I told a guy on accident that I had 2 fifteen THOUSAND watt amp and he said, ****, thats a lot of power.
I told him that I needed 200 ft of 1/0 and he said, ****, thats a lot of wire. I then proceeded to tell him that I was running power and ground from the battery. To which he replied you know that will fry your alternator. He said I should be ok with one run and a gold plated distribution block.
Oh this was the guy at the local audio shop by the way.
