Troubleshooting
Noise problems
Check the power light is turned on or not.
do that:
1.check the fuse.
2.check the power cable connection.
3.check the signal wire.
4.check the gain control.
5.Check the volume of head unit and other equipment.
6.Clear the contact surface for fuse holder.
Check if the LED display is overload.
Method: check if the speaker is short out or the amplifier is overheating.
The amplifier is dead
Check the battery terminal connections.
Method: repair the power cable or reconnection.
The control cable of head unit isn't connected.
Method: check the front equipment is connected or not
The fuse is fault
Method: change the fuse
A channel without sound
Check the driver wire
Method: check if power is short out or open circuit.
Method: both of driver and amplifier are connect correctly,
then it must the input connection is wrong.
The amplifier will be turned off when the tweeters in high volume.
Check the impedance of speakers
Please check the below suggestion about the impedance of speakers and
check the speaker connection.(We will use the same ohm gauge to test
load all channels, ensure the loads are suitable.)
