Add/extend powered speaker wire for 2 Altec Lansing speakers

While trying to resituate the rear right and rear left powered speakers from Altec Lansing 5+1 powered speaker set (Model 251), it became evident that each speaker required an additional 2-3 ft of wire.

Each speaker's primary power source is clearly the subwoofer, though each speaker may also provide some sort of boost. The speaker system is connected to portable media devices, as well as to my computers.

Extending speaker wire and RCA cables is normally not a problem; however, the Altec Lansing design presents a unique challenge.

 The factory creates permanent (e.g., hard wires) connections between the speaker wire and the speaker and a single channel (e.g., mono), mini-RCA-style plug.

 The actual wire apparently looks and functions like a hybrid between single channel RCA cable and stereo cable. Specifically, the wire carries, like RCA connections, a single signal (e.g., left channel). However, the actual wire looks like very, very thin speaker wire.

After failing to find a solution at various computer and/or electronic hobby stores, (e.g., MicroCenter, Radio Shack), I visited Altec Lansing?s website. Unfortunately, a careful review of the site for documentation, troubleshooting strategies and/or related solutions offered no direction. And, an Altec Lansing customer service/tech explicitly refused to offer any solution or recommendation to this request for support.

I cannot be the only person who has had to extend powered speaker wire. Any suggestions?

Thanks
