Posted on 2009-07-01

Is there a simple way (without resorting to using bulky inverters) that I can make a Bose SoundDock work on 12volts ?

The connector on the back has 4 pins and the transformer states 18v.

Any ideas ?

To go from 12v to 18v, you will need to convert to AC, go through a step-up transformer (transformers need AC), and convert to DC.  You can also build your own, if you are good with circuits:

Hmm.  The PSU says +18v 1A and -18v 1A.

I assume thats why there are four pins ?

If it's DC current, all you do is swap the two leads to go from positive to negative.  You don't need 4 wires to do that.

If it's truly a transformer then it's output is 18 VAC.

If it's a wall-wart you need to tell us if it's AC or DC.
