actually the trigger is < 2.5 v

I'm in your same Situation. What I've found out is that the 2500 are very sensitive to voltage input. I was trying to hook up a 5 volt through USB, but it didn't work well. I am now using 2 D Batteries with 3.2 volts and it works great. I ordered a 3 volt power supply from china and will be hooking that up to a switch and then to my speakers. You should be able to get a diagram of the pins. Since you are not using the data link pins 6 and 7 are not used. You must hook the + power to pin 4 which is the speaker turn on. The - neg of the power supply has to be grounded and the only way I have figured it out is to connect it to pin 2. Pin 2 is the neg for the speaker leads. The right speaker is pin 5 the left is pin 3. Right now I'm having problems with have my speakers in stereo. I think they are only MONO. This will at least get you to be able to power your speakers and hear them. Make sure you get a pin diagram. The pins are not in numerical order. I cut a B&O 5 pin speaker link cord in half and connected it to a 1/4 jack. The other problem is the input volume. You might need a line driver to get the volume out of the speakers you need. I think you could also use a voltage step down from 5v to 3v if you wanted to use a computer USB as a trigger. That's my next idea. Let me know if this helps or anyone that has an exact schematic on this cord.
