TROUBLESHOOTING
1. POLARITY
It is a good idea to test the polarity of the speaker and wire connection. Testing the polarity confirms
that positive (+) wire is connected to the positive (+) terminal on the speaker and amplifier. A reverse-
polarity connection (positive (+) wire connected to negative (-) terminal) will result in poor speaker
performance and possibly damage the system.
To test the polarity, take a 9 Volt battery. Connect the negative (-) terminal of the 9 Volt battery to the
negative (-) wire. Then, while observing the woofer on a speaker, connect the positive (+) terminal of
the 9 Volt battery to the positive (+) wire.
If the woofer on the speaker moves outwards, the wiring polarity is correct. If the woofer on the
speaker moves inward, the wiring polarity is incorrect. In this situation, it is best to correct the polarity
by swapping the positive (+) and negative (-) wire on back of the speaker.
2. CHANNEL CHECK
To check that the left speaker is not connected as a right speaker, you will need an amplifier or
preamplifier that has BALANCE control. Turn on the system so that music is coming from the speaker
system. Move the BALANCE control to the far right. The right speaker should only be producing
sound. Move the BALANCE control to the far left. The left speaker should only be producing sound.
If the above case is not true, then it would be easiest to correct the problem at the equipment rack.
The problem may not be at the amplifier to speaker connection. It is a good idea to check source to
amplifier connection as well.
3. NO SOUND FROM SPEAKER
In the event that no sound from the speaker is heard, check the wiring or the items below.
A. Verify the correct source is playing and is selected on the receiver\amplifier end.
B. Verify mute and volume levels are correct. Verify volume control is wired properly.
C. Some receivers have A or B selector switches, verify the correct output is switched. This also
applies to speaker selector switches and advanced volume controls.
D. A wire short-circuit may cause the amplifier to shut-down in protection mode.
E. Bad connecting between the source and receiver\amplifier end.
