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 .
