Hii. I made a new amplifier at home. But now i have a problem. When i turn on or off the amplifier, at the output for the speakers a huge spike of voltage is created and the speaker makes a lot of vibrations which had already ripped my speaker. Actually the problem comes before the amplifier, from a circuit for microphone input. Now i want to ask how can i protect my speakers. Is there any type of circuit to put on the output or the input of the amplifier to limit that voltage spike.
