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.
