SYMPTOM

CHECK POINT

CURE

1.  Check fuses in amplifier

2.  Check turn-on lead

3.  Check signal leads

4.  Check gain control

5.  Check source unit volume

6.  Check fader control on source unit

7.  Clean all contacts 

Check speaker for short or 

amplifier for overheating

Check impedance with Ohm meter

If no reading, replace speaker

Check that the speaker moves freely

If speaker won't move, replace speaker

Check that speaker is secured properly

Tighten mounting screws

and tightened with screws

Check enclosure construction

Check that the enclosure has no debris

Check speaker polarity

Correct polarity

NO SOUND FROM

1.  Inspect for short circuits

ONE VOICE COIL

2.  Check for open connections

Reverse left and right speaker leads to 

determine if it is occurring before the speaker

Confirm that the speaker load impedance

recommendations are followed.  Check the 

wiring configuration of the speakers.  (To verify

proper load impedance, use an OHM meter to

measure the total load for each channel of the amplifier.

Verify that amplifier and / or crossover

Select low-pass setting

Is the amplifier power LED illuminated?

Is the amplifier overload LED illuminated?

for the amplifier.

Check speaker load impedance capabilities

Check speaker leads

AT HIGH VOLUME

SPEAKER IS DISTORTING

A RATTLING NOISE

SPEAKER IS MAKING

NO SOUND
