System tuning

TROUBLESHOOTING

1.  Install all system fuses.

 

2.   Set the amplifier’s input sensitivity controls to their minimum positions 

(full counterclockwise). 

3.   Set all amplifier crossover switches according to your system’s design. 

4.   Make preliminary adjustments to the crossover frequency, usually 80Hz 

is good starting point for high and low pass. It may be necessary to fine 

tune the crossover frequency later for the best overall sound quality. 

5.   If using a Remote Subwoofer Level Control, set it to maximum (full 

clockwise). 

6.   Turn the headunit on with the volume set to minimum.

 

7.  Visually check the amplifier’s has turned on by the power LED. 

 

8.   Check the condition of all other components to make sure they are 

powered up. 

9.   Set the headunit’s tone controls, balance, and fader to the center (flat) 

position. Turn off any loudness or other signal processing features. 

10.   Set the volume control of the headunit to  3/4 of maximum volume. Play 

music you typically listen to through the system. 

11.   Turn up the sensitivity or input level control on the amplifier until the 

speakers reach maximum undistorted output. 

12.   Repeat sensitivity level adjustments for all other amplifiers.

13.   Reduce the headunit’s volume to a comfortable level. 

14.   Listen to various musical selections to check overall system balance. 

Compare front to rear, midbass to midrange, etc. If one speaker set is 

too loud compared to another, then its level must be lowered to blend 

correctly with the other speakers. 

15.   Fine tune crossover frequencies to achieve the smoothest possible 

blending of each speaker set. 

16.   Adjust the Bass Equalization Controls on the amplifier, headunit or 

processor upstream if necessary to increase output.

 

 Note: Use these controls sparingly. Every 3dB of boost requires double the 

power at 45Hz. If your subwoofer system requires a lot of boost to sound 

good, there may be a problem. Look for out-of-phase woofers, a leaking 

subwoofer box, or incorrect box size. 

17.   With all levels set correctly, the system will reach overall maximum 

undistorted output at the volume level set in step 10.

NO POWER: 

Check voltage at the amplifier with a DMM (volt meter), +12v and R 

(with head unit on) the voltage should register between 11.5V and 

14.4V when using the attached ground lead of the amplifier. Check 

fuse 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 the fuse 

is blown, check the power wire and also the amplifier for a short. If 

the short is in the amplifier itself, see your Phoenix Gold dealer. If a 

short is not 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 correct, turn the amplifier on again.

NO SOUND FROM ONE OR MORE CHANNELS:

 

Check the balance control in the head unit. Check speaker 

connections. Check signal input connection. Very low output: Check 

your head unit’s fader control or the amplifier’s input sensitivity 

level. 

FREQUENT AMPLIFIER SHUTDOWN WITH AUTOMATIC 

RECOVERY: 

This indicates chronic amplifier thermal shutdown because 

of operation at consistently high internal temperatures. High 

operating temperature can be caused by inadequate ventilation. 

Make sure you are not running a lower than recommend 

impedance. Also check for damaged speakers or passive crossover 

systems. Finally, chronic thermal shutdown may result from 

otherwise normal operation of the amplifier at elevated output 

power levels, which can be resolved by providing additional 

amplifier cooling, installing a higher-power amplifier, or reducing 

amplifier output level.

POWER CYCLES ON/OFF QUICKLY: 

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 the battery. Check all ground 

connections.
