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.
