What does my protection light come on after hooking everything up


There is something shorting out the amp. What you will need to do is disconect all wires and hook up one at a time. Connect ground, !2 volt and remote see if amp turns on ok. If it does try connecting each speaker seperately to see if either one sends the amp into protect mode. Then connect the rca. See what causes the amp to go into protect mode.

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
system.

Havin problem with a1200 class a/b amp it ligts green and red at same time after hooking in remote how doi fixdo i need diagram to fix


Make sure you don't have any shorts on your speaker wires or rca cables. Unplug one at a time, the turn on power until it stays green with no protect light, then you know what input is causing the short. If you remove all speaker wires and rca wires and all you have connected is the ground, power(12volts) and remote and it still lights up red/green(in protect mode) then your problem is the amp.

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.

It appears that the amp is going into protect mode. To eliminate external causes, read through the following page. Let me know if you have any other questions.

Protection light grief


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. Vibe is mediocre. Time to invest in an old school Lanzar Opti Drive amp. .A thumbs up would be greatly appreciated if this answer is helpful to you. protection-light-grief-shonxoarcym4awy4zl1imx4o-2-0.jpg

Protection Light Is Coming On


You say the protection mode only occurs when you plug the RCA's in. Does it have to be both RCAs or just one?

The other end of the RCA cable is plugged into the HU?

It possible the RCAs have too much DC voltage on them, causing the amp to go into protection.

Is there a short in the RCA cable?

I would definitely check out the RCA connection at the back of the HU, as it sounds like there could be other issues there. Make sure the RCA connectors aren't touching any other metal (especially +12V).

Amp blowing fuses


The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).
