Hi, I dont really understand the 'Ohm' thing and I think I have just cocked up when buying some stuff that I thought was a bargain but we'll see. I'm pretty new to the home cinema thing, had an out of the box thing before and that was easy, but now I've bought myself a PS3 I thought I'd go the whole hog and get a surround amp. Marantz SR4300 AV Receiver, ebay, £80 thank you very much. Hmmm, speakers, Mission M70 x4 + MiC7 centre, no sub, ebay £51 thank you very very much. This is my problem, the amp says 6 Ohm speakers, the speakers are 8 Ohms, what happens if I use them for any length of time? I only noticed the 6 ohms thing on the back of the amp when I was about to plug them in. I had already tested the amp with some old Pioneer speakers from my old hifi to see if it worked and they sounded ok to me. Listened to the radio for an hour or two without any explosions. Can somebody try and explain the 'Ohm thing' to me, I'm not an idiot, I'm pretty good at building PC's but this has me stumped. Any help will be much appreciated.
