PROTECTION LED ON:
▪ Check the problem related to the protection LED that was triggered.
▪ Battery voltage outside of that supported by the product.
▪ Product operating at temperatures beyond the permitted limit. Ventilation
inlets and outlets on the product may be blocked, preventing the product
from cooling. Stop using the product until the temperature is normalized.
▪ Speakers or cables shorted, check the 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
NOISE AND FAILURE IN SOUND:
▪ Verify that the installation is not 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.
▪ 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.
