Help with M-Audio LX4 5.1 speaker noise

[thezfunk]

Hi guys,

I am not sure if this is the correct forum section for this question. I am not sure if this is the right forum, period for my question. If there is somewhere more appropriate please refer me.

I have an M-Audio LX4 5.1 setup on my computer. I have periodic crackling/popping/bursts of static from the front right speaker. I have changed speakers and the inputs from the computer and the problem remains with the front right channel. I am pretty confident the problem lies with the built in amp in the sub. Could this be a bad capacitor or op amp? What should be my process for narrowing down the bad component and replacing it? A schematic for the amp would be helpful if someone knows where to get that. Anyone else have this issue with this setup?

Probably poor soldering somewhere. Yes it can have something to do with an opamp - a bad joint in the feedback path can sound really ugly.
