WARNING
Before installing your new amplifier, make sure the fuse is properly installed.
Never change the value of the fuses. Use the fuses with the current and rated voltage in this
manual. Otherwise, it may cause a short circuit, smoke or even an explosion.
Do not install this unit in a location that would interfere with operation of the vehicle or may
cause injury to a passenger as a result of breaking.
To ensure proper operation of this unit while maintaining good thermal dissipation, be sure to
leave enough space above the amplifier for proper ventilation. Do not cover the amplifier with a
carpet or blanket.
Connect the cable (+) battery to the positive terminal of the amplifier (B +) and ground wire
(GND) of the amplifier to the vehicle chassis.
This unit is for installation of 12V and negative grounding. Before performing an installation in a
van, truck or bus, check the battery voltage.
The black wire is the ground wire.
When installing this unit, always connect the ground wire first. Check the ground wire is properly
connected to the vehicle chassis.
If by some factor, the cable connected to the vehicle, is loosen or falls could result in fire, smoke
or failure.
The amplifier must be installed on a flat surface. Installing it on a surface that is flat or bumpy,
may cause defective operation.
Do not let this unit, contact with liquids that could lead to electric shock, smoke or overheating.
If by any problem with the instalation of this amplifier, the fuse blows. Disconnect the cables and
check all connections (power and speakers). Once you determine and solve the problem, replace
the fuse / s for a new nominal current and voltage identical.
If none of these works, contact your nearest dealer.

FEATURES AND DESCRIPTIONS
INSTALLATION
Connect the cable (+) battery to the positive terminal of the amplifier (B +) and ground wire
(GND) of the amplifier to the vehicle chassis. The cable terminal (REM) the terminal cable must
be connected to the stereo remote control
The black wire is the ground wire. When installing this unit, always connect the ground wire first.
Check the ground wire is properly connected to the chassis of the vehicle
Note
To prevent the ground wire (GND) to loosen or fall off the vehicle chassis, you can install a screw
and nut self-braking.

Troubleshooting
Before installing your amplifier, read the notes you see below and follow the procedures. Always
test the speakers and their cables before installing them in the vehicle.
No power
Check if the ground wire (GND) is properly installed.
Check dif the arrival of energy in the terminal (B +).
Check the fuses.
Check if the LED is turning it protection. it it is, turn the amplifier off for a few minutes and then on
again.
Shrill whistle or engine noise in speakers
Disconnect each of the RCA inputs on the amplifier until the hissing disappears. If the hiss disappears, then replace the cables. If by changing cables, whistling doesn´t disappear, check that the
main drive cables are not touching other wires of the vehicle.
The best way to establish the level of the amplifier is putting his gain to the maximum. Try to raise
the signal level on the main unit as much as possible and see if the hiss decreases.
Protection LED is activated when the amplifier is operating
Check for a short-circuit in the line of speakers.
Turn off the amplifier, disconnect all the speakers and turn on the amplifier. If the protection LED
turns on again, then is the amplifier is not working properly.
If the heat sink temperature exceeds 85° C, the power supply is disconnected automatically This
protecting the amplifier against a damage.
The amplifier overheats
Verify that the minimum speaker impedance is correct for the amplifier.
Check if the speaker wires have a short circuit.
Make sure if there is enough ventilation over the amplifier.
The sound is distorted
Verify that the gain control of the main unit is correct.
Check that all crossover frequencies are configured correctly.
Verify that the speaker wires are not touching each other.
Squealing noise in the speakers
The squeak maybe caused by a damaged cable or poor contact on the ground.
