    I've come to the conclusion that my ground wire (which was installed w/ a previouse amp) had lost good contact with the chassis, reseated the ground, and cleaned the contacts. amp works fine now. thanks for the input pbabin

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connectes to the vehicle) 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.

Do this with no RCA or speaker wires connected. Let me know what you find.

Power acoustik bafm2000/1d no power coming from channel

HelloAny one channel circuit of the amplifier has any sort of trouble, the amp will go to protect mode. It may be a direct short in it he output circuit. This is the common fault for these type of amps. A through check should be done to find out the reason. You must have sound knoledge in electronics, and experience to do this work by yourself. In most cases, unlike TVs, amps circuits are quite complicated and user cannot do it by themselves. OK.

50 volt regulator

Most techs offer a warranty. Contact him and ask him if he will look at it again and ask him if he's going to charge you to troubleshoot it. If its the same problem and it's not a problem caused by incorrect installation, shorted speakers, shorted speaker wires or an incorrect ohm load, he'll probably warranty it.

The main thing is to be polite. If you are rude or accuse him of ripping you off, you can be pretty sure that you'll have to pay to have it repaired again.

Let me know if you have any other questions.

Lanzar Vibe 1200D protection light

You will need to show it to a service technician as it seems the output section has blown so it remains in protect mode. One reason (could be) that the input to the amp was high and may have been clipping for some time before the amp decided it could take it no more

Amp stuck in protection mode.

check to make sure your ground wire is attached to a clean metal surface no more then 18" away from amp. check all wires to ensure none are touching other terminal. all else fails remove one sub and see how it play, if its works great switch subs. could be a defective amp. if it is the amp and you payed for it with a credit card or bank card you can do a charge back from the bank to get your money back if the store wont replace it. thell the bank "you want to do a charge back cause it wasnt as discribed).

My amp quit working

ok I thought I anwered this one but first thing to try is disconnect all your speakers and see if the light goes out if it doesnt then your gonna need a schematic and a working know how on solid state amplifiers. first check al the outputs for the speakers for dc If theres dc on an output then that output device is shorted or leaky. Ive have open drivers as well as current control transistors leaky or shorted to that made the protection come on.. Good Luck
