
■ Replacing a new fuse with 10 A rating when the old one is broken, using no fuse or
fuse with improper rating may cause damage to this unit or even fires. lf a proper fuse
is installed and electrical problems still occur, please contact with any professional car
shops for inquiry.
■ Please make sure all the wiring connections and the cables of the speakers are well-
insulated. Otherwise, this unit may be damaged by short circuit.
■ lf there is no ACC available, please connect ACC lead to the power supply with a swit
ch.
■ lf an external power amplifier is connected, please don't connect P.CONT lead to the
power lead of the external power amplifier, otherwise, electric spark or other damage
may be resulted.
■ Never ground the speaker output to prevent the damage to the built-in power amplifier.
■ The minimum rating of the speakers connected to this unit is 50 W with 4 to 8
impedance.
