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.
