I've got a Stewart World 1.2 power amp coming which I will use bridged mono into a single Acme B-2. Two questions about speaker cable to run from amp to cab (this is my first power amp & cab setup): 1) Any minimum wire gauge I should stick to? I figure 14 gauge is good enough, but would 12 gauge make a difference? Or is even 16 gauge OK? 2) Any brand recommendations? I'm willing to pay the $30-40 for a Planet Waves or Monster cable if I actually get some benefit over a basic cable.
