i would be VERY CAREFUL if you are running any speaker below 4 ohms, you can blow the speaker's voice coil quite easily with a very small amount of distortion or DC current due to the low resistance, you could also, in some cases, cause the amp to overload and overheat too, i did that once with a power amp, and it's in the shop right now getting the output transistors replaced. so BE VERY WARY DUDE!
