Troubleshooting
AMPLIFIER DOESN'T TURN ON:
• Verify that the cables are connected correctly. Make sure all connections have electrical
and mechanical contact.
• Fuses or circuit breakers may be defective or blown. Check the condition of the circuit
breakers and if it is compatible with the equipment consumption.
• Verify that the battery charge is sufficient for the operation of the product
NO SOUND:
• The cables of the speakers or connections may not be connected correctly or are defective.
PROT LED ON:
• Check for shorted speakers or cables, check speakers, cables and connections.
SOUND DISTORTIONS:
• Speakers may be overloaded or defective, turn down and re-adjust the level. This setting
can be adjusted as follows:
a) On the radio/player, put any musical signal and set the volume to 80% of maximum (if
the maximum volume of the radio/player is 45 (100%), set it to 36 (80%).
b) On the amplifier, with the GAIN control at minimum, gradually increase it until you hear
distortion in the speakers. Slowly return the GAIN until you notice that there is no more
distortion in the audio.
LACK OF BASS:
• Cables of the speakers may be reversed
and
(out-of-phase speakers).
NOISE AND FAILURE IN SOUND:
• Verify that the installation is not close to the original vehicle wiring as they may cause
interference and noise in the audio signal.
• Make a separate power connection to the sound system. Use a fuse/ circuit breaker as
close to the battery as possible for protection.
