My MTX 600xd amp light won't even come on. ... Red light comes on. ... one.. and some times it goes into protection... once I turn the car off...
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
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.
Either blown subs, or bad amp.. Disconnect the subs, and try turning the amp on, if the amp is still in protect then your amp is bad, if the protect light goes off, then your subs are bad, or possibly wired at to low of an impedance, but I don't think that will trigger the protect on an Audiobahn amp.
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?
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.
In virtually all instances where the protection light is illuminated, the amplifier has gone into protection because the output transistors are shorted. To eliminate external wiring problems do the following.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.
If it does have blown outputs, it's is likely due to the speaker wires shorting together when the woofer was out of the vehicle.
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.
