I am installing a 70w per channel amp in my upgrades to my car sound. I am
not a nut, I just like a good car stereo....

What would a quality car stereo shop use for speaker wire ? I am thinking
of 16 gauge. Is that sufficient for this purpose (70w per channel).

I don't want to start a war here about Monster Cable and stuff like that, I
just want practical advice on what makes sense for the proper gauge wire for
this installation.

Thank you !

James
