Verify that the LEVEL control isn’t at a minimum.

PROT LED FLASHING:

Verify that the product vents aren’t blocked or the product is overheated.
Speakers or cables shorted, check speakers, cables and connections.

SOUND DISTORTIONS:

The speakers may be overloaded or defective, lower the level and remake the level adjustment. This setting can be adjusted as follows:
- a) On the radio/player, place any musical signal and set the volume to 80% of the maximum (if the maximum volume of the radio /player is 45 (100%), set to 36 (80%).
- b) On the amplifier, with LEVEL control at minimum, increase gradually until the LED CLIP starts to flash. Slowly return the LEVEL until the led goes out completely.

LACK OF BASS:

Cables of the speakers may be reversed and (out-of-phase speakers).

NOISE AND FAILURE IN SOUND:

Verify that the installation isn’t 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.
Make a good grounding of the amplifier. To do this, remove the paint from the vehicle chassis at the desired point. Screw the wire using a ground terminal. To protect from oxidation, isolate with paint.
Don’t loop the ground. Avoid using multiple grounds. If possible, use a star connection, in which all the grounds run from a single point.
