Re: Protection Mode? amp wont start

With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

My amp just stopped working one day almost new dont known why

DID YOU CHECK YOUR FUSES? Is there anything lighting up on it to see if it is in fact turning on? If it's lighting up and there is no protection lights lit up then check your speakers to make sure you didn't burn them up. If there is a protect LED lit then unhook your speakers and see if it stays lit or not. If it stays lit then check to make sure you're getting enough voltage at the amp connection, minimum of 11.0 volts is required just to get it to turn on. If it has under voltage and over voltage protection LEDs see if they're lit. If you do all of these things and are getting enogh voltage, your speakers are not burnt, your protection LEDs are lit no matter what then you need warranty repair that amp. If your speaker wires are shorted it will make your amp shut down also, but since you were using it for a day or so my bet is that you burnt up one of your speaker voice coils and it's internally shorted and that will cause your amp to shut down in protect mode. Otherwise you probably internally fried your amp by too low of voltage or not enough current (amperage) due to not large enough conductor (too small gauge wire) should be minimum of 8 Ga. for each amp, 2 amps will require 4 Ga, 3 or more will need 2 Ga, or 0 Ga. wiring to keep the voltage and current flow high enough to keep from damaging the amps. Good Luck!

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. Using an ohm meter to the sub will confirm whether its bad or not. Invest in a cheap test set of 6.5" speakers.
.A thumbs up would be greatly appreciated if this answer is helpful to you.

I have a pioneer gm-d8400m the amp isnt working

flashing light could mean a few different things. 1- constant power may not be there. check with a test light or multimeter. should read around 12 volts. it would be a good idea to check all the power and ground leads. make sure u have a good ground. 2- bad sub. im assuming sub since its a monoblock amp. you can meter the subs. make sure the total ohm load is no less than 2 ohms. any lower the amp will go into protect mode. 3- bad amp. power supply may be bad. the newer pioneer amps are full of protection circuits. ive been a professional installer for a shop about 8 years and we sell pioneer. hope it helps.

Mrv F345 power cut out and now the screen flashes blue

disconnect all of the speaker wires at the amp and turn your system on -if the amp stays on then you likely have a roasted coil in one of your speakers somewhere and causing a short which is shutting your amp down into protection mode-if the amp wont stay on with nothing connected to it then you have probably roasted something inside the amp and uhhh good luck bro

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.

Amp staying in protection mode

No, this amp is not a heavy power consumer- matter of fact it takes very little power to run.Maybe you should check the fuses on the amp to see if they are what is recommended.Also check your fuse kit to your amp- your fuse might not be big enough.If neither works take it back where u got it.
