PROBLEM
LOOK FOR
No Output
Blown fuse
Bad RCA Cable(s)
+12V at power terminal
+12V at remote terminal
Grounding point are clean and tight
Head unit's fader not in center position
Master and slave settings
Low Output
Check level adjustments
Re-adjust
Bad RCA cable(s)
Improper level matching
Master and 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. illumintaed
Speaker short
Speaker grounding out
Impedance too low
Overheating

SOLUTION
Replace
Replace
Check connection
Check connection
Check for ground w/meter
Set to center position
Confirm correct setting
Replace
Re-adjust
Confirm correct settings
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 for
adequate air circulation.
Speaker impedance too low
