Installation of the Speaker Outputs
The speaker cables should be polarized (marked) so that you can easily identify which is positive and which is negative.
Minimum gauge is 8 AWG. Keep the cables well insulated and avoid metal parts as these may damage the insulation.

Troubleshooting

NO POWER:
• The power cables are not connected correctly (terminals +BAT, GND and REM). Verify that all the connections have
electrical and mechanical contact.
• The fuse/circuit breakers are defective or blown. Replace them, making sure that the replacements are the correct ones!
NO SOUND:
• The speaker cables or RCA plugs are not connected correctly.
• Verify that the LEVEL control is at the lowest setting. Check the amplifier filter controls.
NO SOUND. RED ALERT PROT BLINKING:
• See diagnostic guide
• The speakers or cables are defective, so check speakers, cables and connections.
POOR SOUND QUALITY (DISTORTIONS):
• The speakers are overloaded. Decrease and readjust the volume level (see entry, "LEVEL (LEVEL CONTROL)")
WEAK BASS:
• Speaker cables (+) and (-) are switched or the speaker is out of phase (see entry "INSTALLATION OF THE SPEAKER
OUTPUTS"). Also check BASS control adjustment.
ENGINE, HORN, TURN SIGNAL, INTERFERENCE:
• Use suppressing/insulated cables on the spark plugs.
• Use capacitors on the alternator, horn and ignition.
• Run the shielded input cable away from any other cables, as they are particularly prone to interference.
• Install a separate power source (+12V) for the sound system. Use a fuse/circuit breaker 30 centimeters from the
battery as the best precaution.
• Ground the amplifier properly. Remove paint from the chassis at the selected point, and connect the wire using a
grounded terminal. In order to prevent rust, insulate it with paint.
Do not loop the ground. Avoid using multiple grounds. If possible, use a star connection, in which all the grounds run
from a single point.
