My protect light is flashing from red to the green power light it makes a thud noise in the sub when it flashes i have checked my ground and power it all seems to be fine does any1 have a idea on what...


You either have a short in your wiring (between the amp and the sub) or have wired the sub(s) at too low of a resistance. If for example you have wired it to 2 ohms, when the amp can only support a 4ohm minimum, the protect light would come on once you tried to turn up the volume a bit. This may happen if you have lost the wiring off one of your subs or one of the voice coils, thereby affecting the total resistance.

Um the power light will flash then the protl. light will flash its all hooked up right but weird sounds coming out my subs.


Disconnect subs from output of amplifier and then turn on car and radio. Does amp stay on or go into protect? If it stays on then there is something wrong with the subs or how they are wired (series, parallel ) to the box and amp. If it still goes into protect then something internal with amp.

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.

Mtx 1000xd led light is flashing and the subs will not work


The light flashing usually means there is a short somewhere. Check your wires to make sure there are no slices and are touching. Also check to make sure you have your remote wire hooked up.

No Sound/ lights flashing on Amp


Disconnect your subs from the amp. If the lights go out then your sub is blown and is putting the amp into protect. If the lights keep flashing even with the subs disconnected than the Amp is toast.

Protect light flashing/ticking


this problem sound like you have too low of power going to your amp, test your battery and make sure its putting out enough power for at least the mininum amount of power that your amp requires, you can find that information in your manual or sometimes they post it on the amp itself. i hope this info helps
