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.
