TROUBLE-SHOOTING 
SYMPTOM: POSSIBLE CAUSE
No power: Check voltage at amplifier with a DMM (volt meter), B+ and REM 
(with source unit on) the voltage should register between 12.2V-14.6V when 
using the attached ground lead of the amplifier.  Check fuse at amplifier and at 
the battery. Use a meter to verify connection from one end of the fuse to the 
other, breaks may not always be visible.  If fuse is blown, check the power wire 
and also the amplifier for a short.  If the short is in the power wire, repair it. If 
the short is in the amplifier itself, see your Phoenix Gold dealer.  If no short is 
present replace the fuse.  
Power without sound: Turn the amplifier off and check all input and output 
signal cables and power connections.  Check the speakers for shorts with 
a DMM (volt meter) or by connecting them to another audio source.  After 
making sure everything is normal, turn the amplifier on again.
Power without sound and status LED is lit red: The continuous red light of 
the power indicator signals a high internal operating temperature, which results 
in the amplifier switching off temporarily. When the amplifier cools down to a 
safe level, the amp will automatically restart. The continuous red light of the 
power indicator can also indicate a shorted speaker lead or battery voltage 
that is either too high or too low for proper operation.
No sound from one side: Check balance control. Check speaker connections. 
Check signal input connection.
Very low output: Check your source unit’s fader control.  Check the amplifier’s 
Input Sensitivity Level.
Frequent automatic amplifier shut down: This indicates that the amplifier is 
operating at a continually undesirable high internal temperature. High operating 
temperature can be caused by inadequate ventilation: Refer to the sub-section 
titled LOCATION for better amplifier location.  High operating temperature can 
also be caused by an excessively low impedance load. For instance below 
2 ohms stereo or 4 ohms bridged.  Check for bad speakers or bad passive 
crossover components. If all else fails, try rewiring the entire system.  High 
operating temperature can be caused by an incorrect input sensitivity level, 
refer to sub-section titled INPUT SENSITIVITY ADJUSTMENT.
“Motor Boating” - the power indicator going off repeatedly when the 
audio system is on:
 Check the amplifier’s connection to the battery.  Check 
battery voltage. If low, recharge or replace battery.  Check all ground 
connections.
Whining noise when engine is running: Reroute power cable from battery to 
source unit directly (include fuse), bypassing the battery terminal in the fuse 
box. Check power connections to be sure they are clean. Check the battery 
ground making sure the battery terminals and chassis ground are clean.  Run 
a ground wire from the source unit to the ground point of the amplifier and  
remove old source ground.
CAUTION: Do not disconnect the Power Amplifier’s ground when the
system is on. This could damage the amplifier.
