External Amplifier Issues
5.1
Strong hiss
Reduce the input gain on the amplifier until the hiss is reduced to an acceptable level while still maintaining
performance. Note, if both amplifier and stereo output can produce distortion, the input gain is much
higher than it needs to be. In most situations, reduced gain levels will not produce detectable performance
conditions.
Put an RCA filter in between the radio “Line Out” connection and the amp. 2 of these can be put on
the connection to remove the feedback.
5.2
Amplifier volume fluctuates or amplifier turns off and on
•
Check the grounds to both amplifier as well as radio. Corrosion on any the contacts will reduce the ground.
•
Check system voltage while operating radio and amplifier. If the voltage fluctuates and drops below 11.5 volts,
load test the battery, check the charging system, and check all power and ground wires and contacts for
looseness or corrosion.
•
Ground the amplifier’s chassis to the stereo’s chassis.
5.3
Audio is extremely low
- check the amplifier’s gain setting and increase if necessary.
