Re: hi i am matt
If the protection LED lights only after the remote voltage is applied (head unit is switched on), the amplifier likely has shorted output transistors. If the protection LED remains lit without remote voltage applied, the amp may have other problems.
Does the protection LED light with no speaker wires connected to the amp and no RCAs plugged into the amp?

Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?
When ever the amp stays in RED protection mode with out any speakers hooked up to it, YOUR amp has internal damage some where. Can't tell you how much to fix, Could be cheap or not worth it. Talk to your local electronic repair, would be a good start.
Hi the protection light comes on when there is a problem within the amps. circuitry. Generally speaking the protection light normally comes on when powered up while the amp checks all of its voltage rails so that they all lie within a specific tolerance, when all have been verified to be in spec. then the protect light goes out & the power light comes on. If the protect light stays on then a fault exists within it's circuitry. Cheers, acbva.
Outputs are fried. Try disconnecting your speakers and see if it still goes into protection mode. If it does then you
A thumbs up would be greatly appreciated if answer is helpful for your question. THANK you and GOD BLESS
are you sure its not PROT?
the amplifier is protecting itself from fire because of something.
Disconnect the subs. and turn on.
if it comes on normally, the subs are at fault and will need attention. If the light still stays on, you hafe probably blown an output on the amplifier and it will need repair.
First off, according to the manual, the protect light should be green. That's normal operation. If it is red, that's a problem.
If it does go red, disconnect all of the wiring to the amp except the +12V and ground. Short the remote connection to the +12V to force the amp on. If the protect light still lights red, the issue is inside the amp and will need repair. If the issue goes away, try reconnecting one wire at a time until the protect light goes red again.
This is not a ovehaul light. It is called the protect indicator. It kicks in when the amp detects a fault on it's output. Disconnect the speaker / sub. Power up the amp and see if the light goes out. If it does you Sub is toast and needs to be replaced. If it stays on then the amp is done.
