ROUBLE SHOOTING THE SYSTEM

We have put together this trouble-shooting guide if you experience problems after 

installing the amplifier. Please keep in mind that the majority of problems incurred are 

caused by improper installation and not the equipment itself. In addition, there are many 

components in the system that could cause various signal problems such as inducted 

electrical noise and engine noise.

Before you can properly address the problem, you must first find the component that is 

causing the problem. This will take patience and a process of elimination.

Ground at same point

 

Try different grounding point 

 

Change for better ground

 

Bad RCA cable(s)  

 

 

Replace

 

Use High Quality shielded RCA cables 

Rejects inducted noise

 

Low Vehicle charging system and/or battery  Fix and/or replace

Red Protection L.E.D. illuminated

 

Speaker short 

 

 

 

Check speakers connection

 

 

 

 

 

 

   for short circuit

 

Speaker grounding out 

 

 

Make sure speaker wires

 

 

 

 

 

 

Do not touch chassis ground

 

Impedance too low 

 

 

Check speaker impedance

 

Overheating 

 

 

 

Check mounting location

 

 

 

 

 

 

   for Adequate air circulation

 

 

 

 

 

 

   speaker impedance too low
