Speaker hack and electrical pass-through questions

<< < (3/4) > >>

NickG:
In the end, it may be that simple.  There is an ohmmeter setting on most multimeters   Imagine your multimeter leads as a switch.  When the leads are touching, it is closed (pushed)  When they are not touching, it is open.  Now touch the leads to the switch contacts instead of to each other.  If they are normally open contacts, then they should have continuity when the button is pressed:
On most ohmmeters(Ω) continuity reads as a low resistance; zero ohms or something very close like 0.03 ohms.
You may need to ensure that the PCB is disconnected from the sub-woofer unit if you take these measurements or you may read back across the board in it.

It is a flip-flop like circuit that needs a pulse to get in the prefered state. Same as computer-power-switches.
Seeing the board, it must be not difficult to bypass it, but I need the scheme to help you with that. You can also try the capacitor hack for computers:

if you unplug the speakers, hold the button down, then plug them back in, while keeping the button held down, do the speakers stay on?  if so, you technically wouldn't need to solder anything, you could used a zip tie or something similar to go around the board and hold the button down for your.    if not, then you will have to listen to one of these other guys and probably solder something.

What would need to be done to create this scheme? Again, I don't have a lot of electrical experience, but would like to be able to provide one if possible.

If the button is held down when the speakers turn on nothing happens. The button only works once power is restored and you press down on it, at which point they immediately turn now, not when you let go of the button. So yea, likely will need to do some other sort of trickery to get it to stay on.

Sorry for the delay with this topic. Finally was able to test the Ohms for the 6 points NickG suggested.

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.
