Hi!

I know you say all your cabling is correct and I don't doubt you at all. However, the problem you describe sounds an awful lot like a short or an impedance problem with your speaker wiring. Make sure that the ohm ratings for your speakers are correct for your amp, make sure that the + and - wires for each speaker don't touch each other (especially easy to do where they connect to the amp), make sure that no speaker wires are cut or crimped (easy to do if you are burying under a baseboard or something), and finally make sure that all the speakers are wired correctly and are in phase.

A good test procedure is to remove all speaker connections from the amp. Then run new (test) wires from the amp to just your front speakers or to two known-good speakers with correct ohm impedance. If the receiver works that way, it tells you that you have a problem somewhere in your wiring.

Good luck and please let me know if this helps.

How do i fix my Power Acoustik LT-980/2 car amp, it keeps on going into protect mode.


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty . .A thumbs up would be greatly appreciated if this answer is helpful to you

Gos in to protection mode as soon as you aplly power


Check for a short circuit in the wiring of the output speakers or a shorted speaker voice coil, also check for correct voltage to the POWER AMP while in use... when an AMP goes in protective mode this means two things A SHORTED OUTPUT or A INCORRECT VOLTAGE TO THE POWER AMP. if all the above is OK than the AMP is defective. are you using correct speakers OHMAGE 4, 6 8ohms??? according to your AMP.

Good luck!

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.

My Sony XMGTR2022 goes into protect mode at


I discovered that there is a compatiblilty problem between the Bose receiver and the Sony amplifier. If I disconnect the receiver from the amp then the amp starts up normally. Apparently the receiver sends out a dc offset or a "thump" that the amplifier doesn't like and goes into protection mode. I solved the problem by putting a 1 second delay circuit between the receiver startup and the amplifier startup. A simple RC delay on the remote input to the amplifier solved the problem.

My amp automatically goes into protect mode


There are 4 reasons an amplifier tries to protect itself.

Overheating - thermal shutdown.

Over Impedence - The subwoofers installed are not configured into a load the amplifier can handle.

Output is grounded - a positive wire strand may be touching the ground terminal - a wire may be shorted, or a speaker voicecoil is blown.

Intennal problem - Output on amplifier blown, or some other component has failed.

Check your wiring to the amplifier again - if all is good - disconnect the speakers and try to power on. If the amplifier turns on normally - test the speakers for blown coils.

If the amplifier still goes into protect mode - the problem is internal and needs professional repair.

Amp on "protect" mode


Hi, what you need to do is unplug all the connections to the amp. The amp goes into protection when the circuitry over heats.\
First decrease all your gains to minimal volume.
Connect your 12+V, remote, and ground.
See if the protection light comes on then.
Next plug in your RCA cables.
Check protection light.
Then plug in your subwoofer cables.
See if you are still in protect mode.
Hopefully everything works alright again.
Just slowly increase the gain to see what the cut-off is. Make sure you aren't dropping the ohmage too low on the amplifier. Check manual for correct wiring and such.

Protection mode


Disconnect all speaker wires from the speaker terminals of the amp. If it powers up and doesn't go into protect when you increase the settings, the wiring needs to be checked. If it still shuts down, the amp may need to be repaired.

Does it shut down or make loud noises when you move the RCA cables where they plug into the amplifier?

Amp blowing fuses


The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

Disconnect all of the speaker wires and signal cables from the amplifier.

 

If the amp still goes into protect when you power it up, the output transistors are likely shorted.
