The amplifier may be bad with a malfunctioning circuit inside. Also, it could be getting low voltage...make sure that the amp is getting 12 volts or more at the constant and remote leads. If it is connected to speakers, make sure that they are measuring more than 2 ohms (using a voltmeter). A good stereo shop can check this for you too.

Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.

1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.

2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.

3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
system.

Well, I have no idea why you would have two capacitors on a 500 watt amp but, did you charge the capacitors? Have you tried the amp without the capacitors? What size power wire are you using?

Amp burned out but fuses still good?


this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

JBL GTO 301.1ii protect mode


Hello roets81,

Check the voltage at the amp. It's possible that the voltage is either too high (above 16V) or too low (below 8.5V). Also make sure that the amp case is not grounded. If these check out OK, the most likely cause is that the amp itself is defective and requires service.

Hope this helps.

Turn the system off and disconnect the speakers. Turn the system on. If the amp still goes into protection mode with no speakers connected, then most likely the output transistors are bad. If the protection light is off, hook up one sub at a time until you find the one that is causing the problem

Amp heats up and goes into protect mode


Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.
