i have a question about some speakers and a stereo. i have an old stereo receiver and cd player that i've been using with some speakers for a while, and they're awesome. when i get the basement to myself i'm gonna wire it and put a shitload of speakers everywhere. the thing is , some of the speakers i have that i'm gonna use have an impedance(SP?) of 4 ohms, and on the back of the stereo it says that they need 8 ohms, so my question is if i hook the speakers up anyway would they break or something, or will it be ok?
