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.

LOOK FOR.....

No Output

Blown fuse

Bad RCA Cable(s)

+12V at power terminal

+12V at remote terminal

Grounding point clean and tight

Head Unit's fader not in center position

Master & Slave settings

Low Output

Check level adjustments

Re-adjust

Bad RCA cable(s)

Improper level matching

Master & Slave settings

Engine Noise

Grounding points are clean and tight

Ground all components at same point

Try different grounding point

Bad RCA cable(s)

Use High Quality shielded RCA cables

Low Vehicle charging system and/or battery Fix and/or replace

Red Protection L.E.D. illuminated

Speaker short

Speaker grounding out

Impedance too low

Overheating

SOLUTION

Replace

Check connection

Check for ground w/meter

Set to center position

Confirm correct setting

Replace

Re-adjust

Confirm correct setting

Check for ground w/meter

Ground at same point

Change for better ground

Replace

Rejects inducted noise

Check speakers connection

for short circuit

Make sure speaker wires

Do not touch chassis ground

Check speaker impedance

Check mounting location

for Adequate air circulation

speaker impedance too low
