Oh dear! Protection system has detected a short in the main power amp. The water has caused a great deal of damage. You will have to replace all the parts that have been damaged. Your nose will lead you to where to look.
The protection light is on indicating a short or over- voltage problem. If you disconnect the speaker leads and the light goes off or green then the problem is a shorted speaker or wiring problem. If the light stays red the problem is inside the amp and it will need service and parts.
What kind of amplifier do you have? Does your amplifier still work? If so, it could just be the red light that tells you your amplifier is being protected
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.
Does the amplifier do this when you don't have the sub hooked to it? If so, you have a pinch/short in your ground or power wire. If not, the subwoofer has a short in its voice coil or the amplifier needs to be repaired as it cannot handle a typical load.
If the protection light is on, the amplifier likely has shorted output transistors. To eliminate other possible causes, read through the following page.
