"To say wire gauge does nothing for you is just proof someone knows nothing of electricity."

im not saying upgrading will do nothing, just not a whole lot. for an anmp that size, the difference in 8 AWG and 4 AWG is negligable.

as far as brands go, thats going to make less difference. the "skin size" (or surface area of the conductive portion of the wire) of both will be almost unmeasurably close, so the main difference will be flexability/resistence to tearing/etc.
