If problems occour during the installation, or later, 
this guide might help you to find out what´s wrong.

THE AMPLIFIER IS DEAD:
1.

 Check power lead, ground and remote connec- 

    tions at the amplifier using a multi meter. 

2.

 Check the battery terminal connections.

3.

 Check the power lead fuse or circuit breaker. If 

    fuse damage continues, inspect the power lead 
    for short circuits. 

4.

 Check the amplifier protection fuses. Are these 

    broken change to new ones with the same value.  
    If short circuiting continues, contact your local 
    DLS dealer. A fault may exist in the amplifier. 

5.

 To start the amplifier requires a remote voltage of 

    9-15 volt. Check the voltage with a multi meter. 

AMPLIFIER PROTECTION FUSE BLOWS AT LOW 
VOLUME : 

1.

 One or more speaker cables are shorted. Make an 

insulation test with a multi meter. The cables must not 

have a connection to earth. 

AMPLIFIER TURNS OFF AFTER 10 - 30 MINUTES. 

The amplifier is overheating due to inadequate ventila-

tion. Check mounting position is free from obstruction. 

Do this:

1.

 Move the amplifier to a place with better ventilation.

2.

 Install one or two fans to cool down the heat-sink. 

3.

 Overheating can also be caused by an impedance 

    load below the level permitted. 

NO OUTPUT FROM ONE OR MORE SPEAKERS:

Check the following:

1.

 Balance control position.

2.

 Fader control position.

3.

 Speaker cable connections to amplifier and drivers

4.

 Signal lead plugs and cables.

5.

 Change left and right signal lead plugs in the 

    amplifier to see if the problem moves to a diffe-

    rent speaker, the lead has a fault. 

    If the problem remains, the speaker or amplifier  

    is at fault.

Troubleshooting Testing 

Before you finish the installation, you should do the 
following tests to make sure the wiring is correct and 
everything is operating properly.

Reconnect Battery

When wiring is complete, 
reconnect the battery 
negative terminal.

Test speaker connections

Make sure the speakers are connected right. Use 
the balance control on the head unit to make sure 
right channel is on right speaker etc. If speakers 
don´t play at all, one or both speaker wires may 
be disconnected.

Test power wiring

 1. Turn on the head unit but do not turn up the  
      volume. The amplifier power light should come  
     on. If not, check the remote and +12 volt wires.  
     Also check the ground connection.
 2. Turn up the head units volume slightly. All spea- 
     kers should operate. if not, check wiring    
     connections at amplifier and speakers.
