Wire connection is not right or the power source is not enough. Make sure the radio wires connected to the car are correct and that the usually blue and white REM wire from the radio is connected to the REM position in amp. Power source must be straight from battery not from anywhere else. Ground wire should be connected any metal bolt in trunk or to a new hole drilled into frame. Also make sure that the wires for speakers are running on 1 side of the car and the power is on the other side, never together on same side of car. Hope this helps.

My amp has a protection light on need to know how to fix. When I pull the fuses out the power comes in but when I put the fuse back in the protection light comes back on


From the description your audio output transistors or ic's have a short causing a load problem activating the protection circuit. Turn volume right down, power off, remove speaker wires from the back, power on! if protection kicks on it is the audio outputs in the receiver, if not! check speaker wires for shorts, hook back one at a time until defective wire or speaker is located. The audio outputs will need to be addressed by a technician since there is complexity involved.

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.

I have an older red sony xplod 500w 4ch amp. the power/protection light is glowing red. what does that mean and how do i fix it? I have no sound.


The protection light comes on if the amp overheats or if the speaker outputs are shorted.

Turn everything off and check all of your speaker wires for shorts. When you locate and repair the short, the protection light should go out and your amp will work normally again.

Hope this helps!

PROTECTION LIGHT


Disconnect the speaker wires and the RCA cables from the amp. If the protection light still comes on, the output transistors have likely failed.
