Can You Wire Speakers Through In-Wall Phone Lines?

Can You Wire Speakers Through In-Wall Phone Lines?

You aren't using your home's built-in phone lines, are you? Well, neither is most of America. But since it transports audio throughout the house in the form of your voice, could it do the same with music?

Well it turns out, you can. But it's not anywhere near as easy as it sounds.

Lifehacker reader Tom O'Brien (who must at least be a serious hobby electrician) has figured out a way:

Using existing telephone wire and powered speakers, it's fairly simple to connect speakers throughout the house via existing phone lines. This will work only if the lines have 3 extra wires, such as when no land line is in use, or if the house has 6 (very common) or 8 strand telephone wire. Cat 3 wire is 8 strand.

Yeah, we didn't understand it either. But basically, his plan uses the existing connections to wire up a source, his computer, to speakers throughout the house—without tearing down walls or running lose wires. It's "just a big complicated extension cable."
