I'm thinking we do have country specific components!
Your small gague speaker cable will show little resistance with no load on it.
Put 100Wrms through it & it will fail dismally - compared to the larger gague Monster Cable.
I have just bought some Hertz Energy components (ET20 tweeters & EM100 mid's) along with a custom made crossover.
I'll put up some install pic's when they arrive.
