Is the red light that says protection on the hifonics hifi1001.1d suppose to be on or of? My is not on is that bad

My guess is if there is a fault and it has to go into protect mode the light will come on. The red color is usually stop or warning etc ... green = go or good.

I have a dual electronics 4 channel amp that goes into protect mode as soon as i throw power to it

unplug all the speaker from amp then power on. if you still have a protect light amp is bad and if you have no protect light continue to hook up each speaker one by one while amp is on till you get a protection light and that speaker would be the source of your problem

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 . Send to Rockford Fosgate for repair .A thumbs up would be greatly appreciated if this answer is helpful to you. protect-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

What does it mean when the red protection light illuminates

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.

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?

Mac-505 amp

Disconnect all speaker wires and signal cables from the amp. If it powers up normally (no protect light), the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.
