NOT TURN ON:
- The cables are not correctly connected (terminals BAT, GND and REM). Make sure that all
connections has mechanical and electrical contact.
- Fuses/circuit breakers (external) are defective or burned. Take care about the correct value of
the new fuse!
- Output remote/electric antenna of CD-player/MP3-player with problem (burn).
NO SOUND:
- The cables of speakers or plugs RCA are not connected correctly.
- Check if the LEVEL control is not in the minimum.
NO SOUND / RED LED (PROTECTION) ILLUMINATED:
- Speakers or cables (damaged), so, check speakers, cables and connections.
- Check the battery charge.
BAD SOUND QUALITY (DISTORTION):
- The speakers are overloaded, so, decrease the level and redo the gain adjustment (see iten
2/general description).
WEAK BASS:
- Cables of speakers (+) and (-) are changed, speakers out of phase (see iten 5/general
description).
MOTOR NOISE, HORN, SIGNAL LIGHT, ETC:
- Use suppressive cables in ignition candles.
- Use capacitors in the alternator, horn, ignition.
- Pass the shielded RCA cable away from any other cable, because it is more sensitive to
interference.
- Connect to power (+12V) separate for the sound system. Use a fuse to 30 cm from the battery
for protection.
- Make a good grounding of the amplifier. To do this, remove the paint from the chassis of the
vehicle at the desired point. Screw the cable using a ground terminal. To protect from
oxidation, insulate with paint.
- Do not loop the ground wire. Avoid using several ground wires. Prefer a star connection, with all
the ground wires aside from a single point.

Summary

Troubleshooting Common Issues

Not Turning On

Ensure cables are correctly connected and fuses are intact for power issues.

No Sound

Check speaker connections, RCA plugs, and ensure the LEVEL control is not at minimum.

No Sound; Red LED (Protection) Illuminated

Inspect speakers/cables for damage and check battery charge.

Bad Sound Quality (Distortion)

Reduce speaker level and readjust gain if sound is distorted or overloaded.

Weak Bass

Verify speaker polarity to avoid phase cancellation causing weak bass.

Motor Noise, Horn, Signal Light, Etc.

Use shielded cables for RCA and proper grounding to prevent interference.
