Troubleshooting
The LED mounted on the end panel of the amplifier lights up in two different colors depending on the condition of the amplifier Green indicates that the amplifier is turned on and no trouble exists When it turns red this indicates that the protection circuit has been engaged The LED on the top of the amplifier chassis indicates that the amplifier is on When the protection circuit is engaged, this LEDturns off
Green power indicator off, no output:
lWith Volt Ohm Meter (VOM)check 1 +I 2v power terminal
2 Ground terminal
3 Remote
Green power indicator on, no output:

Check RCAand connections
Test speaker outputs with known good speaker Check function of source unit
With VOM in AC volts position check RCAfor signal
No output from one channel:
l
l
l
Check RCAand speaker connections for that channel Swap RCAconnections from left to right
Swap speaker connections between channels
Red LED protection indicator is lit and there is no output:
Case 1: Amp is very hot
l Thermal protection is engaged Check for proper impedance at speaker terminals Also check location of amplifier to ensure proper air flow around heatsink
Case 2: Output resumes momentarily when system is turned off and back on
lShort circuit protection is engaged With VOM check for short between speaker positive and negative, and between speaker terminals and ground
Alternator noise (a whining that varies with engine RPM)

Make sure that the ground for the source is as short as possible and connected to bare chassis metal The stock radio ground may not be sufficient
Check RCAcable routing and condition Keep RCAcables away from all power wires
