TROUBLE 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....	SOLUTION
No Output
Blown fuse		Replace
Bad RCA Cable(s)		Replace
+12V at power terminal		Check connection
+12V at remote terminal		Check connection
Grounding point clean and tight		Check for ground w/meter
Head Unit's fader not in center position		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
Use High Quality shielded RCA cables		Rejects inducted noise
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
Impedance too low		Check speaker impedance
		(Min 2 ohm Stereo, 4 ohm Bridged)
Overheating		Check mounting location
		for adequate air circulation.
		Speaker impedance too low
