Question about Lanzar VIBE286 Car Audio Amplifier
The amp turns on and starts to play then it stops and the protection led turns on. i replaced all my fuses and checked the wiring and it is still doing that
First try unhooking the speakers and see if it continues to go into protect mode. If it does'nt then your speakers are running to low of ohms required for that amp causing it to go into protect mode. If it still goes into protect mode check your ground, might have a voltage problem and check voltage going into amp. I have read the manual and this amp has advanced circuit protection. So if all I have asked you to do and it still goes into protect mode then amp is faulty and has some output transistors shorted or power supply mosfets shorted. Let me know what you find. But you need to do what I have explained to narrow the problem down. Good luck, Keep me informed. I will be glad to help you thru this. I also have a business of repairing car amps and you will not find anyone cheeper. So if you want it repaired and you feel you can't do it, just send it to me and I will repair. If you decide this E-mail me at:firstname.lastname@example.org and we can discuss it in more detail. Just a thought to try and help you out. I have many customers that send me there amps and I repair them and ship them back. A few come from this site. Let me know

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
