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.
