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.

Set to center position

Low Output

Check level adjustments

Re-adjust 

Bad RCA cable(s)

Replace

Improper level matching

Re-adjust

Engine Noise

Grounding points are clean and tight

Check for ground w/meter

Ground all components at same point

Ground at same point

Try different grounding point

Change for better ground

Bad RCA cable(s)

Replace

Low Vehicle charging system and/or battery

Fix and/or replace

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
