If I don't ask the stupid questions first, I always get burned! Have you tried removing both the +12V and remote connections from the amp and letting it sit for a few minutes? If the amp doesn't automatically reset (and you have removed the condition that caused it in the first place), your amp may need repair, as it might have shorted something internally.

How do i fix my Power Acoustik LT-980/2 car amp, it keeps on going into protect mode.


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 . .A thumbs up would be greatly appreciated if this answer is helpful to you

I have a brand new logic soundlab tx1002. it was hooked to a brand new radio and new speakers. When turned on, it is in protection mode. you get a popping sound from the speakers. we have checked all...


first disconnect one wire at a time, making sure the power is off. then connect power and check to see if your speakers are making the popping sound. when you do your speakers, make sure you disconnect both positive and negitive of each speaker at one time. when your amp goes out of protect mode you will have found your suspect wire. then trace to the issue. it could be as simple as crossed over possitive and negitive wires
cheers

No audio and staying in protect mode


You have no audio because it's in protect mode, could have a short in the speaker connections or one of the speakers - try it with speaker wires disconnected at the amp and also with a different pair of known good 16 ohm speakers. If the protect mode light doesn't go out then you may have cooked a driver and it will need to go to a shop.

Check the wiring at the speakers themselves. It's possible that while you were moving the box one of the speaker wires came loose and shorted against the other terminal. A shorted speaker wire or damaged speaker will cause the amplifier to go into protect mode. If you have a digital multimeter with a resistance feature, you can test the resistance between the positive and negative terminals for each speaker.
