i have a 4-year old aiwa mini component system with a 2 speaker out (2-wire, L & R), 2 surround output (rca), and 1 superwoofer output. my problem is the original speakers which connects to all of these connectors were badly damage that it becomes unusable. Now the surround output has an impedance of 16 ohms and I can't seem to find any speaker that match this rating. Also, if ever i would find one, how do i connect a 2-wire speaker to rca? I don't know how to connect the positive and negative terminal of the speaker to the rca. Is this confusing? Any inputs would be greatly appreciated. Thanks.
