Dell (Altec Lansing) A425 Subwoofer Pinouts
This is a standard female DB-9 serial port.
Here are the pinouts.
Pin 1 = Left Speaker Out +
Pin 2 = Left Speaker Out - (Common Ground)
Pin 3 = Left Line In +
Pin 4 = Right Line In +
Pin 5 = Left/Right line In - (Common Ground)
Pin 6 = Right Speaker Out +
Pin 7 = Right Speaker Out - (Common Ground)
Pin 8 = Power A
Pin 9 = Power B
Jumper (short) Power A to B to turn on.
If you want a volume control you need to put one on the inputs. You will buy buy a stereo volume control or potentiometer.
Here is some info on how to do this.

Ironically enough, I went on here because I have the satellites but no subwoofer! LOL, what are the odds. Anyways, if you happen to receive this information, can you please email me at email@example.com?
Like I said, I'm searching for the same exact information for a similar problem and this would REALLY help as I can't power the speakers without this.

All I wanted was a pinout diagram for the male plug so that I could wire up a new plug. Did not want to have to re-mortgage the house to get that. Thought such info would be free.
Anyway have stripped away all the plastic moulding to reveal the connections so am OK now Thanks

worked on this for 3 days but i finaly got it I had to open it an follow coper lines using datasheet, the connector is RS232 the pins are
1 = LED+
2 = IN R
3 = OUT R
4 = OUT L
5 = GND
6 = ON
7 = 5V
8 = GND
9 = IN L
so you have to put a swiths between pin 6 and 7
you should also put a potentiometer GND-IN-(AUDIO SOURCE)
and a led between pin 1 and GND
and that is it!
