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.

I need the driver for it, i have no sound


Anonymous,
There are no drivers for the A425 speakers. Make sure the power cable is attached to the speakers as well as the speakers plugged into the correct jacks. If your speakers are plugged in and powered on and u still have no sound; check to make sure the sound card drivers are installed.
Thank You,

Dell a425 disassembly


I found this URL for you that shows a Dell forum where you could probably get all the info you need. It also has specifications for all the internals should you need to replace something. Good luck and be safe. I learned to hate capacitors a long time ago. :-) http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&l=en&s=gen&docid=DSN_E876EF53BCA3F058E030030ABD6260B2&isLegacy=true

A425 subwoofer, more bass? wires came off, no bass managment.


I wouldn't cross wires or leave one disconnected. Can you solder the wires back on the the control knob? Did you feel the subwoofer cone to see if it's working at all? I would guess the wire you didn't connect, is the subwoofer wire. Try putting it back to original cofiguration and solder the wires in place.

Can i hook a sub woofer up to m-audio av40s


odwalxo, you can't add a subwoofer because the only output you have on those m audio speakers is for the "other speaker of the set via regular speaker wires". Everything else it's just inputs.
