My receiever has an RCA jack for the sub woofer. While this works great, I am limited to keeping the sub-woofer near the receiver.

My living room is wired with speaker wire from wall to wall, and I have 4 unused banana jack plugs available.

I'd like to somehow convert the RCA plug to send the subwoofer signal over one or more of the speaker wires, and then convert that signal back to a RCA plug to input into my sub-woofer.

Does anyone have a suggestion on how to do this?

Remeber that this subwoofer signal is really low power ... in general "in wall" speaker cable is not that high quality so I think you will pollute your sub-signal quite alot ...

You can easily try this, just make/buy a RCA-> banana jack piece on both ends...there is no "conversion" needed in any way.


PS : I wonder is any standalone WIRELESS solution exist for this, the sub/LFE output on the receiver is put into the transmitter and on the sub you have the receiver wich converts the wireless back to a low-level wired signal that you can put into the sub.
Then you can shovel you sub around and only need 1 power-plug.
(I'm sure it exists, vendors like Philips / Samsung have WiFi/bluetooth-based, digital connections from receiver to back surround speakers)

Kal,

Unless I'm missing something, the specs on the data sheets appear to only go down to 100hz, not sure that would really work for sub applications? I do like the idea though for testing various sub placements without all the wires. :)

Does anyone have a suggestion on how to do this?You can do it by simply soldering RCA ends to each end of a 2-stranded speaker wire. It MAY work fine. IT MAY not. Subwoofer cable is shielded and bare speaker wire carrying a pre-amp level signal can be susceptible to interference, especially over a long run. But it is probably worth a try as it is simple enough to do.

Otherwise, any chance you can pull some RG6 (or RG59=less stiff) using the existing speaker wire? If not, have you considered running the sub's cable traditionally instead of in-wall? There is some "ultra-thin coax" available that is really, really thin and can easily be pushed under the baseboard if you have carpet. Simply screw on some F-to RCA ends and you're done. If it's not long enough, you can use F-to-F to connect 2 or more strands. Works great for subwoofer runs.
