Grounding cable gauge size

A copper grounding rod can prove rather effective.

Always keep an open mind and experiment. You will not only improve your listening pleasure but also have fun on the journey.

Please help me to understand, I'm curious to try this speaker grounding tweak since my speaker cables go directly into a floor hole and are suspended in the rafters of my basement.

So I can run a wire from the black '--' speaker terminal to either the copper water pipes below (the panel box ground runs directly to an outside copper ground rod) or since it would be easy to drive a grounding rod underneath the speakers this is prefered? I can also easily do this at the amp '-' and compare the two spots and the two grounding strategies..

Thanks much.

I have my speaker's negative terminal grounded into one of my DIY grounding boxes. If anyone is interested, I can share the ingredients. And perhaps some pictures on my systems page. 

Others with more experience in this type of grounding can answer.

I would not connect your negative terminal to anything electrical ground (which would include a copper pipe in many homes). You will have a ground loop and it will be unpleasant for your gear. 

Proceed with caution.

Ozzy, is anything else connected to the box, or just the one speaker negative to one box that is its own terminus?
