You just cant pick a random pot. The problem you have is called impedance. You need to know what the impedance of the speaker is. 4, 8, 16 ohms This part is an L-pad, Where the L-pads resistance has to match the speakers. There are also T-pads, Basically, the pad keeps the impedance constant value. so in an L-pad, there are two pots wired together like the letter L, so while one pot goes up the other goes down. if you want a more detailed explanation go to the wiki
please pin NC in my speaker do you know what??
because i don´t use it but when i worked without potentiometer and i don´t connect this pin all works well and i listen music
