POWER CONNECTIONS
Connect an empty fuse holder within 18” (45 cm) of the car battery,
and run 8 gauge (or heavier) cable from this fuse to the amplier
location. Then connect the fuse holder to the “BATT+”. Connect the
ground terminal to the closest point on the chassis of the vehicle.
Keep this ground wire to less than 39” (100 cm) 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.

LOW LEVEL INPUT WIRING
Low-level (RCA) input wiring is preferred for best audio performance.
Most trunk or hatchback installations will require a 15-20 feet (4-6
meters) RCA cable, while pickup trucks and under-seat installations
will require a 6-12 feet (1.8-3.6 meters) RCA cable. Always usa a high
quality cable. Connect to remote turn-on terminal head unit.
NOTE: do not connect BOTH the high level and low level
inputs from your receiver to your amplier at the
same time! Connect the remote level controller to
remote terminal.

HIGH LEVEL INPUT WIRING
The high level input(s) should only be use if the RCA output are not
present, connect the speaker outputs from the receiver to the high
level input connector of the amplier. Be sure to observe polarity to
avoid audio phase problems. Connect to remote turn-on terminal
head unit.
NOTE: do not connect BOTH the high level signal and low level inputs
from your receiver to your amplier at the same time!

TROUBLE SHOOTING
This amplier has multi-layer protection features to prevent
damage from misuse or faulty conditions to ensure long lasting life
of your investment. If the unit senses excessive heat, short circuited
speakers, overload, or voltage uctuation 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 amplier 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 amplier or make sure
nothing is covering it so it can vent heat off of the heatsink. Before
you remove or uninstall the amplier, 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, remov e and ground connection. It is possible f or
a fuse to have poor internal connections, take the fuse out of the
holder f or the 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 ensur e that the speak er wires are making a good
connection to the amplier and the subwoof ers.
Amplifier goes into protection:
• Check the chassis ground connections.
• Check amplier contr ols 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 amplier is
driving a load equal or greater than 2 ohm.
• Check the input signal cables to make sure signal is present at
the amplier inputs and the cables are not pinched or loose.
Ot may be helpful to try a different set of cables/or a different
signal source to be sure.
• Check speaker wiring for reverse polarity .

MISE EN GARDE
Merci d’utiliser l’amplificateur BLAM EX 320. Afin de garantir
les meilleures performances de votre amplificateur, nous
vous recommandons de lire ce manuel avant d’utiliser
l’amplificateur.
CONNEXION DE L’ALIMENTATION
Connection à la batterie (+12 Volts) : Connectez un câble de 8mm2
minimum avec un porte-fusible placé à moins de 45 cm de la
batterie de la voiture et reliez le à la connexion “BATT +”. Connectez
la masse (-) au châssis du véhicule au point le plus proche. Gardez
ce l de masse d’une longueur inférieure à un mètre. Utilisez un
câble de 8mm2 (minimum) (AWG 8). S’assurer que la surface de
contact est exempt de peinture ou de rouille an que le connexion
entre la cosse et le chassis soit efcace.

CÂBLAGE DES ENTRÉES BAS NIVEAU
Les entrées bas niveau (RCA) sont préférables pour de meilleures
performances audio, si votre autoradio est équipé de sorties
RCA. Les installations dans le coffre nécessite un câble RCA d’une
longueur d’environ 4 à 6 mètres tandis que les installations sous
le siège et l’habitacle nécessitent un câble RCA d’une longueur
d’environ 1,8 à 3,6 mètres.
Il est recommandé d’utiliser un câble de bonne qualité.
REMARQUES : Ne connectez jamais les entrées haut niveau et bas
niveau en même temps. Nécessite de connecter le câble de remote.
