TROUBLESHOOTING TIPS
Problem Solution
Power LED not ON
With a Volt Ohm Meter (VOM) check:
* +12 Volt power terminal (should read +11 to +15VDC
* Remote turn-on terminal (should read +7 to +16VDC)
* Ground Terminal
Power LED lights BLUE, no output
* Check RCA connections
* Test speaker outputs with Well known good speaker
* Substitute Well known good Source Unit
* Check for signal on the RCA cable with VOM
in AC position
Protection LED is ON, no output
and
1. Amp is VERY HOT
* Thermal protection is engaged. Check for proper
Impedance at speaker terminals. Also check for
Adequate air flow around the amplifier.
2. Amp shuts down ONLY when the
* Voltage protection engaged. Voltage to the amp is
vehicle is running
not within the 10-15 VDC operating range. Have the
battery /charging system inspected.
3. Amp plays at very low volume
*Short circuit protection is engaged. Check for speaker
wires shorted to each other or the vehicle chassis.
Speakers operating below the minimum impedance an
cause this to occur.
Alternator noise (varies with RPM)
* Check for damaged RCA cable.
* Check routing of RCA cable
* Check Source Unit for good ground
* Check amp gain setting, turn down if set too high
Poor Bass Response
* Check speaker polarity, reverse the connection
of one speaker only.
NOTE: If the Red protection L.E.D. is activated with no speakers connected to the amplifier,
and all the power connections are correct, this would indicate an internal problem with the
amplifier..
