HOW TO TROUBLE SHOOT A SYSTEM
GENERAL
A car stereo system consists of many different pieces of equipment
connected together, and a logical process of elimination will find the
problem area, by isolating sections, and checking them one at a time.
Before following the instructions below, check and double check all
wiring and connections.
TOOLS NEEDED
The following tools will help in finding problems:
A general purpose multi meter, capable of checking voltage and
resistance, is perhaps the most useful piece of test gear that any installer
can own.
You may also need a test speaker, and a head unit, as these will be handy
for temporary connection for checking purposes when you are working
in the trunk of the vehicle.
NO SOUND
This is probably the most perplexing problem to find.
1. Reduce the amp gain to 9 volts and unplug the RCA cables and speakers
from the amplifier.
2. Check with your multi meter that each amplifier in the system has
proper 12 volt DC supply on it is power terminals.
3. Also check that the remote turn on terminal has 12 volt on it.
If all seems well, and the amplifier power indicators lights without any
diagnostic light:
4. Connect the head unit RCA directly to the amplifier (eliminating any
signal processors which you may have installed in between the head unit
and amplifier) and turn on the system.
If the power LED is on with no Diagnostic LED, continue:
5. Connect each speaker one at a time to see which speaker puts the amp
in diagnostic.
By utilizing this process of elimination you can determine where the
cause of the problem is. If the amplifier goes in to diagnostic with
nothing connected to it, and you are sure of proper power and
ground, please contact our service department for further help a 732
