TROUBLE SHOOTING

NO FUNCTION / THE POWER LED IS NOT ILLUMINATED
First check the fuse of the routed power cable on the vehicle battery
The fuse is defective

Replace the defective fuse with an equivalent one, never with a higher value.
•  The fuse fails again.

In this case there appears to be a short circuit between the fuse and the amplifier. To do this, check 

the + 12V power cable along its entire length from the battery to the amplifier for damage and whether 

there is a short circuit to ground, e.g. a contact with the vehicle chassis or the body. If necessary, 

replace the defective power cable.

The fuse is apparently okay 

Use a standard 12 volt voltmeter to check the voltage between the + 12V connection and the ground 

connection on the amplifier. 
•  There is no voltage.

Use the voltmeter to check the fuse, which is located close to the vehicle battery, to see whether there 

is voltage between the output and ground.
If there is no voltage there, either the fuse holder or the fuse is defective, although it appears to be 

okay. If necessary, replace the fuse holder or fuse.

•  There is voltage.

If you operate the amplifier with a pre-amplifier signal (RCA), you must have laid a remote turn-on 

wire from the head unit to the REM terminal of the amplifier. The AUTO TURN-ON switch must be in 

the OFF position. However, you can test the AUTO TURN-ON switch to SIG. to see if the amplifier 

then turns on. If so, there is a problem with the control line..

•  A remote turn-on wire is connected to the REM terminal at the amplifier.

Use the voltmeter to check whether there is voltage between the REM terminal of the amplifier and 

ground. The head unit must be switched on.
There is no voltage.
•  Check the remote turn-on wire from the amplifier to the head unit for a short circuit or damage. 

If necessary, replace the control line.. 

There is voltage.
•  The amplifier is probably malfunctioning or defective. Contact your retailer.

If you operate the amplifier with the loudspeaker signals (high level mode), the AUTO TURN-ON 

switch must be switched to DC.

•  The AUTO TURN-ON switch is in the DC position, but the amplifier remains off.

Check the speaker cables from the head unit to the amplifier for short circuits or damage. If 

necessary, replace the speaker cables or insulate the damaged area.

ATTENTION: 

All instructions in this troubleshooting refer to the entire sound system and its individual components. 

The features of your device may not match the functions described in the notes. Then skip this point and move on to 

the next one.
