Hey Fellas, I have some speaker crackle issues on my stereo. Even when the volume is completely down to zero, one just keeps on cracking. So, what are my options?

There are so many things which can cause this, I think it is best to first figure out where the problem lies.
Try plugging the speakers into another system. If the problem remains then it is in the speaker connector(s), cables or in the speaker boxes - wiring, crossover or the electromechanical speakers themselves.
If you don't have another system available, just reverse the speakers. Does that crackle switch to the other side at the lowest volume level? If so, then you can eliminate the speakers.
If not, see above.
Is the equipment showing this problem with all signal inputs (CD, DVD, Tuner, MP3, etc.)?
Are the controls analogue or digital? If analogue, try cleaning the volume controls with an appropriate cleaner (Radio Shack).
If digital or the cleaning doesn't help, then you need to check for loose connectors in the equipment. Careful, audio electronics frequently uses mosfets and other components which are very sensitive to static electricity.
Speaking of which - has anything in the area changed? Does the equipment still crackle on another branch circuit? In another room?
If you can track things down to one specific element or component, we can probably help fix it.
Generally speaking, vacuum tube equipment is always worth repairing. Solid state only if it is audiophile quality or has sentimental value.
Most crackle, sizzle and pop comes from dirty controls. Bad shielding is the next most common cause, at least around here in a big city. I had to buy high quality isolation transformers and go to optical leads to work around my ham-radio neighbor a few years back. But even a light dimmer which is fixing to go can cause surprising noise.

Hey Kevin, I guess I should have clarified, see the "Attn: Record nuts, see my new addition" post
ok
Gosh that's pretty. I think folks have covered most of the possible problems by now; my two suggestions are on the other thread.

I found a product called "De-Ox-it" works best. Spray it inside the little hole on the backside of the control. Exercise the control several times. Wait 10 minutes and repeat. The crackle should now be gone.
