I suspect that your speakers turn on after power is cut to the middle momemtary switch.  What that means is that you need to let power flow first with the switch in an closed state, THEN press the switch to open it and trigger the speakers to turn on.  Otherwise, the speakers just get a closed switch when the speakers are turned on, which triggers nothing.

You could try the peale cap turnon trick, or a variant on it, which Blanka suggested earlier.  You would need to bridge to two contacts of the middle switch with the capacitor.  Note that polarity is important with electrolytic caps.

What the cap will do is allow current to flow (closed state) until it is fully charged (a second or two, I guess).  Once fully charge, caps become open-state and won't pass current.  So, you effectively create a delayed switch-press, which is what we want.

Without having your speakers in front of me, I can't be sure or exactly which terminals need to be crossed by the capacitor, but I think that the cap trick is possibly the solution for your problems.  You'll need to solder ...

I tested the vertical pairs and it seems that the 2 on the far sides are normally open, while the 2 in the middle produced higher ohms (around 5 or 6 megaohms) when the button was not pressed and low ohms or no ohms when it was pressed. I tried various combinations of the 6 with the leads and got ohms for the most part I believe when the ones on the side were linked with the ones in the middle.

Does this mean just causing a short between the middle ones will cause it to always stay on when connected to power?

Thanks for the help everyone.
