SOURCE: Amp keeps turning itself down - cant turn off 'protection'

yes,pls.stop plugging the system,you may harm your system if you do so,the system has it's own system analysis mode,and if there's something wrong in the circuitry,it will activate,you need the authorize service center my friend,it's a technical problem.

SOURCE: Amp protection light comes on when raising volume...

It sounds like you either have too low of an ohm load or the voltage is dropping at the amplifier's power terminal.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.


If the voltage remains near or above 12v, disconnect one speaker and see if it shuts down. If it doesn't, disconnect that speaker and connect the other speaker. If it only shuts down with both speakers connected and the voltage is staying above 12v, the ohm load is probably too low and you'll need to rewire the speakers.

SOURCE: my amp is on but the protection light stay's on!!

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.

SOURCE: When powered on protection light comes on

Protection usually means that there is a short some where. If it is inside the amp or external I couldn't tell you. You could check the fuse to make sure that isn't blown. I had a Memphis amp that blew both fuses and the protection light came on. I swapped out the fuses and worked fine, still works. If you have a multimeter set it to OHMs and check the resistance between the power terminals. It should be very high. If these things don't work then there is most likely something wrong with the amp or your power termination. I wasn't able to find a lot of information on this amp but if it has screw type terminals, did you use terminals. If you just put the wires in the terminals make sure there wasn't loose strands touching. I hope you can get this one.

Disconnect all the wires except the three main power wires, ground, 12v battery and remote. Now, turn on your radio, if the protect light is still on then there's an internal short in the amp. If the light turns green, then there's a short in either the auxiliary cables or the speaker outs. If it turns green, then troubleshoot the other wires that plug into the amp by connecting them one at a time until the protect light comes on, which will tell you that there's a problem with that speaker/aux wire.

What does it mean when the red protection light illuminates


Hi the protection light comes on when there is a problem within the amps. circuitry. Generally speaking the protection light normally comes on when powered up while the amp checks all of its voltage rails so that they all lie within a specific tolerance, when all have been verified to be in spec. then the protect light goes out & the power light comes on. If the protect light stays on then a fault exists within it's circuitry. Cheers, acbva.

VR3 Amp Protection Light problem


Looks like you have covered all the basics.

The remote wire is the switch that turns the amp on and off. So you are probably just killing the power to the amp.

Sounds like a short in the amp itself if all the input and output wires are disconnected and the protection is still coming on.

Protection Light Comes on


Sounds like you have an ohm problem, Tryy hooking the positive from one speaker to the negative on the other speaker. Then hook the negative from the first speaker to the negative on your amp and the positive from the second to the positive on the amp this will drop your ohm load and the amp should stop going into protection.
