Troubleshooting

If problems occur during the installation, or later,
this guide might help you to find out whats´s
wrong.
The amplifier is dead:
1. Check power lead, ground and connections 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:
One or more speaker cables are shorted. Make an
insulation test with a multi meter. The cables must
not have a connection to earth.

The amplifier turns off after 10-30 minu-
tes:
The amplifier is overheating due to inadequate ven-
tilation. Check mounting position is free from
obstruction.
Do this:
1. Move the amplifier to a place with better ventil-
ation.
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 the speakers:
Check the following:
1. Speaker cable connections to both amplifier and
subwoofers.
2. Signal lead plugs and cables.
