TROUBLESHOOTING TIPS
Problem Solution
Power LED not ON
With a Volt Ohm Meter (VOM) check:
* +12 Volt power terminal (should read +12 to +16VDC
* Remote turn-on terminal (should read +12 to
+16VDC)
* Ground Terminal
Power LED is GREEN, no output
* Check RCA connections
* Test speaker outputs with known good speaker
* Substitute 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 10-16.8 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 can 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. Contact Gladiator or your local dealer.
