Trouble Shooting the System Specifications

TROUBLE SHOOTING THE SYSTEM

SPECIFICATIONS

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

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 Fix and/or replace

Check speakers connection for short circuit

Make sure speaker wires Do not touch chassis ground Check speaker impedance Check mounting location
