Troubleshooting
Red power indicator off, no output:
• With Volt Ohm Meter (VOM) check:
1. +12V power terminal
2. Ground terminal
3. Remote turn-on lead
Red power indicator on, no output:
• Check RCA and connections
• Test speaker outputs with known good speaker
• Check function of source unit
• With VOM in AC volts position check RCA for signal
No output from one channel:
• Check RCA and speaker connections for that channel
• Swap RCA connections from left to right
• Swap speaker connections between channels
Yellow LED protection indicator is lit and there is no output:
Case 1: Amp is very hot
• 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.
• Short 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 RCA cable routing and condition. Keep RCA cables away from
all power wires.
