I have a kicker 500.2 red protection light is on and red light on top of amp flashes every couple seconds. Have checked all connections and other amp in truck works good. I bought two of these amps and...

Disconnect all the wires except the three main power wires, ground, 12v battery and remote. Now, turn on your radio, if the protect light is still on then there's an internal short in the amp. If the light turns green, then there's a short in either the auxiliary cables or the speaker outs. If it turns green, then troubleshoot the other wires that plug into the amp by connecting them one at a time until the protect light comes on, which will tell you that there's a problem with that speaker/aux wire.

I have my amp hooked up right to two 12 inch subs but the red protect light comes on wht does this mean?

Check all your cable work.
Power is connected tight? Ground is attached tight - on both ends (my guess is it is the ground) Remote cable?
Is the ground a proper ground?

The red protect light is coming on

It is possible that your amp is going over the threshold limit of draining current to give out the protect signal. What could be done is to first checkout if your speakers are loading the amplifier, check the rating of the speakers and the impedance, must not be too low.below 2 ohms. Now check the source signal if this is bringing in any transcient signals to power out the outputs particularily high/low freq. So decrease off your bass and treble to mid position and test again. see if there is any improvement, if so there could be a filter problem with your set. Connect an external source and see if the amp powers better , in such case check for fault in cables, input lines and ground with in the set. Repeat this and check. Hope this helps you out. Good day

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.

!!!red protect light is on!!!

Hello beaugarcia26,

Unless the amp itself is defective, there's a short or ground somewhere.

First disconnect the speaker wires and RCA (or high level) inputs, leaving just ground, remote turn-on and power leads connected. Then see if the amp powers up normally. If it doesn't check the ground with a multimeter and make sure it is good. If the amp powers up normally, check the speaker, speaker wires and inputs for shorts or grounds.

Hope this helps.

My amp stays in protection mode

Does it go into protect in the vehicle if you disconnect the speaker wires from the speaker terminals of the amp?

Legacy 1470 smoke prob.

If it begins to smoke with only the B+, ground and remote connected, the power supply transistors have likely failed.

The protection light generally won't come on if the power supply is blown because the supply must be working for the protection circuit (which protects the output transistors) to engage.

The power light may be connected to the B+ side of the power supply. If that's the case, the power light will illuminate even if the amp is inoperative.

Let me know if you have any other questions.
