◆
The product is used for such cars with 12V battery and negative grounding ,
before installing this product on these cars with 24V batteries,such as truck,bus,
big coach etc.cars), please install the reduction voltage equipment firstly.
◆
To avoid short circuit of the electrical system , please firstly switch off the
negative electrode terminal's wire of the batter before installing it .
◆
Please arrange the wiring in some place where can be fixed, thus, keep it no way
to touch any moving parts , such as the handbrake ,gear lever, etc ; Do not arrange
the wiring in the heat source area , such as near the heater discharge outlet ,
otherwise,the heat source will cause the wiring insulation layer was melted or
worn,thus,it will cause short-circuit between the wiring and the car body .
◆
When replacing the blown fuse ,you must use (10A) fuse as ruled. If use high -
capacity rated fuses to replace ruled fuses, or no use fuses to direct connect,
very easy to cause a fire ordamage the device.
◆
Do not let the yellow power cord go through the engine mounting hole and
introduced with warehouse positions to connect the battery , otherwise, it may
damage the power line,then, it will cause short circuit between power line and
car body .
◆
Do not connect this product's power line with other devices's power lines ,
otherwise, it will cause overloading to change overheating.
◆
Please use insulation paste to wrap the leading wire of unused speaker, so as to
avoid(prevent) short circuit,please ensure that the leading wire of unused
speaker gets insulation, otherwise it will cause a short circuit.
◆
Please ensure that keep any exposed wires to get insulation,meanwhile,bundling
all electric wires very well , avoiding any connection terminals to touch the
metal parts of this device's body,thus, it can prevent short sircuits.
◆
If your car's ignition does not have ACC position , please use ignition switch key
to connect ignition wire/lead onto this on/off power source.
◆
When turning on the power source , external power amplifier control signal
leads AMP. CONT outputIf this device(unit) connected an external amplifier ,
please do not connect AMP. CONT leading wire to the end of power amplifier,
otherwise, it will cause electric leakage and fault.
◆
For this product, forbidden its loudspeaker output terminals to connect ground
wire,otherwise it will burn out the amplifier. Do not use such loudspeaker system
with the common ground wire and three kinds of wires styles,no permitting to
connect the loudspeaker to car body.
◆
The loudspeaker which connects this device(unit) must be high-power type, the
minimum rated value is 50W, impedance values(resistance value) is
4Ω
, please
don't directly connected a severalof speaker leads or impedance values
(resistance value) outside of this range, otherwise,it will cause short circuit and
damage the loudspeakers.
