POWER CONNECTIONS
Connect an empty fuse holder within 18’’ (45 cm) of the car battery
and run 8 mm² (8 gauge) cable from this fuse to the amplifier
location. Then connect the fuse holder to the battery +12 Volts.
Connect the ground terminal to the closest point on the chassis of
the vehicle. Keep this ground wire to less than 39’’ (1 m) in length.
Ensure that the contact surface is free of paint or rust so that the
connection between the terminal and the chassis is effective.
The +12 V remote turn-on wire is typically controlled by the source
unit’s remote turn-on output.
The amplifier will turn on when +12 V is present at its remote (REM)
input and turn off when +12 V is switched off. Connect the remote
wire using 1 to 3 mm² (12 to 16 gauge) wire to the REM connection
of the amplifier with Allen screw driver than connect the other end
of the remote wire to either the source unit’s turn on output or
ignition switch circuit.

LOW LEVEL INPUT WIRING
Low-level (RCA) input wiring is preferred for best audio performance.
Most trunk or hatchback installations will require a 4-6 m
(15-20 feet) RCA cable, while pickup trucks and under-seat
installations will require a 2-4 m (6-12 feet) RCA cable. Always use a
high-quality cable. Connect to remote turn-on terminal head unit.

TROUBLE SHOOTING
This amplifier has multi-layer protection features to prevent
damage from misuse or faulty conditions to ensure a long-lasting
life of your investment. If the unit senses excessive heat, short
circuited speakers, overload, or voltage fluctuation outside of the
working range the protection indicator light will turn red and the
unit will turn off.
In order to solve this problem, you should turn all levels down,
power off the unit, then carefully check the installation for
wiring mistakes or shorts. If the amplifier is excessively warm the
protection light will not turn on as the unit will turn off to protect
itself from overheating. Let the unit cool down for 30 minutes and
try again. If the unit work, try moving the amplifier or make sure
nothing is covering it so it can vent heat off of the heatsink. Before
you remove or uninstall the amplifier, refer to the list below for
suggested solutions.
Amplifier doesn’t turn on or not output:
• Check the fuse(s), not just visually, but with a continuity meter
and all 12+ volt, remote and ground connection. It is possible for a
fuse to have poor internal connections, take the fuse out of the
holder for testing.
• Check the input signal from the source unit using an AC voltmeter
to measure the voltage while it’s being played. The voltage should
be from 0.3 to 15 volts from the RCA cables.
• Check to ensure that the speaker wires are making a good
connection to the amplifier and the subwoofers.
Amplifier goes into protection:
• Check the chassis ground connections.
• Check amplifier controls for errors, input level or crossover
setting.
• Check the speaker wires for a possible short, either between the
positive and negative leads or between a speaker lead and the
vehicle’s chassis ground.
• Check the nominal load impedance to verify that the amplifier is
driving a load equal or greater than 1 Ω.
• Check the input signal cables to make sure a signal is present
at the amplifier inputs and the cables are not pinched or loose.
It may be helpful to try a different set of cables/or a different
signal source to be sure.
• Check speaker wiring for reverse polarity.

CONNEXION DE L’ALIMENTATION
Connecter un câble de 8 mm² minimum avec un porte-fusible
placé à moins de 45 cm de la batterie de la voiture et reliez-le à la
connexion ‘’+12V’’.
Connecter la masse (-) au châssis du véhicule au point le plus
proche. Garder ce fil de masse d’une longueur inférieur à un mètre.
S’assurer que la surface de contact est exempte de peinture et
de rouille afin que la connexion entre la cosse et le châssis soit
efficace.
Connecter la télécommande en utilisant un câble de 1 à 3 mm² au
bornier REM de l’amplificateur et à la source d’alimentation ou au
commutateur d’allumage.
