Thank you very much, it was very helpful!
I have now set it up, and as I said, I knew some of them weren't working. But now it seems all of them are blown or whatever it's called, and scratches ALOT or doesn't work at all.
I tried to connect the amp to my mothers speakers that should work fine, and they scratched too.
Do you think that it's me connecting it wrong, the speakers or the amps thats broken?
