I have a few questions regarding ohms. I have a 4 ohm 300 watt amp head, and I need a cabinet. I know for sure i'm going to get an Avatar 2x12 cabinet, but I don't know wether to get it in 4 or 8 ohms. I might want to get a 2x10 extension cabinet, but then again I might not. I'd like to try to keep my options open, but I've heard that 8 ohms doesn't make as much noise as 4. Is this true? What do you think I should do?
