Protection Light Is Coming On

When I plug in my Rca connections, the protection light comes on. I have the speaker wires hooked up to the amp, but no the subs. The only things connected are the power and the Rca connections. However, the protection light only comes on after I hook up the Rca. This problems arose suddenly and I do not know what the issue is. I am not very familiar with car audio, so if someone could help me out, that would be fantastic. Also, my younger brother has told me that I may have loose connections at the head unit, because the left side of my car likes to go out randomly. Are these two issues connected?

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

The saftey red light keeps coming on

It means that the subwoofer is blown. The red light is called the Protect light. Disconnect the speaker wire from the amp and then turn the amp on and see if the red light goes away. But if as soon as you hook the speaker wires back to the amp and the red light turns on that DEFINATELY means the sub is blown.

Your amp could be in protection mode! Sometimes turning up to high or wires touching will put in protection mode! It will have to be unplugged for a day or two to drain all power out of the memory. Leave accessorie/ignition wire hooked up, just not power and ground wiring. It should reset itself.

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).

Sony explode amp for my car

Try disconnecting everything but the power connections. If the protection light still comes on, then there's a problem in the amp. If it goes out, then there's a problem elsewhere. In that case, hook up one speaker cable at a time and power on. If the protection light comes on, then either that speaker is bad, or you've got too many speakers connected to that one amp output. Too many speakers connected together can cause an overload and trigger the protection circuitry, or worse, blow out something out.

Hope this helps, and please rate my advice.
Thank you, and good luck!!

Protection Light irritation

If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.
