Default audio over mains supply?

Just thinking about how to set up wireless rear speakers.

Is there a simply/cheap way to send audio over the mains circuit.

I could then build 2 separate active rear speakers. I would want 2 channels, and each speaker to be fully independent. ( I have a mains socket in each of my rear corners)

Dare I say it, the quality does not need to be great, it's only movie sound effects after all.

You would only be able to send a mono signal. Also it's now illegal to knowingly superimpose signals or interference on the mains. Well maybe not illegal but not inline with CE regulations.

Or buy the two channels of wireless needed.
Try doing it with CAT5 in the wall = wired.

I could accept mono, and CE regs don't effect me, so I'm not put off yet.

On the CE thing, I thought you can buy LAN over mains set-ups.

Could you expand on this? what are you suggesting I buy?

I suppose the cheapest solution I've got so far is to buy 2x 'video senders' at about 30 each.

You are still going to need a mains lead to the the speakers if they are wireless. Why not just use thin figure-8 or flat cable and put it under the carpet?

That's what I've got at the moment, but new carpets are being fitted soon and I was thinking it would be nice to avoid having to install the wires under the carpet.

But it was a bad idea, especially to end up with an inferior and more complicated system.

Radio Shack Accurian amp - the receiver/25 W amp is still available at a few stores for $15

I don't know if the "HomePlug" transmitter can be found anywhere though

that's so cheap, but maybe it was a bit more expensive before the transmitters sold out
