Hey there, Relativly new to home theater. Purchased a well-rated HTIB system for my parents. Problem is, the included speaker wire is too short to reach the rear speakers (I have to thread the wire to them in a round-about way). Simple solution is purchasing a spool of speaker wire from a local retailer and cutting to length. Problem is, I dont know what to do with the tips. I've been told bare copper wire will corrode rather quickly. However, the standard speaker wires seem to be made of an alloy, perhaps of silver. They don't have any proprietary connection scheme...it just seems to be twisted, exposed wire at the ends that are loaded into the "spring clip" style terminals on the speakers. So, what's the recommended solution? Is there a wire I can get that will not corrode if the tips are just left bare and fed into the speakers? If not, are there connections that will attach to the speaker-wire and will also go into the spring-clip backs of the speakers? thanks for your time.
