Default Pinout of Bose Stereo Computer Speaker Volume Remote

Hi,

I recently got a pair of stereo Bose computer speakers out of the dumpster. I got 2 speakers and a volume remote. (A unit that connected to the woofer and has a big volume knob.) I didn't get the woofer (which contains the amp and everything) though.

I'm really new to audio stuff so I figured I'd build a simple amp so I can use these speakers. Except I want to use the volume remote too.

Here is the following information I've managed to collect on the pinout of the volume remote. I suppose the color of the wire is unimportant but maybe one of you has taken apart Bose stuff before.

Wire - Description
---
Black - Ground
Red - 12Vdc
White - Unknown, connected to an IC (QT113-16 capacitive sensor?)
Grey - Unknown, appears to be unconnected
Violet - Left Audio out
Orange - Right Audio out
Yellow - Unknown, sounds like woofer audio out.
Blue - Shielded wire, unknown
Green - Shielded wire, unknown

Violet, Orange, Yellow, Blue and Green are all at about 12Vdc offset which surprised me. I figured most of the time ground is used as the common connection. So audio out is across Violet/Orange <-> Red.

By process of elimination I think the shielded Blue/Green wires are line in. However, they are at a 12Vdc offset so how do I connect my audio player?

Any help and any corrections/advice are appreciated. I'm basically just starting out with audio/electronics. Thanks.
