Can Interconnects be converted to speaker cables

I would not advise doing this. Speaker cables require a much larger gauge conductor than is typically used in an interconnect cable.

Why would you want to do this?

Alexs is correct. Speaker cables typically carry at least 1000X as much current as a interconnect. Re purposing interconnects to speaker cables would be inadvisable in almost all cases.

Don't know why you'd want to. You'd be chewing up a perfectly good pair of interconnects in order to convert them to speaker cables. And besides, its really not quite the same. If you want to try it, then by all means do it. But there's a reason ICs are ICs and speaker cables are speakers cables.
