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.

Diagnost Guide
In the eventuality of any problems, the amplifier will power down and the RED LED (PROT) light will begin to blink.
Depending on the problem, the RED LED (PROT) light will flash a certain number of times. The following table summarizes
the diagnostics:
Number of Flashes

or overload.
2
Overheating.
3
LOW
Low battery.
BAT

ge greater than allowed.
NOTE: In the event that the RED LED (PROT) light is flashing continuously, unplug the speakers and turn the
equipment back on. If the problem persists, contact STETSOM tech support.

The measured data are based on equipment from the STETSOM laboratory. Frequency reference of 1Khz with THD at ≤10% in
impedances referring to the indicated in each aparição. The electronic components and the manufacturing process can present
manufacturing variations, thus leading to a variation in the measurements made.

Solution
Check to make sure the speaker cables are
pro-perly isolated.
Verify minimum impedance.
Make sure the equipment is installed in a
well ventilated location.
When used for long periods, the battery will
run down. Recharge the battery.
Have the battery and/or alternator checked
by a professional.
