I have a Harman/Kardon SoundSticks II subwoofer without any satellites (L & R), so I don’t have a volume control for it. I’ve had some luck with jumping two pins on the right speaker connector and connecting two speakers to the left speaker RCA jack. I would need some sort of wiring diagram or service manual If I want to figure out how to wire up the right channel (I want to use the system in stereo) without the volume control.

I found this useful pinout on Nick Brook’s site:

The R speakers are driven between pins 1 and 2 of the s-video 4 pin connector (the two furthest-apart ones, at the bottom, white and translucent in the cable). Pins 3 and 4 connect to the touch-sensitive pads on the R speaker for volume down (3) and volume up (4); you should be able to control the speaker volume by simply touching a bare wire connected to these pins with your finger (I think it detects mains hum or something). Note: Touching both volume controls at once puts the system into “mute” mode, which can make the system appear not to work. Simply touch volume up again to unmute.
As you have found, the L speaker is simply driven between the two connectors of the RCA plug.
The original satellite speakers consist of four 8 ohm drivers in parallel, so the amp is expecting a 2 ohm load.

If you’re intending to use just the sub with no left/right speakers, the control pin jumping from the diagram will only work if you bridge the -/+ wires of each speaker connection - it must require the speakers be “connected” to operate. I simply connected them to each other to complete the series and provide signal feedback. Once both are connected the volume control pins work perfectly.
